OPINION ANNOUNCING THE JUDGMENT OF THE COURT
Justice EAKIN.Willie Clayton appeals from the order denying his petition for relief pursuant to the Post Conviction Relief Act (PCRA), 42 Pa.C.S. §§ 9541-9546. We affirm.
On March 30, 1982, following a jury trial, appellant was found guilty of first degree murder, robbery and possessing an instrument of crime (PIC) for fatally shooting Earl Grice in the head and taking money and drugs from his pockets. Appellant was sentenced to death for first degree murder, 10-20 years imprisonment for robbery, and 2%-h years imprison*398ment for PIC. On direct appeal, this Court vacated the judgment of sentence and remanded for a new trial because certain evidence had been improperly admitted. Commonwealth v. Clayton, 506 Pa. 24, 483 A.2d 1345 (1984).
Upon retrial, appellant’s case was consolidated with other charges against him for an unrelated murder and robbery, and the jury found him guilty of first degree murder in both cases, as well as two counts each of robbery and PIC. He was sentenced to death for each murder conviction, and to 10-20 years imprisonment for each robbery. The sentence for PIC was suspended. On direct appeal, this Court affirmed the judgment of sentence. Commonwealth v. Clayton, 516 Pa. 263, 532 A.2d 385 (1987), cert. denied, 485 U.S. 929, 108 S.Ct. 1098, 99 L.Ed.2d 261 (1988). Appellant was represented by the same attorney in both trials and direct appeals.
Appellant filed two identical pro se PCRA petitions on May 13, 1988, and June 7, 1988. Counsel was appointed and filed an amended petition raising 19 issues. PCRA counsel was subsequently permitted to withdraw, and new PCRA counsel was appointed and filed a supplement to the amended petition. This supplement withdrew nine issues as meritless, retained ten issues and raised four additional issues. After an evidentiary hearing at which one issue was argued, the PCRA court dismissed appellant’s petition. PCRA counsel filed a notice of appeal along with a motion to withdraw as counsel because of the issue of his ineffectiveness as PCRA counsel. This motion was granted and present counsel was appointed. See Commonwealth v. Green, 551 Pa. 88, 709 A.2d 382, 384 (1998) (explaining general rule that counsel cannot raise own ineffectiveness, but where it is clear from record that counsel was ineffective or issue is meritless, appellate court can address it without appointing new counsel).
The basis of appellant’s entire appeal is grounded in the assertion PCRA counsel was ineffective. Appellant contends his second PCRA counsel was ineffective for filing “a scant supplement to an initial amended PCRA petition that raised very few issues, and none of them non-record based claims.... ” Appellant’s Brief, at 7. He further claims both *399prior PCRA counsel “were ineffective for failing to discover, investigate, and litigate both non-record mental health and record based claims for relief ... of arguable merit.” Id., at 10. Specifically, appellant asserts PCRA counsel was ineffective for failing to investigate and present the following issues:1
(1) Whether trial counsel was laboring under an impermissible conflict of interest during his representation of appellant.
(2) Whether the Commonwealth used peremptory challenges to exclude jurors on the basis of race.
(3) Whether appellant’s death sentence was the impermissible product of racial discrimination.
(4) Whether the jury instructions by the trial court during the penalty phase were unconstitutional because a) the jury was told to count rather than weigh aggravating and mitigating circumstances; b) “preponderance” was erroneously defined in the context of assessing the presence of mitigating factors; and c) the jury was not instructed that aggravating factors must be unanimously found by each and every juror.
(5) Whether trial counsel failed to investigate and present readily available mitigating evidence of appellant’s history of organic impairment, child abuse, domestic violence, dysfunctional family history and emotional trauma during the penalty phase of appellant’s trial.
(6) Whether newly discovered evidence demonstrates the trial court materially misled the jury by failing to instruct that appellant would be statutorily ineligible for parole if sentenced to life.
(7) Whether the trial court improperly allowed the Commonwealth to exclude jurors for cause who voiced concern about the death penalty but also unequivocally indicated they would follow the law.
*400(8) Whether the “proportionality review” by this Court provided meaningful appellate review.
(9) Whether the jury instructions improperly shifted the burden onto appellant and relieved the Commonwealth of proving every element of the offense beyond a reasonable doubt.
(10) Whether trial counsel was ineffective for failing to object to the trial court’s guilt-phase jury instruction, which informed the jury of the maximum sentence appellant could receive for each degree of criminal homicide.
(11) Whether trial counsel was ineffective for failing to investigate and argue that another person was responsible for the murder.
All of the above issues, except issues 6 and 8, pertain to alleged errors at trial; however, because they were not preserved by objection at that stage, in post sentence motions, or on direct appeal, they are waived. 42 Pa.C.S. §§ 9543(a)(3), 9544(b). Issue 6 attempts to avoid the PCRA’s time-bar. Issue 8, which pertains to alleged error on direct appeal, was not preserved by being pled in appellant’s PCRA petition. Therefore, these claims themselves are lost as grounds for relief; to obtain relief, appellant must “layer” them beneath claims of all prior counsel’s ineffectiveness since neither trial, appellate, nor PCRA counsel raised them. See Commonwealth v. Wallace, 555 Pa. 397, 724 A.2d 916, 921 (1999); Commonwealth v. Christy, 540 Pa. 192, 656 A.2d 877, 888 (1995), cert. denied, 516 U.S. 872, 116 S.Ct. 194, 133 L.Ed.2d 130 (1995); Commonwealth v. Chmiel, 536 Pa. 244, 639 A.2d 9, 12 (1994) (ineffectiveness of prior counsel must be raised at earliest stage in proceedings at which counsel whose stewardship is being challenged no longer represents defendant), cert. denied, 528 U.S. 1131, 120 S.Ct. 970, 145 L.Ed.2d 841 (2000).
It is the ineffectiveness claim, not the underlying error at trial, which is reviewed as a potential basis for relief. See Commonwealth v. Williams, 566 Pa. 553, 782 A.2d 517, 535 (2001) (Castille, J., concurring) (underlying claim is relevant only as it bears upon Sixth Amendment ineffectiveness *401analysis). Thus, appellant’s claims of PCRA counsel’s ineffectiveness are distinct, substantive claims, separate from the underlying claims of trial court error and trial counsel’s ineffectiveness. See Commonwealth v. Lambert, 787 A.2d 327, 336 (Pa.2001) (Opinion Announcing the Judgment of the Court) (“claims of counsel ineffectiveness are ... analytically and constitutionally distinct from the underlying claims to which they relate.”); Commonwealth v. Bracey, 787 A.2d 344, 360 (Pa.2001) (Castille, J., concurring) (same).
Appellant must satisfy all three prongs2 of the ineffectiveness test with respect to PCRA counsel. Appellant must demonstrate: (1) the underlying claim is of arguable merit; (2) the particular course of conduct pursued by PCRA counsel did not have some reasonable basis designed to effectuate appellant’s interests; and (3) but for PCRA counsel’s ineffectiveness, there is a reasonable probability that the outcome of the proceedings would have been different. See Commonwealth v. Kimball, 555 Pa. 299, 724 A.2d 326, 333 (1999). Failure to address any prong will defeat an ineffectiveness claim. Lambert, at 337 (“appellant’s failure to forward relevant argumentation as to each necessary ‘individual facet’ of the Strickland standard dooms his boilerplate claims to failure.”); see also Williams, at 525 (cautioning that “PCRA counsel generally must, in pleadings and briefs, undertake to develop, to the extent possible, the nature of the claim asserted with respect to each individual facet of a layered ineffectiveness claim ....”) (emphasis supplied).3
*402Although appellant argues the merits of the underlying claims in great detail, he has failed to develop the remaining two prongs concerning ineffectiveness. At the beginning of the argument section of his brief, appellant states in general terms that his claims of all prior counsel’s ineffectiveness have arguable merit, that PCRA counsel’s failure to investigate these issues ■ constituted deficient performance, and the dismissal of his PCRA petition, resulting in an invalid conviction and death sentence, prejudiced him. However, appellant never develops his argument concerning PCRA counsel’s performance; he focuses only on the alleged trial errors and trial counsel’s stewardship, and at the end of his discussion of each issue, he “layers” it by tacking on the statement, “[a]ll prior counsel were ineffective for failing to litigate this claim.” Appellant does not address how PCRA counsel’s failure to raise these claims lacked a reasonable basis designed to effectuate appellant’s interests, or how the outcome of his PCRA proceeding would have differed had these claims been advanced; indeed, he offers no argument at all concerning PCRA counsel’s actions. See Lambert, at 337 n. 9, 339 (counsel cannot be deemed ineffective per se for failing to pursue claim of arguable merit; “reasonable basis” and prejudice prongs must also be established).
Furthermore, it is a well settled principle of appellate jurisprudence that undeveloped claims are waived and unreviewable on appeal. Williams, at 532 (citing Commonwealth v. Williams, 557 Pa. 207, 732 A.2d 1167, 1175 (1999) (recognizing “unavailability of relief based upon undeveloped claims for *403which insufficient arguments are presented on appeal”)); Pa. R.A.P. 2119(a). In Commonwealth v. Albrecht, 554 Pa. 31, 720 A.2d 693 (1998), this Court held the relaxed waiver rule, applicable in capital appeals, is no longer applicable in PCRA appeals. See also Lambert, at 336 (question of waiver under § 9543 is distinct from question of whether appellant has sufficiently developed ineffectiveness claims in appellate brief so as to enable this Court to conduct effective appellate review); Williams, at 528-29 (Zappala, J., concurring) (§ 9543’s requisites pertain solely to eligibility for relief, and not to any prerequisites petitioner must satisfy to have court consider claim; “[tjhis is not to say that our Court is precluded from dismissing a claim on appeal from denial of PCRA relief on the grounds that the petitioner failed to adequately develop an argument in support thereof....”). Therefore, appellant’s failure to develop any argument at all concerning the second and third prongs of the ineffectiveness test with respect to PCRA counsel results in waiver of these claims.4
Finally, we turn to appellant’s sixth issue, in which appellant claims the trial court erred in failing to instruct the jury that a life sentence means “life without parole,” and that all prior counsel were ineffective for failing to raise this claim. Appellant’s ineffectiveness claim fails for the same reasons all his other issues do; however, he also argues he is entitled to relief pursuant to 42 Pa.C.S. § 9543(a)(2)(vi), based on after-discovered evidence in the form of statistics demonstrating the infrequency with which clemency is granted, and surveys demonstrating the public’s mistaken belief that individuals sentenced to life imprisonment are usually released. Contrary to appellant’s contention, this “new evidence” is not exculpatory, as required by § 9543(a)(2)(vi). This issue is meritless.
*404The PCRA court’s order denying appellant’s petition is affirmed.5
Justice NIGRO files a concurring opinion. Justice NEWMAN files a concurring opinion. Justice SAYLOR files a concurring opinion. Chief Justice ZAPPALA and Justice CAPPY concur in the result.. Contrary to appellant's assertion, the first issue was raised in both the amended and supplemental PCRA petitions; the second issue was raised in the amended petition, but was withdrawn from the supplemental one.
. In Commonwealth v. Pierce, 515 Pa. 153, 527 A.2d 973 (1987), we recognized the "performance and prejudice” ineffectiveness test in Strickland v. Washington, 466 U.S. 668, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984) was the proper test under the Pennsylvania Constitution. "This Court has come to characterize the test as a tripartite one, by dividing the performance element into two distinct parts, i.e., arguable merit and lack of reasonable basis.” Lambert, at 337 n. 8. Although the ineffectiveness standard is the same under the PCRA as it is on direct appeal, Kimball, at 331-32, the right to elfeclive counsel in an initial PCRA proceeding arises from the Pennsylvania Rules of Criminal Procedure. See Pa.R.Crim.P. 904 (formerly Rule 1504); Lambert, at 338.
. In Williams, the majority concluded a remand was necessary because the PCRA court had failed to provide sufficiently specific reasons for summary dismissal in its notice pursuant to Pa.R.Crim.P. 1507 (now *402Rule 907), as well as failed to provide its own reasons for dismissal in its Rule 1925(a) opinion; it adopted the Commonwealth's motion to dismiss. Williams, at 527. Since amendment of PCRA petitions is to be “freely allowed to achieve substantial justice,” Pa.R.Crim.P. 905(A), the notice of summary dismissal must alert counsel to deficiencies in pleading so that the potential for amendment may be reasonably evaluated. Williams, at 526. Here, unlike Williams, we are not concerned with "gaps” in issues already pled in a petition which was dismissed without a hearing; we are dealing with issues never raised in the petition, on which there was a hearing. Accordingly, remand would be inappropriate. We will not revisit the issues appellant wants raised in hindsight, having already had one unsuccessful bite at the post conviction apple.
. Wc are aware this decision raises tlie issue oí appellate PCRA counsel’s ineffectiveness for failing to properly develop the issue of all prior counsel's ineffectiveness in his appellate brief; however, appellant would appear to be time-barred from filing a second PCRA petition raising appellate PCRA counsel’s ineffectiveness, since his judgment of sentence was final nearly ten years ago. 42 Pa.C.S. § 9545(b)(1). At some point, even capital cases must become final.
. The Prothonotary of the Supreme Court is directed to transmit the complete record in this case to the Governor in accordance with 42 Pa.C.S. § 9711(i).
