Niggas, there's easy proof that Gohan>Gotenks>Goku, and that Goku=>Kid Buu, and thus Gohan = strongest UNFUSED character. First, easiest thing to point out, is that Goku was scared shitless of Super Buu. and said no matter what he and Vegeta did they were done for and dead. Super Buu actually had Goku shook. Gohan came and beat the everloving shit out of Super Buu, and Goenks(SSJ3) was around even with that nigga if not slightly stronger. That alone Gohan>Gotenks>Goku.
When fighting kid buu, Goku states that he can kill him if he charges a blast at full power, but can't because he's fighting Kid Buu and he won't get the chance, and SSJ3 drains energy like a mofo. Then Vegeta suggests a plan And Goku thinks Vegeta wants to bring Gohan And/or Gotenks back to life to kill Buu easily. But instead he does that weak spirit bomb shit " make the earth protect itself for once" and all that. And Dende was the guardian, but it didn't matter since Earth was destroyed. The dragonballs they used were Namek's so Dende was unneeded. Gohan, Goten, and Trunks, on the other hand would have won instantaneously.
And besides that I can't find the interview stating Gohan>GOku, but facts suffice.
