2. Cloning? Didn't happen. It was a mirror-move. There was no clone, it vanished. Goku effectively blasted himself.
3. Matter manipulation. Janemba's is faulty. He can't maintain it. Meanwhile, 90% of the Annihilators team has the same power, only better, more controlled, and can actually do things with it that Janemba could never fathom. IE: Surfer scattering his individual atoms across lightyears and phasing him out of existence.
4. Regeneration is pointless since it was easily defeated and his regen is halted by Harsh Language. Giant weakness there. Something the Marvel team doesn't have to worry about.
