Prodigy can't heal, no... BUT that's "not" Prodigy. It IS Prodigy, but from an alternate world. The young heroes across Marvel (including White Tiger and Power Man) are recruited to fight all invasion of all the dark dimension versions of the YA, while the YA takes the fight to Mother's home dimension (so as not to confuse anyone in battle). Anyone you see the young adult heroes fighting are NOT the true YAs. So the 'Prodigy' White Tiger is fighting is actually an alternate, villainous version (who might be able to heal, thinking about it; he is from an alternate world, after all, could have alternate powers).
