I think with zac efron charismatic funny  charming  personality  he could be  perfect  as a superhero even with his darker stuff as in extremely wicked shockingly evil and vile " Ted bundy role, the paperboy Firestarter  he could  even be a good villan . His body type is amazing  fit and his acting go beyond  all the years  , also its been his dream to do spiderman  or xmen first class  . I believe  for a while now he is deserving for the part dc and marvel need to here me out they would make millions  just by his amazing  smile .
