In 1999 he cut a big chunk of meat from a N.E.S.T.S soldier and he stopped the soldier right before the soldier pulled the trigger of his gun. And he also could kill a normal person with a mere aura (KOF 2001 story) and remain unscathed when a church falls on his body as seen in KOF AD.
can Wesker do this? how about neutralizing a god? how about shaking the ground with a mere powerup? how about being able to crush rocks in his hand? how about cutting through people with his bare hands? how about creating powerful flames capable of barbequing someone? how about being considered stronger than someone who can tear off an entire stadium with a glimpse of his power (goenitz)?
Iori's dealt with high speed and teleporters before. Iori's got enough speed of his own actually as KKF pointed out.
and i don't recall Wesker tanking an RPG or bullets.
