Cyclop's optic blasts vs Havok's hand blasts vs Iron Man's proton beam
Imagine these heroes getting really pissed and just letting loose their respective energy blasts, holding nothing back. Which would be the most destructive?
I pick Cyclop's optic blasts because they're incredibly stronger when his visor is off. Iron man is a close 2nd cuz his proton beam gun from the video games is just HUGE.
