No, I'm not saying he's impervious but he is supposed to be "the fastest man alive" I mean any projectile at him should be like a 2 year old toddler girl trynna throw a baseball at you.
And its not like its some heavy duty amor... the shyt that Batman or Cyborg has on them.... its reasonably has to be lightweight (so it dont slow him down as much right?). So again, what is the purpose of metal suit when you're a fast, quick, and nimble fighter with the highest level of agility? That shyt will really does do much to enhance him in ways thats he has a weakness.
Aesthetically.... just seems weird to me but I dont despise it like some of the DC Stans in here who are now getting shamed and called out to be Marvel stans when they aint even reppin Marvel, yet alone mention them
