What am I reading here. You are trying to tell me that one of the greatest speedsters of the OP verse, an marine admiral and highly experienced DF user, has problems with processing movements and reactions?
In every single of those situations he made a point of making fun of the situation or his enemies, it's his personality, not any kind of mental slowness on his part.
His kick of light "would" also obliterate himself too, can we stop arguing in this nonsensical way and disregard the whole notion of realism and real life logic already?
