Cap.
If u need to break it down, u can say Cap has all those impressive "Capwins", due to experience, training, will, intelligence, intuition, etc, etc, honed over many years of constant combat with the most dangerous beings in multiple universes.
Triath does not have anything like that.
If u want to chuck that out the window, that's cool. But somebody is going to have to open a thread where we can track, retcon results and dethrone a whole big bunch of favorite characters who use the same kind of details for victories.
I sh*t on your shiny, new Triathlon.
He can come try again when he has some hair on his balsawood airplane.
