what tbe fuck

i think it means his defense didnt work against the orange haired dude

Well, in certain video games, when you have to fight, you can unlock special attacks or skills that do not care of the defense points of the opponent (like, even if he had some defensive points, those won't be active, although there use is to reduce the impact and damage of the opponent 's attack)... i think its something like that since the comics is based on a video game world (=・ω・=)
