I don't and I never cared to be. I wanted Gren to be tough. I wanted his semblance to be useful but kinda weird. I wanted his weapon to be big, loud, and properly orky. At some point I'd like him to be able to fly around. I also wanted him to be a cyborg. Whether or not that makes him the strongest never mattered to me. I never go into a fight thinking that I can't lose. But I do try not to lose. At some point, Gren was given the label of "the strongest" even though I felt it was undeserved because I made no real efforts to gain that title, and because I knew he had problems that I wanted to resolve. Things like the fact he was slow, or his cybernetics makes aura and electricity interact with him weirdly, so on and so forth. Lugu calling Gren the strongest felt more like a curse because that meant to me, I couldn't give Gren anything else. He was already the "best" even though there was so much more I wanted to do with him.
