I think the MC would've Won the Evander Devana Fight no sweat. The only reason he didn't is because of Shen, who's Level 4. The way the MC is portrayed in a Fight, and the Body Trait itself, at least, in his hands, is very Spongy. Sure, it may seem like he took a big hit or that he's basically a punching bag, and in some sense, he is. But that's just it, Valravn describes it best; it's disheartening to see your foe suffer a blow the same as you in a Fight, but then get right back up, completely renewed. Body is a Power I EXPECT to get tossed around with the way it's portrayed, but I also know it's gonna either Outlast the entirety of a Fight even if it's slightly outclassed, or it's gonna fall without contest to a clearly overly stronger opponent.
Devana didn't even stand a chance. She created Monsters and shit, big deal, she was practically MIA half the Fight because her Durability couldn't keep up with our Pounding. Evander on the other hand, well, he was putting up a good fight. I don't think it would've been enough to actually win, but his Power being Destruction, is literally a direct counter to the Body Trait.
Anyways, I remember a lot of people whining about that Fight when it came out. I don't really understand why though, if the MC Fighting TWO Level 3s wasn't enough, Shen was also there. He wasn't even really struggling, just trying to figure out the best way to win whilst protecting the Twins before Shen surprised him. If it was two Level 2s, THEN I would've been mad at the struggle, but it wasn't, so I think the Fight was fine. Disheartening that we had to lose mind you, but fine from a Narrative/Power Scaling Standpoint I guess.
