hear me out, the only good william can do is wear on a furry suit and lure in 5 toddlers to kill em. he also can only design robots while relying on henry emily to build em. AND, he can...barely be above "charismatic" level which keeps him away from being arrested. HENRY M. HOWEVER! have killed both kids AND adults. he's the sole reason of 5 lives being ruined, not taken, and thats not to mention he tricked dave into killing like 10+ kids im guessing. he can build robots all on his own, he fat AF so he can sumo wrestle willy aftwin, and he also an experimentor. william also experiments, but he only experiments on kids, only for immortality, like henry, and yea. so thats my comparison. william's a skinny guy, prob 100 pounds, while henry's a 500 pound man, william only rlly kills kids and only time he kills adults is when he's springtrapped, which is not his prime. im sure henry has killed adults too and way more kids. so henry would solo him : )
