tocador you focus wayyyyy too much on weight class... the reason sumo's weigh so much is because they eat so much srsly I kid you not.
wario eats a lot, coupled with his human muscle build he has more flubber than muscle
while lucario on the other hand has animal muscle built like Adum said is many times stronger than a human, fat weighs more than muscle meaning lucario is very strong.
still don't see it?
EDIT: I can see everybody else understands, this is what happens when me and my alter ego team up... hell breaks loose
Im not saying that they are big because of muscles, i know its fat.
But do you really think that just because they are fat, they are weak?
I can guarantee you that a 1.8 meter normal guy, is way weaker than a 1.7 meter fat guy. I know fat isnt always muscle, but you do have more strenght and muscles, meaning you are stronger.
You are kinda wrong, muscles are heavier then fat, its just that people are usually fatter then stronger. And no, im not kidding.
And it isnt because "monkeys are proportionally stronger then mans" that any animal is stronger.
Lucario is kinda doggi'sh, not monkey'ish, and there is no proof he is stronger then wario. Adumb is making a assumption saying that "Sometimes animals are more well-build to have more physical strenght than human", but that isnt even true at all.
How can you explain a 70 kg mother lifting a 1ton car to save a baby, and a monkey, supossely 4-7 times stronger than her not being able to do so?
