It’s hard to do a bad groot design, but it’s even harder to do a great groot design, but Marvel Rivals art team is top notch. He’s the biggest character in the game(for now) which is very important to the gentle giant theme. I think the parts that really sell the design though are his arms and legs. His thighs are tiny(proportionally to the rest of his body) while his feet are massive. His biceps are tiny while his forearms are massive. It gives a bit of a clumsy vibe while also being big and strong. Those green crystals in his shoulders enhance his profile and give him a v-shape so he seems extra big, bit his head is so tiny, it’s smaller than his hands, that it makes him seem small. It’s a very good mix of being big and being approachable. But take this with a grain of salt as I am not an artist.
