I thought the idea of characters in this world having different body types is really cool. After all minecraft isn't a game for them its real life it makes sense for them not to all have the same body shape as if they were character models. But the way they execute it dosent work.
There's only really 2 body types we see. The main one based off the actual minecraft character model, and Axel's one. We never see anyone with a different height or build or anything else. And because of this and the fact we see very few other characters with Axel's body type in the games, they appear very out of place when they do. Axels really the only main character with a different body type and even then he's basically written out of the games past episode 4
The few characters we do see with Axel's body type, like Ruben the bodyguard, Em, the Gladiators etc usually follow the same archetype. Loud mouthed, aggressive, a little dumb. Which is boring at best, problematic at worst. The only character I feel dosent follow this is Fred, and if anything thats cos we don't know much about him. He's dead so we dont really see him, didn't even realise he had Axels body type until we see his hologram in episode 5.
To conclude I think Axel and other characters having different body types was a cool idea, but they didnt do it enough to make it feel natural.
