aletraidi: Don’t know how big Jon is, but according to the height chart -thing (and snk wiki, but don’t go there if you don’t want spoilers, it’s full of them without warning) Reiner weights 95 kg and he can easily use the 3DGM. Maybe if you go well above 100 kg then it would be an issue?

Haha well if you wanna bring logic to it… he seems to have similar measurements with Reiner but he could weigh like 30kg more for all we know :-D different muscle density or something. Ghost anatomy, man

Not that a thing like 3DMG could work in the real world to begin with…
