the shape of the body changes (mega lop tapers into the pear shape a little differently)
the shape of the head changes, it's slightly slimmer and smaller. The eyes taper at the outer edges
every single limb completely changes shape, even the forearms go from a bell shape to a popeye-like bulbous shape. The legs get proper knees and the feet are no longer shapeness boot-like stubs
ears and eyebrows are completely remodeled, not just shit tacked onto the existing model
if you think Lopunny is on the same level of "garbage superglued onto the base form" as Mega Dragonite, you are beyond redemption and should be euthanized for the good of the species
