>>40085712LGPE does not have scaled Pokemon though.They did Onyx and Gyarados size adjustments, but 99% of the big Pokemon other than them are significantly smaller in battle. MELMETAL in particular is weird as hell since in overworld hes bigger than Snorlax but a huge manlet in battle.
It's clear they only bothered to do it for Onyx and Gyarados but in general prefer to keep them small.
