Here's to hoping Gen 8 fixes this stuff with the power of the Switch's hardware. All the big mons got seriously fucked for some reason and seeing them during a battle just annihilates immersion. There's one trainer in USUM that uses Wailord and when it got sent out I had to double take, then laugh at how retarded it looked.

Strange though because I think Primal Groudon is actually pretty large, even if his normal form is another case of this shrinking phenomenon.
