Offspring name: Glapu Glulu-Mega @ Glalitite
New type: Ice / Grass
New base stats: 75 / 165 / 97 / 122 / 87 / 117 | BST: 623
New ability and desc: Refrigerate
Notable moves: Same as above, plus Return/Frustration, Double-Edge, Explosion, Façade (technically has a usable SpA stat too but its physical movepool is plenty)

It also has a good speed tier but still has that horrible defensive typing.
