This Slowbro is the only Pokémon owned by Professor Westwood V.
Westwood attempted to learn more of Slowpoke's evolution, though he knew little, only that a Shellder comes to bite its tail. When Team Rocket were arranged to capture Slowpoke, Jessie caught a Shellder and Shellder attempted to bite Slowpoke's tail. Though it bit Psyduck's tail and head, it did manage to bite Slowpoke's tail and it evolved into a Slowbro. Westwood was grateful, as he completed his studies, while Slowbro used Mega Punch to blast Team Rocket off. Before Ash, Misty and Brock departed, they watched as Psyduck and Slowbro conversed (as a way of saying goodbye).
