Is Slowbro Good in Yellow Playthrough?

Water/Psychic with almost no bad matchups in Gen 1. Slowbro handles Giovanni, Bruno, and most of the E4 through sheer bulk and special firepower. Dead last in speed but almost impossible to take down once it gets going.

Slowbro Weakness

Slowbro is weak to Electric, Grass, and Bug. On the flip side, it's immune to Ghost-type moves entirely. The Water/Psychic typing picks up 5 resistances to work with. Slowbro's physical bulk (base 110 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.

Y Slowbro Best Moveset

MoveAmnesia doubles the already-solid 100 Special, and 110 Defense absorbs physical hits while the stat climbs. MovePsychic hits from a type nothing resists, MoveSurf adds Water coverage, and MoveThunder Wave paralyzes what threatens the setup. Blocks both sides of the offensive spectrum after one boost.

Moves List

Most of Slowbro's flexibility comes from TMs. Same-type output runs through Psychic and Surf, but Normal and Ice and the rest of the TM pool push it from predictable to genuinely threatening.
