Pure Poison typing offers almost no offensive value in Red & Blue, and Arbok's middling stats keep it stuck at F-Tier.

Is Arbok Good in Red & Blue Playthrough?

Arbok hits decent for the mid-game but struggles to find targets that actually take big damage from Poison. Most of the important fights are against Rock, Ground, Psychic, or Water teams, and Arbok can't threaten any of them. Fills a slot if you need a body, but there are better options by the time it evolves.

RB Arbok Best Moveset

Poison typing has no offensive value and the stats can't support a defensive role. Physical moves like MoveEarthquake do most of the work since Poison attacks don't threaten anything at the top. A filler pick with nothing unique.

Arbok Red & Blue Guide
