Is Rhydon Good in Yellow Playthrough?

Devastating in the matchups it wins. Rhydon hits harder physically than almost anything in Gen 1 and handles Blaine and most of Agatha's team. The massive Water and Grass weaknesses are the trade-off, and both show up constantly at the E4.

Rhydon Weakness

Rhydon is weak to Water, Grass, Ice, Fighting, and Ground. Watch out for Water and Grass attacks, those deal 4x damage. On the flip side, it's immune to Electric-type moves entirely. 5 resistances help offset the weaknesses. Rhydon's physical bulk (base 120 Def) helps cushion physical weakness hits, but special attackers are the bigger threat.

Y Rhydon Best Moveset

One of the most physically threatening Pokemon in the format with 130 Attack powering MoveEarthquake for devastating Ground TermStab. Rock coverage adds a second angle, and MoveBody Slam layers paralysis pressure on top. The 4x Water weakness is the one vulnerability that matters, and Water-types exploit it mercilessly.

TMs carry this one. Rhydon learns Earthquake and Dig naturally for STAB, but the offensive range comes almost entirely from technical machines. Normal and Ice and beyond give it real matchup play.

Pokemon Yellow

Rhydon Yellow Guide

  • Trade a Golduck to the old man in the trade room of the Pokemon Lab on Cinnabar Island to get a Rhydon nicknamed BUFFY. This is an NPC trade, so the Rhydon you receive is yours immediately, no transfer cable needed.

  • In Yellow, Rhydon has 485 BST, so weigh it against what your team already covers.

  • In Yellow, Rhydon plays as a wall. It's slow, so Trick Room or priority moves are key. so pick your spots carefully. Earthquake is the primary attack.

Game Availability

One of the original 151, Rhydon has appeared in 21 games: nearly every mainline game. From Red & Blue through the latest titles, it's rarely been left out of a regional Pokedex.
