What is medicham weak against?

As an AI language model, I do not have personal opinions or beliefs, but I can provide factual information.

Medicham is a dual-type Fighting/Psychic Pokémon, which makes it vulnerable to several types of moves. Here are some examples of types that Medicham is weak against:

1. Flying: Medicham's Fighting-type weakness makes it highly susceptible to Flying-type moves. Attacks like Air Slash, Hurricane, and Aerial Ace can deal heavy damage to it.

2. Fairy: Medicham's dual Psychic-type makes it weak against Fairy-type moves, which include Dazzling Gleam, Moonblast, and Play Rough.

3. Ghost: Ghost-type moves are also super effective against Medicham due to its weakness to Psychic-type attacks. Examples include Shadow Ball, Shadow Claw, and Hex.

4. Bug: Bug-type moves can also deal massive damage to Medicham. Moves such as Bug Buzz, X-Scissor, and U-turn can be quite effective.

These are some examples of types that Medicham is weak against. However, it's worth noting that Medicham also has some resistances, such as Poison, Rock, and Dark, which makes it less vulnerable to these types of moves.
