What is rhyperior weak against?

Rhyperior is weak against water, grass, ground, fighting, and steel-type moves. It takes double damage from water-type moves and four times the damage from grass-type moves due to its rock and ground typing. It is also vulnerable to fighting-type moves that can deal heavy damage to its rock and ground-based defenses. Additionally, steel-type attacks can also be effective against Rhyperior, as they can exploit its weakness to these types of moves.
