__NOEDITSECTION__ Magma Ruins (called Magma Catastrophe in the N64 titles) is a that appears in Custom Robo (Nintendo 64), Custom Robo V2, Custom Robo (GameCube), and Custom Robo Arena. It is surrounded by Magma that rises as the battle progresses. As the Magma rises, there will be less room for players to maneuver around, resulting in heated (no pun intended) and intense battles. One tactic is to Charge into the opponent while their back is towards the magma, thus pushing them into the magma.
