The Volcanoids live in the hidden lava underground. They have lava surging through their veins. They can blow lava out of their head, and mouth. They also work for Scorpion.
The first encounter is a boss fight in the Desert Sector. The Lyoko Warriors have never seen the creature before and Jeremie says that he will find his weakpoint. When the Lyoko Warriors start to fight against the Volcanoid, they can't damage it because of its lava head. Because of that, Jeremie says that he found the weakpoint. He says that Ulrich's Triplicate is the most effective against it and takes the lava from the head temporarily away and then, the Lyoko Warriors can damage it. However, they should do it fast or else the lava will return to its head and Ulrich needs to wait until he has enough power to use Triplicate again.
Later, it becomes a common hassle in the Volcano Sector.
- Volcanoids only appear in the Game: Code Lyoko: Quest for Infinity.
