Cragsters

The industrious miners known as the Cragsters live in a vast network of tunnels and caverns dug deep underground.

Members
Krader - The tough, serious, no-nonsense leader with a huge drill hand. Seismo - The shy and quiet one with earthquake-causing feet.

Shuff - The cute, clumsy, and helpful one who breaks everything with his wrecking-ball-like body.

Infernites
The Cragsters (especially Seismo) are best friends with Flain, and they often play Rockball or ride on Lava Slides together. However, they dislike Zorch (Seismo dislikes him the most), to the point where some of them are scared to Mix with him at times. However Krader is neutral towards him.

Electroids
Shuff and Volectro seem to have a good relationship, along with Krader and Volectro. The rest is neutral.

Frosticons
Everything is neutral so far.

Fang Gang
Everything is neutral so far.

Flexers
There have been rumors that the Flexers don't like Krader, but this is proven to be provided untrue, therefore they are neutral with him and the other Cragsters.
