Shellhead is the Omnitrix’s DNA sample of a Relounian from the planet Perska.

Height - 9 Ft

Body - Tortoise

Durable Shell - Shellhead is covered in a highly durable amour-like shell, he is able to retract his head and arms within his shell for extra protection. His shell grows over his head and under body as well as extra bumps.

Enhanced Digging - Shellhead can burrow into the ground at high speeds.

Spinning Force - Whilst he is encased in his shell, he can spin himself around on any surface and zoom through on his bottom-side (his tail).

Slow Mobility - Shellhead’s body shape (along with his heavy shell) makes him very slow on foot. He needs to spin in his tail for quick mobility.

Balance Issues - His body shape can be difficult to balance as his legs are very stumpy, which can cause him to trip over when caught off guard.
