Vital statistics
Species Testudinian
Series Ben 10
Shellhead is Codon Stream's DNA sample of a Testudinian from Testudina.


Only heavy defense. But what Shellhead lacks in powers, he makes up for with hard-hitting melee attacks. He can charge into enemies with his shell and can tackle them as well. He can also retreat into his shell and spin fast in random directions like a wild top. The shell can fly if Shellhead is attacked.

First Appearance

It was only used by Ben 10,000 to defeat the enemy. Ben Tennyson later uses it to block all of Vilgax's attacks.
