Seebik is a minor antagonist from the Ben 10 series.
Seebik has red skin with black markings on it, yellow eyes, large eyebrows, and almost puma like nose and mouth. For his normal clothes, he wears a blue shirt with spikes and a furred hood, blue pants, and boots. Under this clothing, he wears a standard Kraaho outfit, being a red strip of cloth.
When Ester's father died, Seebik took control of his Kraaho tribe, turning them into a band of bandits.
He first appears in the episode "Hot Stretch", planning to bring magma out of the Earth and make a new colony for his tribe. However, he was defeated by Ben and without his knowledge, he passed his leadership to Ester.
He later appeared in "Special Delivery", where he among several of his men planned to take the Dwarf Star. Judging by his hope to not be found out, it's possible he was planning to commit mutiny.
