Jumbolias

Jumbolias is Nova's pet manta ray in Asgard.

History
Nova found him when Kootra punched him off the Rainbow Bridge. He wanted to get back home fast so he rode the nearest manta-ray and tamed him. As soon as he finished naming it he started taking damage, which killed him. When he gathered his stuff, he had lost Jumbolias. He either ran away or was killed with Nova. Jumbolias' true fate is still unknown.
