The Ring of Fire Part 3

Also known as Suicide B.A.T.s, they have replaced the depleted numbers of Cobra Suicide Vipers*. These new breed of B.A.T.s have advanced intelligence. Their thinking capability is almost human. They carry less firepower than regular B.A.T.s not only to give them more aerial maneuverability while using their flight gear but also because they almost need no weapon for they are already walking / flying time bombs. Within their armored bodies rests a bomb.

They can self detonate anytime to destroy the enemy.
Cobra Commander needed to offer 6 innocent human sacrifices to be offered to the mouth of each volcano located in the 6 corners of the Ring of Fire to unleash the Snake Demon, and he sent Vampire B.A.T.s to search and kidnap 6 poor souls.
