Cerberus

Overview
A large, multi-headed dog with wings, this summon had a number of body piercings and the Seikatsugan, implying it was being controlled by Stan Uzumaki. Its fur was all brown-colored and it had a giant black receiver stuck through its head. It also had black coloring around its mouth along with razor sharp teeth and fangs.

Abilities
It was modified by Stan using the Amplification Summoning Technique, so that it can split apart, when struck, into individual dogs that can then merge back together. It gained additional heads every time it splits in this way, and each duplicated head carries the black receiver and the Seikatsugan like the original. According to Stan, the only way it can be defeated is by defeating its original summoner. This summon has been seen at different sizes, ranging from several stories tall to just tall enough to fit underneath trees. Cerberus has been seen to be extremely resistant being able to withstand devastating attacks with minimal damage.
