Piranacon

Piranacons are a race of piranha fish-like mechanoids occasionally descended from Cybertronians who are often affiliated with the Quintessons.

Anatomy
Piranacons share a similar biology to other Cybertronians, except they transform into robotic piranha fish. They are functionally Micromaster versions of Sharkticons.

Powers and abilities
Piranacons share many of the same abilities as Cybertronians.

Much like Earth piranha, Piranacons swarm in en masse, making them capable of breathing underwater.

Piranacons can devour a full-sized robot in a few seconds with their razor-sharp teeth and claws.

Weaknesses
Individual Piranacons are not especially durable, as they can be easily defeated by well-trained Cybertronians.

Piranacons can be easily persuaded to switch sides, meaning they are sometimes not very intelligent.

Culture and society
Piranacons are creations of the Quintessons, who may give a bunch of them to allies as a goodwill gift if they happen to feel like it.
