Diabla (Prime)

Diabla is a Decepticon who appears in Transformers: Universe.

Biography
When it comes to Decepticons, there's “vindictive”, and then there's Diabla. Small and unassuming at first glance, unsuspecting Autobots facing her will find that her deep-seeded hatred comes in many forms… Diabla's long-range ordnance can obliterate an opponent unawares, but for close encounters this hate filled fury can finish them off with her virus-infused armblades.

History
Diabla was part of the crew of the Leviathan when it shot down the Autobot ship Arclight over Central City. She and the other Decepticons on board went on to engage in a number of battles against the surviving Autobots in a number of places around the world.
