Fiction

Keroro Gunsō × Transformers

When negotiations with Starscream failed, the Keron Army pulled out the Oozon to steal Starscream's energy and data so they could produce copies of the Decepticon for themselves. Angered at the idea of Starscream being subservient to the alien frogs, Starscream took a swipe at the machine and broke it. The sucked energy, with nothing to contain it, jumped to Keroro, granting him the power of transformation. Keroro Gunsō × Transformers
