Astro (Astro Boy 2009)/Bio & Battles

"You know, I tried to find my place in the world. I - I thought I found it, but I guess fitting in can be a lot more complicated than it seems, huh?"

- Astro

Astro is a robot replica of the late Tobio "Tobi" Tenma, the son of robotics expert Dr. Tenma in order to bring his son back to life. This backfired, however, as the replica only served as a painful reminder of his son's death. Upon discovering his newfound robotic capabilities the replica confronted Tenma who explained his true nature and rejected him as his son. Distraught, the replica flies away only to be pursued by Metro City's law enforcement lead by President Stone who wishes to obtain the blue core the replica was powered by, leading to him falling to the polluted surface.

After waken up, the replica found himself met a group of children who were looking for old robots to be used in their surrogate father Hamegg's robot fighting ring, who also happens to be a robot repairman. He also meets a trio of inept revolutionary robots called the Robot Revolutionary Front (RRF), who dubbed him 'Astro'. Astro lives with the children and Hamegg for a while, even repairing a giant old robot who they name Zog who they plan to use for the fighting ring. When Hamegg discovered Astro's robotic nature, he incapacitated him and forced him to fight as well. Just as Astro and Zog began to rebel, Stone's forces arrive and take Astro back to Metro City.

He was taken to Dr. Tenma and apologized for not being a good enough substitute for Tobi and agreed to be deactivated so that the Blue Core could be extracted. Having a change of heart and realizing that even though Astro isn't Tobi, he's still his son, Dr. Tenma reactivates him and lets him escape. Furious, Stone sent the red core powered Peacekeeper to get him back, resulting in a fight that destroyed Metro City's power core, causing the city to crash to the surface. Realizing that the Peacekeeper is too unstable, Astro sacrificed himself to destroy it, but was revived by Zorg just in time to defend Metro City from invading aliens.
