Robots assemble

One one side you have the famous (okay maybe not) team of Big Guy and Rusty.

On the other side Iron Giant and Astro Boy

Which giant robot and his boy robot partner wins? Fight takes place in London, but no living thing is in the city.

Dont know anything about the first team, cept Rusty always seems to bug me >.>, Astro kills Rusty and Iron giant goes into his battle mode.

Astro teaches them all how to be friends, whether they like it or not.
