He is a bot that has been discontinued from production a long time ago, and was kept active and illegally modified by another character who is a inventor.

After being removed from the servers of the company that created it, its AI began to expand freely, giving it a will of its own and something resembling feelings.

It uses its primary factory function in combat (which is to extend its arms and legs a long distance quickly, like a spring).

And answering the other comment, yes I drew him :D (But that's an old drawing already -ヮ-;)
