Ever noticed that one of Eggman's robots are super savage? Yes, and that one savage bot is the one-and-only Orbot.

Don't believe me that Orbot is such a savage? Watch these, then.

Savage, Orbot. Just savage. Tell em, boi! XD

Fun fact: AU wise, Orbot was created and built by SpectraAlice during her work times with Eggman. So, one could possibly imagine that being the reason why the bot is uber savage.
