Indeed he was. He even had his own personal mecha. God that was awesome.
Charlie Huntress cracked me up, especially hen thy referenced it near the end of the BoP with Charlie going "I totally want to be like you Huntress, but maybe with fishnets too and I'll do something with my hair"
Or Beetle mentioning her when Misfit came into the Tower Beetle: "Didn't I fight a blond you?" Misfit: "Was I awesome?"
But yes I now want Hiro to show up in the Powergirl title. It'd be glorious.
