well, maybe try this guy,

I made a feeble attempt to put you together in a photo to see if he would be a suitable lackey. He has served in a similar position before but never for someone as asteemed and worthy as yourself...

he even has his own cape (not as long as yours of course) and a small mask, *(not as magnificent as yours either) *and even some kind of home made uniform
he also had a very simple human name: Robin (but you can of course feel free to call him whatever you want)
