So for a while I've had this headcanon that XLR8's clothes are made of ferrofluid. Ferrofluid is attracted to magnets, and according to the show's lore, XLR8's immune system is electromagneticly charged, so I thought him wearing ferrofluid would have been cool.

I decided to develop this idea further by having him use the same ferrofluid he wears to make his own weapons, kind of like how Bayonetta wears and fights with her hair.

And, like Bayonetta, he's completely naked without the substance covering him.
