Hah, I can just see Onomatopoeia actually being all stalkery with Thomas Wayne, Jr....

Which reminds me, did your CS explain why he takes their masks? Or why he has an accelerated healing factor?

I believe the bio explains the masks. The healing factor is noted to be part of his metahuman gene.

Edit: The bio notes that the masks are trophies. My first IC post I obviously expanded upon the motive. I can edit the sheet if you wish.
