As far as I remember, Mister Sinister has had a Red Diamond on his forehead, such as this image from 1989.

Mister Sinister from 1989

I can't find anything online to explain this gem. Is it just aesthetics, or does it serve a purpose?

  • @Valorum I saw that before posting, but I don't have access to that to know it's the reason. Also, who's to say I don't have my own fashionable head diamond 🤷‍♂️
