I'm not sure about it, but i don't know.

but the slasher characters are more likely to appear.

Now, Lester 'Beetlejuice' Green fights for real (actor/pugilist).

@DAHK9 no i meant the ghost with the most

Notice how as a minor in a kid's animation of 'Teen Titans Go' with Betel Geuse Jr there's a reference to different Titans (in the title obviously), what a coincidence . Not that I take it seriously but it makes me contemplate Kronika, but this is undeniably different. So using this, and making something out of more or less nothing, I see him as a pawn of the Titaness if he was DLC. This is the only way I could see links with Betelgeuse being a fighter in MK, not that it's meaningful.
