TMNT/ Tarzan: I would probably only have one turtle for this story. Either Don or Leo would make an interesting matchup with Tarzan. Maybe it could dabbled into a contrast between the existence of an animal integrated into human society and a man who's integrated into animal society.
The original Tarzan book series hit public domain this year.
Only a matter of time before a small indie comic book company runs with it. Of course, there have been numerous Tarzan comics through the years, but none of them really stood out.

TMNT X Sonic crossover would be dope as hell
That would make complete sense and it would be an easy way for IDW to print money.

John Wick. Let’s see him stab Shredder to death with a pencil. A f-cking pencil.
Damn, we're about four years too late for that to happen. This definitely would have been possible.

Out of all potential crossovers, this might be the most obvious one.
Sadly, the last time Marvel had a real bonafide crossover with another company was in 2004 with JLA/Avengers.
