I don't tend to make guarantees on characters coming to fighting games but I can guarantee you the only way Death will be playable is when someone on PC model swaps her for the lulz
The character since inception is meant as an abstract, not as a boss to overcome
Now listen all you boys and girls,
All around the world,
Don't be afraid to get up and move!
You know that we're all Super Stars,
We're the ones that made it this far!
Put a smile on that face,
There's no time to waste,
Oh, let's do The Odyssey!
