Power Ranges Death Game

[MakBow]

Not going to lie, I've seen regular power rangers, I've seen isekai power rangers, where's my death game power rangers?

That would lowkey be tuff when you really think about it unless it already exists.

Kamen Rider Ryuki might satisfy you.

Since the Power Rangers have crossed over into all sorts of other media (I was trying to track down the Power Rangers vs. Godzilla series when I lost my job and couldn't afford comic books for a long time; Rita summons Godzilla, thinks she can control him. Godzilla laughs and goes on a rampage anyway. Rangers think she controls Godzilla and attack him. Rita laughs. That was basically the second book, and only one I found...), its probably been done and likely published somewhere (possibly as Sentai Rangers or however you render that in Kanji script).
