Plot: This is the story where both Batman, Iron Man, Green Lantern, & War Machine were somehow isekai'd in another world (And they not only de-aged but they look like other anime characters) to save all of humanity alongside all of their suits, gears, etc. Will they prevail as an unknown & unmasked trio of saviours to get back home or will they die trying?

Also, all things in this novel doesn't belong to me because this is all for entertainment purposes.
