When a warrior from another world combined with a legendary spirit comes to a different world from what he's used to and intervenes in the timeline of said world, one can only dream of what happens next. Only fate will decides what happens to him and the ones around him.

(I know that there are some Fairy Tail reacts to Death Battle, but they're either wrong death battles or fan made death battles) So, Natsu and Happy have broken into Lucy's house, again, but with Grey, Gajeel, Pantherlily, Erza, Wendy and Carla (and Juvia in the window). But they came because there was something in the guild, a box filled with dvd's. All to the same name "death battle"
