I'm looking for a story about Where this boy lands into a anthro Equistria after he died from a car accident (I think) he was given a new body by faust. When he wakes up he got a bottle with a liquid that when he drinks, gets him the powers of his DBZ OC. He drinks it to save the CMC from a manticore. he does more heroic deeds and even transforms into a Super Kaio-ken form while he fights discord.

Shit bet I have that one saved I just gotta see if I can't find it

It might be this but I haven't read it in a bit so I could be wrong but it's the only one that I found had a similar start kid gets hit by truck ends up in eques so I'm pretty sure it's this one

The One you where looking for was the four starred hero by wurkywilk but I think he deleted the previous version and is now doing a Revamp.
