I had a idea for a fanfic where Angron goes to Equestria after his fight with the Lion. There he is free from the Nails and becomes a hero. Don’t know if I should make them ponies or anthro tho, no humans, never like humans in MLP

The idea is that, when Angron is defeated, Vashtorr activates Wyrmwood, causing a Warp anomaly that sends Angron’s soul to Equestria. On the way, he has a vision of Big E.
Upon arriving, he fights some monsters, has a nightmare that leads Luna to investigate what happened, only to be surprised and warn Celestia and the Mane Six about what occurred. After some events, the Mane Six and Angron finally meet, have some adventures together, meet the princesses, more chaos ensues (maybe something related to Discord), and everyone has a vision of the fields of dead gladiators of Nuceria, where a sad and dramatic scene similar to that in the book Betrayer takes place, in which Angron delivers that heart wrenching speech.
And then other things happen, like him going on adventures with the Mane Six. I don’t know if I should make the story before or after the 3rd season, because I had the idea of ​​Angron fighting a overpowered Tirek who managed to defeat Twilight and steal all her magic. The two would have an epic battle, and Angron would die with all the Mane Six and the princesses around him trying to save him, until an aspect of the Emperor would appear in alicorn form and revive Angron, freeing him from the Nails, and the two would then have a sincere conversation for the first time.
Then some slice of life stuff happens, and Angron is finally able to recover and become a new hero in Equestria.
