These four beings go by many names, Mr X, T-103, T-00, the Tyrant (with his $9000 trench coat) from Resident Evil 2. Alex Mercer, Zeus, The Prototype, from the Prototype games. General Grievous, The Knight Slayer, Qymaen jai Sheelal of Star Wars. BJ Blazkowicz III, the Doom Marine, the Doom Slayer of Doom Eternal. All four have ridiculous speed, strength, and unique abilities, but the one thing they all have in common, they all have brutal methods with which they are capable of completing their goals. They all have been brought to Equestria during the Storm King's invasion and will change history forever. Can they go beyond their brutal fighting instincts and embrace peace? Only time will tell.

(A five way crossover with Doom Eternal, Resident Evil, Star Wars and Prototype characters crossing over with My Little Pony the movie and going through season 8+9 and maybe beyond that.)
