Well how I see it:



Dr. Faust - Show up as a Draconequus. ( Making Six Mares vigilant for his presence ) Probadly fascinated for such strange world. Proofing his doctor skills on dangerous diseases and cure sick ponies. While Twilight question his methods. ( Maybe Faust make Fabulous Makeover Exhibition for Twilight. ) *Give Twilight fabulous eyebrows*



Chipp Zanuff - Ninja, who have ZERO idea, where he is at. straightforward and simple-minded man, impatient and quick-tempered. ( sounds like Rainbow Dash's stallion. ) x'3

Chipp beat King Sombra and name The Crystal Empire as "The Crystal Chipp Kingdom". x'''3 And he name himself as The president.



Axl Low - Very confused time traveller of British descent. Asking if their ruler, Princess Celestia could be so kind and send him back to his own world and possibly to the 20th century. Fight against The Changeling invasion at The Shining Armor/Cadence's wedding. ( Thanks to his strength, he was able to put an end to the invasion (with no casualties) ). Chrysalis find Axl as fascinating stallion. ( Chrysalis/I-no personality )



Zato-One - Woke up from the underworld in The everfree Forest with no memories. ( Except he remember "Millia" name. ) Zato save CMC from Timberwolves with his dark powers. Zato is taken to Twilight's home for hoping discover his past. ( with little success. ) Twilight sense dark magic on Zato and thinking him as King Sombra's puppet.



Potemkin - Not much to say his character. Perhaps Applejack's love interest. and thinkng him making "Heavenly Potemkin Buster" on Discord.



Millia Rage - Not much to say for her either.



Venom - *shrug*



Sin Kiske - would making friends and use his gear powers to strike down the evil.



Slayer - I dunno. Rarity would love his style.



Bedman - Certainly villain. Pulling his enemies into The Nighmare threater.
