Edward Phillipe Mott, "Roanoke"
Mott — at least the onscreen version of Mott (and his ghost) played by the actor Rory Monahan — was fun while he lasted, but that certainly wasn't very long. (A single episode, to be exact.)
Peters seemingly had a blast going full on foppish aristocrat with this character, and I guess it was cool that we got to see him make out with a dude instead of Taissa Farmiga, but we simply didn't get enough time to get to know him. And we certainly didn't get enough time to justify a higher placement on this list.
Jimmy Darling, "Freak Show"
That "Freak Show" is my least favorite season of "AHS" is not Peters' fault, but it does affect how I feel about Jimmy Darling, the dude with the lady-pleasuring lobster hands.
I was initially excited about the season when it seemed like it would be the story of a group of so-called freaks struggling to survive in a judgmental town while also being blamed for psycho clown murders, but then Twisty died in the dumbest twist ever, and Jimmy's arc suffered because of it. Basically, instead of Jimmy being the noble leader of a group of misfits on a quest against hatred, the show made him a mopey dude with daddy issues and, like, 17 love interests.
Rory Monahan, "Roanoke"
I'm so, so sad that Rory died after only one episode, because he instantly resonated as Peters' most hilarious character on the series to date (and if you've seen him in the "X-Men" movies, you know the man is comedy gold). After years of watching Peters play emotionally damaged murderers, it was a thrill to see him take on a douchebag comedic foil ... until he got disemboweled by pesky ghosts and disappeared forever 30-some minutes after his introduction. Drats.
I've got to be honest, here: the amount that "AHS" fans continue to romanticize the character of Tate, who was violent and manipulative to everyone, and specifically abusive to Farmiga's character Violet, concerns me. (Literally, the season finale ended on a joyous note when she forever banished his ghost from interacting with hers.) Also, the school shooting sequence set to badass, Tarantino-esque music and clearly based on the very real Columbine shootings was in shockingly poor taste (something that is Ryan Murphy's fault, not Peters'); I turned off my TV when it aired feeling physically ill, and have never watched that episode since.
However, it's also the role that introduced us to Peters, and if I look at Tate as a fascinating, complex pseudo-villain instead of as a romantic hero, I begin to get the hype.
James Patrick March, "Hotel"
Peters seemed to be having the time of his life playing March, and was consistently "fun" to watch — fun in quotes because a whole lot of brutal murder doesn't float everyone's boat — even if the rest of "Hotel" was a bit of a mess. This was the role that let "AHS" fans know Peters is capable of playing more than a brooding romantic lead, and hopefully future seasons will follow "Hotel" and "Roanoke"'s lead and let the man camp it up a little.
"Asylum" is the best season of "AHS" to date, and Kit Walker Peters' most fully developed character. Through his tragic romantic relationships with Alma and Grace and his friendships with both Sarah Paulson's Lana Winters and Jessica Lange's Sister Jude, we got to fully know Kit as a kind, sensitive, and incredibly heroic leading man.
Sure, playing a classic hero type doesn't seem to be the quirky Peters' bread and butter at this point in his career, but rewatching Kit scenes is a firm reminder of how good the actor can be when his work is understated.
