Hey, that makes two of us, although I do chuckle to many of Felix's jokes. Regardless, I hate him for being selfishly obsessed with strength to the point of being unreasonably harsh to his kind father. (I didn't yet reach Azure Moon's time skip, and I want to finish Azure Moon as blind as possible, so may people please avoid spoiling me on how Felix's "bond" with his father "develops"? Thank you.)
Also, because I hate profanity, I dislike/hate many characters whom cuss, and this tends to be common with characters from T-rated games that 8-4 localized. This includes Chrom, Echoes Alm, Echoes Celica, and Echoes Mila; don't get me started with Berkut and localized Sully! Speaking of Echoes Alm and Echoes Celica, because I hate public displays of love, their shamelessly lovey-dovey duo alt. in "Heroes" sealed my hatred for them. Also, for cursing, I dislike Edelgard, Claude, and pre-time-skip Dimitri and hate Yuri, Balthus, and time-skip Dimitri! Outside of Fire Emblem, I hate Remake Cloud, Remake Aerith, all members the playable main cast of Dragalia Lost except the two newest members (Don't spoil them without spoiler tags, please.), every character in Critical Role, seemingly every playable character in Persona 5, and more. These characters' foul mouths make me feel uncomfortable with witnessing them grow.
Plus, I tend to dislike characters with outfits that I dislike, and those outfits tend to be needlessly fan-servicey to me. For instance, I dislike Altena, Ayra, and Lachesis when they're in their "canon" outfits, but I love them when they're in outfits based on their original concept art. Also, I hate adult Tiki only because her stripper-like outfit contradicts her calmness and elegance, but I'd love her if her canon outfit was an elegant dress or even an outfit like Nagi's. However, I do love young Tiki; her fan-servicey outfit is okay to me. Generally though, I'm reluctant to like characters whose outfits don't match their personalities to me (Nowi).
Now, for Pokemon. I hate Pikachu for its overexposure. Its absence in the Unova Pokedex is partially why Gen. 5 is my favorite Gen. Also, I don't hate Cynthia or Zinnia, but I believe that they're overrated. In addition, I dislike Elesa when she's in her Black/White 2 outfit or her Sygna Suit, but I love her in her Black/White 1 outfit. Lastly, I didn't dislike Jasmine at first, but hearing her say "Darn" when she loses in Pokemon Masters made me squarely dislike her because that feels a little too "vulgar" for her character considering her other quotes throughout the series.
That's all for now.
