Which character from Kamen Rider/Super Sentai do you despises the most?
 

The one you personally cannot stand and just want them to go away.

For me, it would be Takaharu Igasaki from Ninninger. (I used to hate Daigo but Takaharu take the cake as the red ranger that I despise the most)

Everytime I heard him yelling "I'm getting fired uuuuppp!!!", it make me want to hit my head so many time and he came off as an arrogant prick who think he’s better than anyone and in fact, the show focus way too much on him that none of other Ninningers got their own character development and even if they got their own episodes, Takaharu have to be important somehow and they end up as second banana to him.

Takaharu is the reason why I prefer a more serious and calm Red Ranger like Takeru Shiba from Shinkenger, Captain Marvelous from Gokaiger and Yamato Kazakiri from Zyuohger.

So yeah, Takaharu Igasaki is the one character that I personally despises the most. (I drop the show around the fifth episode because I just couldn't stand at Takaharu)

Is there’s character from Kamen Rider or Super Sentai you personally despises like the infamous Masato Kusaka from Faiz cause let’s be honest, you not going to find Kusaka on anyone’s top 10 favorite Kamen Riders. (I would be surprised to if someone did put him on their top 10 favorite Kamen Riders considered he’s not very popular among the fanbase.... well at least for Western audience)

Onari. There are very few characters in any form of media that I hate as much as Onari.

Tsukasa is probably one of my least favorite lead riders.

I seem to be in the minority that doesn't hate Ghost all that much, but Takeru annoys me so much, because a big part of what was wrong with Ghost is that it had the most boring main Rider I've ever seen (granted, I've only seen from W to Build, and Zero-One). He's a wholesome sweet guy who just wants to help everyone be happy, and that's fine, but that's all there is to him. He doesn't have struggles with going too far like Eiji, or inspiring passion like Gentaro, or an aggressive side like Emu, or a dark past like Sento, or a dream for the future like Aruto. And it's such a shame because his situation of having a countdown too his death was so interesting and the writers could have gotten such good characterization out of it, but instead he gets no growth, no complexity, nothing. The only other main Ride I can think of who's as static is Haruto, and at least Haruto had style.

I wish he had been a worried hero, one who wasn't sure if he was up to the challenge and had to deal with the fear of knowing what was at stake, until eventually overcoming his doubts so that his "I believe in myself" catchphrase actually carried weight. There were a couple hints of that, but IIRC nothing ever came of it, he just moped invisibly for like half an episode and then was suddenly all better.

The characters I despised are:

Kamen Rider: Tsukasa Kadoya/Decade Rider
Super Sentai: Koh/RyusoulRed (no, not Koh/Kou of the Howling New Star/KibaRanger. He's a very good man now.)

Gou/Kamen Rider Mach. He was an absolute asshole to everyone, until the last minute. I despise him so much.

Geiz is a close second, and depending on the day, overtakes Gou.

For Rider it's probably Onari. Although having watched so much of it I would assume there's someone I disliked more but managed to forget. Onari on the other hand I still hate with a passion.

For Sentai, having watched only very little over the years, it's Lucky. Just an all around terrible and annoying ass character. And he was the lead too... man Kyuranger sucked so much.

If there’s a character in Rider, it would be Ren/Kamen Rider Knight. For Sentai, it would be Keichiro/PatrenIchigou.

Otoya Kurenai. Without him, I would merely have disliked Kiva a lot. With him it became the only Tokusatsu show I've seen that I actively hate.

Noel from LuPat makes the show worse by his very prescence, so there's your Sentai answer.

Kamen Rider, I disliked Mach for a while, but he did eventually redeem himself, so I can't hate on him anymore. Other than that, I've not hated anyone in the show's I've seen that I wasn't obviously meant to by the writing.
