Akuji Jashin/Dark and Evil Riders/Ultraman Dark Zagi/Dark Lucifer

"A Y/n in this world? Did you get betrayed? Cheated? Abused? Looking at your condition... you're okay. Hmm, that's a first. But that won't stop me from conquering this world. You can try, but I've been fighting versions like you! It will end the same way!"

Hundred

Giants of Darkness (Later Ally)

Dark Ultra Brother

Kamen Rider Yongo

"So you're the Ultra-Rider? Hmm... you don't look tough... But I won't underestimate my opponent just yet... But I did hear you defeated many people from the faction... Heh... time to test that! Now feel my power... Time to enjoy your hell!!"

Asmodeus

"Maybe I failed my first time to erase the heroes from existence... But this time, I won't fail! Because Kamen Rider and Super Sentai don't need a story! And the world doesn't need a hero!"

Amadum

"Kamen Riders, the heroes of justice? NO! NO! NO! NO! Kamen Riders should be evil! Not protecting humanity! Half of the Kamen Riders have evil powers! They should be evil, not heroes of justice! I guess I'll take it into my own hands to change that!"

Doras

"Kill... Destroy... Ultra Rider... and his... friends..."

DCD Monsters

Evil Jaune Arc/Ultraman Shadow/KR Fake Blade

"I got betrayed, hated, cheated... And why are you roasting me? Don't you feel bad for me? You should feel bad for me... My whole life, I've been suffering! And you're just making fun of me?!"

Evil Issei Hyoudou/Evil Trigger/KR Mirage Agito

"Would you stop making fun of me! My story is sad! Because of my so-called harem... friends... I became this! Don't you have emotions?! If you did, you would feel bad for me... That's why I have to kill everyone in the multiverse!"

Raul Evans/Kamen Rider Yuuki

"Don't you realize?! I try to save the world from corruption and this is my revenge that I wanted! I won't let anyone ruin my revenge even from you!"

Keyaru (Keyarga)/Kamen Rider Solomon

"All the time I will get revenge on those who have wrong me! And I use my healing and power of God to rewrite this world including my harem's memory and make them into my slave! I am the God! Kneel before me!"

Niro Kirukawa/Kamen Rider X-Geats

"Ichika... Why did you have to reject me?! I'm better! Stronger! I am better! Why do you like that guy instead of me?! Tch... If I can't have you, no one can!"

Mirror Riders

Armored Rider

Basco Ta Jolokia (Later Ally)

"Oh? You're the Metal Sentai? That means you're Marvelous' successor, right? Perfect... If I can't get my revenge on him, then defeating you will be enough for me!"

Jugglus Juggler (Later Ally)

"So we finally meet, Orb's successor! Or the next Orb? You know, that isn't important yet. I have something to deal with first, and that's you! Don't take this personally, kid..."

Stacy/Stacaesar (Later Ally)

"I really hope you don't talk or sing like that stupid golden pirate. This world is a real mess... so it needs to be scrapped!"

Racules Husty/Ohkuwagata-Ohger (Later Ally)

"Your laugh... It really reminds me of my brother. That's why... I'll defeat you so I can stop hearing that stupid laugh!"
