Backstory: Nate Tennyson is one of the siblings of Ben Tennyson, but he went missing and nobody heard news about him. But the truth is that Nate was captured along with his friend Kevin Whiterose, and turned into a kaijin. Sensing his potential, Dormammu killed the ones who experimented on him and recruited him for his Chaos Avengers under the name "Shadow Moon". He formed a nice friendship with Jonathan Vincent, also known as Kamen Rider Orga. Their friendship grew to the point they agreed to save Colonel and Iris from their execution, leading them to be branded as traitors. Wong, who became the Sorcerer Supreme, rewarded him, giving him a new form, making him Kamen Rider Shadowmoon. He was then recruited by Eiichiro Hyoudou along with Iris, Colonel and Horobi to be part of his team and wipe out both Supernatural and Issei-Verse. Nate accepted the offer as he starts a new journey of redemption.

Quotes:

"I was born powerless, just like you guys. I'm feeling the same kind of anger! If we stay quiet, this hate will continue and we will be crushed. That's why you should be even angrier! This world is not just for those with power. This is also our world! So we have no choice but to fight."

"Humans have extinguished inferior species before, and by succeeding in such acts they have thrived. We should learn from them."
