Death's touch: Death's touch is exactly what it's named-- death by a single touch from at least one finger. Kaido doesn't use this ability unless all else fails. The reason for this is because every time he uses this ability, he loses a great amount of strength and energy, putting him at risk of his own death if used more than 9 times in one go. That being said, he mainly resorts to his other abilities, which is his dimension tentacles and scythe.
Dimension tentacles: Kaido developed this ability when he was 11 years old, and has had them now for 6 years. Kaido and the tentacles are mentally connected, meaning they can hear, see and feel the same thing almost simultaneously. This can be both good and bad, as it can become a weakness and a threat to him. Kaido can spawn multiple tentacles within a one mile radius, which can make him dangerous at times. The tentacles can spawn in any kind of shape, size, and even form. This means that they can also have weapon-like features. The tentacles are also like close companions to Kaido, since for most of his life he hadn't had anyone to talk to or look up to due to isolation and lack of trust and fondness to humanity.
Scythe: The scythe is Kaido's most commonly used weapon. He will bring this up before using his other two abilities. This attack has no negative effect on Kaido, but is able to break if hit with a hard enough force. When this happens, it will take up to two hours for the scythe to repair itself before being used again.
Backstory: Kaido was the first successful experiment made by Life and Death in the holy realm(past-life/after-life), but was thrown out to the grounder's realm(earth) at the age of nine due to Kaido's, or at this time Atreyu's actions pushing Death past his breaking point. This led to the deprivation of his wings, meaning he can no longer fly. Since he had been training to become the next grim reaper, he continued his training up to now, where he uses his skills for assassination but now hides his skill and ability in order to not get caught. Because of his training, Kaido is a strong and well-built man. He now rides a Suzuki Hayabusa motorcycle to get around rather than walking.
Combat info: Kaido is very good with close ranged attacks, along with dodging far ranged attacks and blocking the close ranged attacks. However, he cannot dodge or block forever. He can take hits when caught off guard, which would be when he is mainly focused on all but one thing or is caught in his blind spot.
Weakness(es): Kaido is missing his right eye, which serves as a disadvantage to him in combat since he has to act twice as fast to defend himself and fight off enemies. His abilities can also serve as major weaknesses, as found from above his backstory. As well as that, he can be caught off guard very easily when in the right situation or position. This can be when he or his emotions may be manipulated or are manipulatable, when he's being tricked or falling into a trap, or when he is unable to use his abilities.
Likes: food, head rubs, topics on vehicles/mechanics, getting his job done right(assassination), being with any close friends, being alone or with company when he needs/wants, cats, bugs/arachnids, a clean space, playing the electric guitar, singing/screaming his head off in a song, alcohol
Dislikes: incomplete tasks, filthy spaces, society, being in the spotlight, not having his Jack Daniel's after a long day
Fears: small/cramped spaces, losing those he cares about, having trust broken, becoming like his father who abused him in his past life
Things to know: Kaido has minor anxiety due to what he'd experienced in his childhood. Because of this, he's grown up mentally to be more of an adult rather than a normal teenager. With this, he will not tolerate anyone's bullshit and will outright ignore you if you give him such. Though he can be harsh when first met, he's a sweetheart when you get to know him well enough. And as a bonus or two, Kaido has a tattoo on his back circling near his neck down his back to form what look like black wings to cover up his scar where his real wings would've been. He also has expensive taste in clothing, and will not think twice before wearing warm clothes on a summer day.
