Killbus

"This planet... this universe... I will destroy it all!"

- Killbus

Killbus is the king of the Blood Tribe and the main antagonist of the Kamen Rider Build NEW WORLD: Kamen Rider Cross-Z V-Cinema movie. He is the older brother of Evolt who comes to Earth following his brother's demise in search of Ryuga Banjou.

Killbus is voiced by Anri Katsu. As Satoshi Kakizaki, he is portrayed by Gaku Shindo, who is best known for his role as Sid Bamick/Special Duty Officer Barizorg from Kaizoku Sentai Gokaiger.

History
The King of the Blood Tribe, Killbus' lust for destruction led him to destroy Planet Blood, the homeworld of the Blood Tribe, and send out the remaining members to destroy and consume more planets.

After the World of Build was merged with the main Kamen Rider world to create a new world, Killbus arrived in the new world and copies the form of dancer Satoshi Kakizaki, planning to restore the energy of the Pandora Box and use it to destroy the entire universe. Taking a Build Driver from Sento Kiryu, Killbus obtains the means to transform into his Kamen Rider form, Kamen Rider Killbus, which is even stronger than Kamen Rider Evol. Evolt, Killbus' younger brother, also returned but allied with the Kamen Riders against his brother to prevent him from destroying the universe and save his own life.

Personality
Like the others from the Blood Tribe, Killbus is cruel, deadly and destructive. However, in contrast to his younger brother Evolt, Killbus is less concerned with obtaining more power and more with just causing destruction, with his brother describing him as a "hedonist who loves to destroy". One trait Killbus does appear to share with Evolt is a casual and faux friendly demeanor that juxtaposes alongside his sadism, with Killbus greeting Ryuga and joking that he's been "dying to meet [him]" in their first encounter.
