Giff

Giff appeared in 2022 TV series called Kamen Rider Revice. Giff (ギフ, Gifu) is the main antagonist of Kamen Rider Revice. He is the mysterious progenitor and ruler of the demon race worshipped by the Deadmans who were instrumental in his revival. Residing in his personal domain, his failed attempt at using Hideo Akaishi as a mediator for humanity resulted in his desire to erase all of humanity except for the sole Igarashi family, whose members carry his genes.

Giff is an alien that feeds on the malicious energy radiating from organisms. Amazed by mankind's ability to give birth to such energy en masse, several millennia ago, Giff arrived on Earth and wished to co-exist with them. However as time passed, the many civilizations that rose and fell, all viewed Giff as a non-benevolent devil. One of them was an ancient prosperous civilization that was annihilated overnight for opposing him, leaving only their leader, Hideo Akaishi, behind. Before Giff could do the same with the rest of mankind, Akaishi convinced him to let him be the mediator between both races. Giff formed a contact with him, granting him immortality before entering a long slumber. Although Giff was still in his dormant state by 1971, he had determined that humanity had evolved to the point that their evil would cause them to destroy themselves. In order to protect his food supply, he arranged it so that he would be found by a team of South American archeologists, preparing for his own awakening.

Being deemed an "OOPArt" (out-of-place artifact) after nothing could be deciphered from it, scientists initially began studying Giff intensively for the purpose of world peace, but organizations such as NOAH desired to weaponize him instead which led to the creation of the Vistamps. After Masumi Karizaki created the powerful yet lethal Vail Driver, its prime candidate Junpei Shiranami received a DNA transplant from Giff to bypass the lethality, however his future children: Ikki, Daiji, and Sakura Igarashi would also unknowingly receive Giff's DNA as well, essentially making them Giff's descendants.

Following the fall of NOAH, Giff's coffined state was stolen by Akaishi who worshipped it as the leader of the Deadmans. The cult also sought out Giff's relative Diablo to help progress Giff's revival, but he was destroyed following his own standalone plans to take over the world for himself, though this still had a positive reaction to Giff which was a sign that his revival was imminent. Though Orteca told Aguilera that Giff's revival requires six sacrifices, it actually only needed one which was her. During the process to fully revive Giff, the Deadmans Base was destroyed by Ikki Igarashi, thus halting the process but not restarting it due to both Amahiko Haitani and Yasushi Kudo having been absorbed. Giff's coffin is then seized by Fenix who continue to research it under the direction of George Karizaki and Akemi Mikoshiba.

With Giff's stamp in the possession of Orteca, the Gifftarians are then unleashed into the public, with each defeat fueling Giff's revival due to the creation of each requiring one human sacrifice. With his revival imminent, the warning signs are seen with the negative effects having spilled over Vice, Lovekov, and Kagero. Eventually, Giff's coffin became sentient enough to consume humans on its own. After his influence over Vice is temporarily halted with the creation of Jack Revice, the continued energy absorptions make the latter go out of control on its fellow Riders. In the midst of Jack Revice's rampage, Orteca fuses with Giff to acheive Phase 4 in the hopes of surpassing the devil himself, but is defeated by the new Kamen Rider Revice.

With his revival having been completed, Orteca is then absorbed while Giff sheds his coffin remains off revealing his true form. From then, he lies in his own personal domain with his victims floating around in cocoons. He had communicated with Akaishi to destroy the Fenix Skybase and several parts of the city while fighting the Riders. Ultimately after Akaishi falls, Giff's attempt to form a new contract with Daiji instead fails as he pulls Vice into his personal domain. He revealed his intent to destroy all of humanity except for his own family, the Igarashi family, who shared his DNA to Vice. However thanks to Daiji having regained Kagero and his balance of righteousness, EvilytyLive and Ultimate Revice are able to seal Giff back into his own domain temporarily.

Although much is not known about Giff's personality, he is shown to be ruthless and unsympathetic towards his enemies. This lack of sympathy even extends towards most of the Deadmans, as he devoured Orteca and rejected Aguilera with a slap to the face. The only exception is Hideo Akaishi, his loyal contract holder and servant, showing that he expects complete obedience, as Orteca allied with him to take his power, and Aguilera chose to become a Deadman when she was meant to be his vessel. For some reasons, Giff prefers avoiding direct combat unless necessary, usually having his underlings to do the work for him while he retreats to his own realm.

Powers and Abilities[]

Coffin[]

Vibration Emission: Giff's coffin constantly emits heartbeat-like vibrations that become more powerful as he comes closer to his reawakening. After the failed Gifftex ritual, these vibrations caused the Deadmans Base to rise from the ground as a flying saucer.
- Demon Influence: Giff's vibrations initially only caused headaches in nearby demons. As Giff nears his awakening, the vibrations begin to cause humans' inner demons to to become more aggressive even over long distances. Even an inner demon that was previously docile or well-suppressed by the host could become uncontrollable.
Selection (選択, Sentaku): A ritual through which Giff choses humans to become Gifftex. In the ritual, a candidate is presented in front of Giff's coffin.
