Shingetsu

Shingetsu (シンゲツ) is the clan leader of the Space Demon Clan Kamui Tribe, and the sworn enemy and rival to the main protagonist, Goro Izumi in Metroid: Kamen Rider Generations Vol. 3: Fates Intertwined.

Personality
Shingetsu regularly disdains and resents Goro's interferences with his clan's affairs, often fleeing instead of further justifying or persuading him of the Kamui Tribe's sincerity. Despite his affably evil traits, Shingetsu is a firm believer of Social Darwinism, he believes that the weak must be purged from the universe to make way for those who have the power to dominate over those he deems inferior; which explains the reason why Shingetsu wants to claim the for his personal glory, believing that he has the right to use its power to rule over all. Shingetsu treats everything as a game, especially involving his conquest of several planets across the galaxy; as shown that he reveals that he sent demons to attack humans for amusement. As the ruthless clan leader of the Kamui Tribe, he tolerates no failure and he's willing to dispose those who failed him if necessary.

Shingetsu takes his Social Darwinist mindset to extremes, to the point he develops a vindictive, misanthropic hatred towards humanity and views them as inferior and weak species, as well its idiosyncracies of hatred, evil, and conflict. He has no qualms about killing without prior incentive or knowledge, one such example when he kills a Smash that was sent by Night Rogue to stall him, Shingetsu immediately destroys that particular monster and at the same time killing the human who was forced to assume its form.
