Shiro Tokisada Amakusa (天草 四郎 時貞, Amakusa Shirō Tokisada) is a recurring boss and playable character in the Samurai Shodown series. He is based on the historical Amakusa Shirō Tokisada, who led a Christian rebellion in the Shimabara region of Japan where the bakufu army crushed his revolt and executed him. Though his portrayal bears similarities with the Amakusa in Makai Tensho, the developers haven't confirmed if he was particularly based on him. According to Gamest Mook, he was a possible candidate for the Samurai Shodown 64 lineup but was taken out due to time constraints.
Prior to to the events of Samurai Shodown, Amakusa is resurrected by the dark god Ambrosia; he uses the body of Shinzo Hattori (one of Hanzo's sons). His main plot involves him stealing the Palenke stone, which he intended to use to bring Ambrosia to the mortal world. The player prevents this from happening by defeating him. Upon his resurrection in Samurai Shodown IV, his spirit splits into two halves: one good and one evil. His evil counterpart is slain by Zankuro in the same game but his good side lives on thanks to Shinzo. During the events in Samurai Shodown II, he saves certain characters from Mizuki's wrath but is defeated, leaving only Shinzo's body for Hanzo to claim.
He's a mad and vengeful spirit, resurrected by Ambrosia as a being of destruction to put up a new world order. Once he is relieved of the dark god's possession, he reverts to his living persona as a kind and merciful soul. He is a narcissist by nature, which is what originally lured him to Ambrosia's temptations.
True to the historical Christian Amakusa, he speaks of sin, mercy and salvation, especially in later appearances.
- Levitation - Amakusa has the power to levitate his weapon and other characters off the ground.
- Teleport - Amakusa can teleport himself.
- Multiple Attacks: Amakusa can deliver several slaps at once.
- Fire Projectile: Amakusa has the ability to project a fiery image of a demon.
Amakusa fights his opponents by attacking them with a levitating gem. He can direct the gem with an impressive range, able to smash his enemies from the air and ground level from nearly any distance easily. At times, his gem may not compensate for opponents close to him so he also has a multi-hitting slap attack when he is close. To confuse his adversaries, he may also teleport and hover above them before diving upon them with a damaging attack. He also projects fiery projectiles in the image of demons to his foes, making him a formidable long-distance fighter.
