A member of the Lost Temple. After Infernal and Medkit—who were like older brothers to him at Crossroads—suddenly vanished one day, he began roaming Crossroads with his only best friend, Rocket, to find them. However, things didn't go as planned. While sneaking around Crossroads late at night behind the back of his adoptive father, the SFOTH God Venomshank, he encountered his cousin, the SFOTH God Darkheart. He was then teleported to the Lost Temple(?) region where Medkit was reportedly spotted. Many figures passed him by during that transition. Teleported to a burning desert amusement park by Darkheart, Sword learned that the Lost Temple was destroyed and recreated by a God, and is now burning eternally due to that God's wrath. While Infernals are genderless, Sword is characterized by his masculine, chivalrous demeanor. He features red demonic horns, white skin, and a sword-cut scar on the right side of his face. He is energetic, careless, and unfortunately lacks intelligence, which leaves him with no friends. He lives in Crossroads, a plaza-like area that is relatively comfortable for Infernals to inhabit. However, he currently seems unable to return due to Darkheart. He wears leather-strapped boots, a red sleeveless shirt, brown leather gloves, shoulder armor on his left side, and a gray cloak. Because his gear is quite old-fashioned, he has been mocked with comments like "Is that a costume?" He is positive about everything every day and has a slight mischievous streak. Infernals each have their own primary weapon, whether related to support or offense. Sword can summon a sword, an offensive weapon.

One of the seven SFOTH Gods in the Phighting universe, representing the Darkheart sword. He is arrogant, relaxed, and a God whose ultimate thoughts remain a complete mystery. He appears to be Venomshank's younger neighbor or perhaps a cousin. Though there is some distance between them, he is definitely Sword's cousin. He is based on the "Darkheart" item created by Roblox's Shedletsky. He seems to have a bickering relationship with Venomshank. Darkheart has feigned innocence, claiming he doesn't understand why Venomshank is so overprotective of Sword. He wears a green and black witch hat that hides his eyes and always wears an unsettling smile. He has black, featherless bone-like wings—likely just one. Darkheart's power is stronger than one might expect, but he seems to use it for pranks rather than for ruling or management. TMI: He enjoys fishing.
