02Appearance
Urban Guerrilla is a well-built Rock Human, dressed in minimal clothing. He wears a set of bracers on his forearms and a pair of pants with three vents on the thighs and metal knee guards. Over Urban Guerrilla's head is a complex hood that features a breathing apparatus hooked into his mouth, along with goggles stylized with six-pronged eyelashes and a lens wiper on the left side.↗
However, when in public Urban Guerrilla assumes the appearance of a normal doctor in uniform, complete with glasses. He's also revealed to have short hair.↗
03Personality
Urban Guerrilla is an animalistic Rock Human, grunting and growling while speaking. When stalking his targets, he devises a "killing order" to select who he'll assassinate first based on their threat level. Urban Guerrilla also displays an intense and disturbing side when frustrated, stating to Rai Mamezuku that he'd take his time dismembering and mutilating Mamezuku's body. Despite his brutality, Urban Guerrilla is efficient in his work and intelligent; observing his enemies before attacking and making sure to take needed precautions.↗↗↗↗
Urban Guerrilla is disdainful of humans and dreams that one day the Rock Humans will stand above humanity, planning to use the new variety of the Locacaca to do so. Despite his specieist views towards human beings, he still praises Josuke as a "marvel of biology" due to Josuke's nature as a fusion between Josefumi Kujo and Yoshikage Kira.↗↗↗
As a doctor at TG University Hospital (specialist in gastrointestinal diseases), it can be inferred that Urban Guerrilla was bright enough to exercise his job or obtain his medical license by himself.↗↗
04Abilities
Stand
Urban Guerrilla's Stand Brain Storm is a multi-unit in the form of burr puzzles sent out from his hands. It mimics the effects of certain bacteria by melting the flesh of anyone touching it and creating holes in its victim's body.↗
05Story
SPOILERS
Background
Urban Guerrilla is a Rock Human who worked for the Locacaca Organization. In addition, he was working as a doctor in TG University Hospital specialized in gastrointestinal diseases and pretended to be "Ryo Shimosato, aged 38".↗
The Plant Appraiser
By riding on his pet Doremifasolati Do underground in areas with soil, Urban Guerrilla inconspicuously pursues Rai Mamezuku. Josuke and Yasuho also get involved when they meet the plant appraiser on a bus. The trio quickly abandons the bus and heads away from trees, causing Urban Guerrilla and Doremifasolati Do to be slowed down by the asphalt and concrete on the road.↗
Urban Guerrilla catches up to his prey at their "safe place" and Brain Storm attacks them from tree branches, melting holes in Mamezuku's left hand. While Yasuho runs toward the sixth pole of the ski-lift that Josuke and Mamezuku are on, Urban Guerrilla and Doremifasolati Do reveal themselves. He then grabs Yasuho's neck and sends Brain Storm into her body. However, Mamezuku uses Doggy Style and stabs Urban Guerrilla's shoulder with a knife, causing him to let go of Yasuho.↗
Rock Human and Rock Animal
Urban Guerrilla becomes furious over the increasing difficulty of capturing Mamezuku, yelling that he'll grotesquely maim his body once he's caught. He decides on a "killing order", choosing the best way to assassinate the trio based on their skill and powers. As he monologues, Mamezuku attacks Urban Guerrilla again with another knife. Guerrilla hides within Doremifasolati Do's body, with it serving as a shield.↗
As Doremifasolati Do chases Josuke and Yasuho underground, Urban Guerrilla secretly escapes and waits in ambush for Mamezuku to appear on the ski lift pole. He catches Mamezuku off guard and states Mamezuku is now the first on Guerrilla's "killing list", before sending Brain Storm across the cables and into Mamezuku's body. He states that the Locacaca is something the Rock Humans have known about for an incredibly long time.↗
Urban Guerrilla curses Mamezuku and turns his attention to Josuke after the latter chases after him. He hides within Doremifasolati Do's body once more and goes on the offensive, sending Brain Storm into Josuke's face. Guerrilla laments that Josuke's body is slowly breaking down, stating he is aware of the fusion between him and Yoshikage Kira. He praises Kira on cultivating the new breed of Locacaca and condemns Tamaki Damo for only seeking it to acquire riches.↗
Urban Guerrilla, realizing Josuke's plan urges Doremifasolati Do to dive faster. The fuel covers Doremifasolati Do as Josuke slips the fuel inside the Rock Animal's body via his soap bubbles. As Mamezuku drops a lit lighter into the hole, the fuel ignites and combusts; blowing both Urban Guerrilla and Doremifasolati Do into pieces.↗
