Your sentence to torture is now repealed! Now! Immediately! You are to be executed!

—Mike O.

Mike O. (マイク・オー Maiku Ō) is a minor antagonist and Stand user featured in Steel Ball Run.

He is President Funny Valentine's personal bodyguard. When Lucy Steel and Hot Pants infiltrate the President's residence in Chicago, he battles Hot Pants in order to protect Valentine. Mike O. is a Stand User and creates deadly metal balloons through his Tubular Bells.


Mike O. is a dark-skinned man of average to above-average height and medium build. His head is shaved save for a dark, curly patch on his crown; and centered on the edges of both eyes, extending to mid-forehead and covering his cheekbones, he has painted or tattooed a light, swerving design tapering at both ends into a spiral.

He wears a heavy overcoat of a thick collar and a sort of thick braid lining the length of his torso; a neatly folded scarf, and pants covered regularly by short spikes.


He is well trusted by the President. Like Blackmore, he is highly dedicated to his job, as shown when he finds the First Lady's corpse, crying in anger at having failed in his duty as a bodyguard.

From the way he conducts his investigation and his attitude during his fight with Hot Pants, he seems to be very intelligent, capable of combining his Stand and surrounding objects to create deadly weapons and strategies.


Main article: Tubular Bells

Mike O.'s Stand is Tubular Bells, with which he blows balloon animals out of metal (often long, iron nails), gaining a life to track and/or invade the body of a target; exploding and reverting suddenly to their metallic form.


Mike O. makes his first appearance when his principles decides it is time for Diego Brando to reveal the traitor's identity. The president gives him the task to track down and kill the intruder who was helped by Mountain Tim, and Mike proceeds by using his Stand powers to create a little group of balloon-dogs. These dogs memorize the intruder's scent and hide in the President's bedroom to protect him.

After a confrontation with Scarlet Valentine and the insidious balloon-dogs, Lucy barely manages to steal the President's corpse parts and survive. Mike, who perceived the explosion of his dogs, tries to figure out what happened, when Hot Pants appears to save Lucy. Once attacked, he uses his Stand to turn the tin shutters into flying explosive swans and the shutter themselves into flying deadly guillotines. By using this trick, he manages to amputate Hot Pants arm before her Cream Starter could reach him.

Attempting a final blow, Mike misses his target, revealing the presence of Lucy and (to his shock) the dead body of Scarlet Valentine. Furious because he couldn't manage to protect the first lady, he loses his mind and blows into his needles to prepare his last attack. It is now that Hot Pants reveals to have used her flesh spray to throw tiny meat particles and put them into Mike's lungs. He ends up accidentally killing himself when his lungs are filled with too much air and explode.
