Character Creation / BiographyEdit

Oscar boomer

Left to Right: Oscar Johansson (creator) resembling himself to his character Boomer looking like a stick figure version of himself.

Boomer is one of the main charaters who has hair in the series, besides the Doctor out of all the stick figures in the series of Castle. The reason why he could have blonde hair is because Oscar Johansson (creator) has blonde hair. So technically he's making a stick figure version of himself in the series but this hasn' been confirmed at any point. Also its rumored Boomer is 19, according to Oscar's age (19) when he first created Boomer in Castle III Part A release. Boomer's long bangs hair could prove he's young indeed, and also due to his skills as a leader ending up being brutal (A Leader's Brutality) could mean he's too young to learn about leadership when he went to save those soldiers on the bridge. Although it's just speculation, none of this has been confirmed. Boomer is therefore the youngest member in the Elite Team (confirmed on his bio on the Castle page on DeletionQuality) which brings a more likely reason his age is 19.

Boomer is an demolition extremist in the elite team in the series. He uses a shotgun and explosives, sometimes follows the General's orders, but Lloyd, Etrius and Beecher don't follow the General's orders at all. Boomer saved soldiers from a collasping bridge, if you look after the credits of Castle III Part D, it shows an extra scene of boomer and his squad soldiers of how they ended up where they were in the Repercussions.


Castle III part AEdit

He was watching the helicopter land.

Castle III part BEdit

After getting ready for the mission he was walking to the helicopter with the others. As it went off they went to the third castle. When they landed in the courtyard he blew up a door so they could enter. After entering the castle they find the Altar room.

Castle III part CEdit

After entering the Altar room they are attacked by creatures. Boomer puts an explosive on one of the doors. As the floor begins to crack, Lloyd is stuck on the other side. They escape the room

Castle III part DEdit

Now on the bridge they decide to go back to the courtyard, but suddenly they are attacked by flying demons and creatures. One of the soldiers was able to bring one of the flying demons to crash on the bridge causing the bridge to break. He was on the side with three other soldiers, so they climbed down. After climbing down they find a soldier's dead body which fell off the bridge.

Castle Repercussions part D1Edit

move so they go down the corridor. After being attacked and losing one of their teammates they continue running away from the puppetmaster, they run into some creatures. After throwing a grenade into a hole in the ground, they escape by going through a crack in the wall. After that they have to go through a hall full of sleeping drones, but suddenly they wake up and start to attack them. After finding the exit with Roberts they lose Mullins.

Castle Repercussions part D2Edit

After escaping the drones, Boomer monologues to himself about the situation. Suddenly they are running from a black mist. They find the helicopter that has Ray, Plisskin and Mullins inside it. Boomer tells Plisskin to take off, but suddenly they are attacked by creatures, flying demons and a dragon. They ecsape the castle in the helicopter.


  • In Castle III part D, fans thought Boomer and his squad soldiers made it to the helicopter when the climbing scene went away or they thought that they died. But looking after the credits of Castle III part D, the answer is finally revealed. After the credits, it shows Boomer with a couple of soldiers seeing a dead soldier bleeding on the floor. One of them say: "Holy Shit" and his voice echoes. Another soldier asks Boomer: "Boomer, what are our orders?" and they stand still in the hallway and a creature makes a noise in the background. Then the scene fades away, knowing that they're trapped in the Castle which leads to their aftermath in D1/D2 of Castle Repercussions.
