Mr. Robotube is the mascot of MiniVisions Inc., which is a subsidiary of Choice Provisions and is responsible for the arcade-style game Woah, Dave!. He appears as an ally in BIT.TRIP FATE, replacing Radbot.
History[]
RUNNER/RERUNNER[]
Mr. Robotube does not appear in-person in RUNNER and instead appears as Radbot, in RERUNNER he appears on a graffiti in TRIUMPH.
FATE[]
Mr. Robotube is revealed to have been piloting Radbot in "Pursuit" where Radbot explodes, releasing Mr. Robotube.
In the gameplay, Mr. Robotube acts as a power-up. He alters CommanderVideo's bullet spread into a sine wave/double helix pattern that can pierce through both enemies and walls. In addition, the bullets possess an exceptionally high damage boost, the highest in the game. In GIGA, a third, straight beam is added to the middle, further increasing the coverage and accuracy. Because of these traits, Mr. Robotube is easily the most powerful power-up in the game, and the second favorite of the player base, behind Meat Boy, if only because of the latter's ability to destroy enemy projectiles.

FLUX[]
Mr. Robotube appears as a figment in CommanderVideo's ethereal plane. He takes the form of a light blue square. And he, alongside Meat Boy, Junior Melchkin, and CommandgirlVideo slowly drift away as CommanderVideo sinks into the afterlife before vanishing entirely from his consciousness.
Runner2[]
Mr. Robotube appears once more as Radbot in this game's opening and closing cinematics. This can be inferred given the game's placement between RUNNER and FATE.
Runner3[]
Radbot reappears in Runner3, but due to its dubious timeline placement and non-canon nature, it's unknown if he's still being piloted by Robotube. Mr. Robotube himself makes a couple cameos as graffiti in some of the game's Retro Challenges.
