Toast Busters is the superhero form of Toasty, the son of Johnny Toast. He first appears in "Excalibur: A Starbuggers Production" (Known on the wiki as "Venturiantale in Space: The Final Frontier"). He wears a black outfit with a large, staggered "TB" marking on the chest, blue stripes on the sleeves and his gloves, and has a red cape. It is possible he has some relation to PIE - He even has his own song.
Originally a take on Buck Rogers, Toast Busters' name originally had no "s" on the end, and was later changed to Toast Burner. However, after a Venturiantale-based take on the Ghostbusters song was posted on YouTube, it reverted to Toast Busters, his original name with the added "s".
Role in "Excalibur: A Starbuggers Production"
Toasty is first seen investigating the wreck of the USS Italian, which has crashed following the events of "L4D Space Adventure Mod!". Later, he is watching a space battle between Captain Maloney and Mari Tann vs. Khoin (who now has skin) near a Dalek Battlestation from the USS Excalibur when he sees some rockets, which are Gmod thrusters with gasoline tanks on top, leaning against the wall of his quarters, reminding him that he is in fact Toast Busters, and he transforms into his superhero form and straps on a rocket, though his rocket explodes. He straps on another, but it explodes as well. He straps on a third, but this one explodes too. He then stares angrily at a fourth rocket, which also explodes. Finally, he gets into space, now wearing a new outfit and with a working rocket, which he points at while saying, "It helps if you don't say the name."
Toast Busters then proceeds to neutralize the Dalek Battlestation, but gets crushed between two Tesla Coils when he tries to absorb their energy (pulling them out of their mounts) in the process. A third Coil zaps him, causing a massive explosion that leads to his mouth becoming detached from his face. He then gets an idea - and flings his mouth like a Frisbee into the center needle of the station's laser emitter, which is about to fire. He then uses his mouth is able to destroy the station by holding back its energy, which he does by simply taking a deep breath and holding it.
He then transforms back into Toasty and regains his mouth before heading back to his ship, but the exploding battlestation creates a temporal fissure; Daleks from the future arrive through the fissure and attack the fleet, and the Excalibur escapes destruction by going through the fissure. It is unknown what happened to him after this.
