- Rumble to Dipper

Rumble McSkirmish (Rudo Mcgolpes in Latin America version) is the main villain in the Gravity Falls episode Fight Fighters; a fictional fighting videogame character that was brought to life by Dipper Pines by inputting a secret code in an arcade.

History
Dipper found a secret code on the side of the Fight Fighters arcade. After inputting it, true to the paranormal nature of the town, the arcade flashed in an unexpected radiant light and a voice shouted: "SELECT YOUR CHARACTER!" Dipper mumbled "Rumble McSkirmish...?" as the fighter materialized in front of him. He saw this as an opportunity to have a chance in a fight he had gotten into with his love rival, Robbie. However, it turns back on him when he has to lie to Rumble with the only scenario that sets Rumble off (and quite possibly the only one he seems to understand due to his programming limitations): That Robbie had killed Dipper's father, this sets the pixellated fighter on a rampage in pursue of Robbie until he can "Finish him".

Dipper chases after him and a scared Robbie in an attempt to explain the situation to the videogame character, he finally corners it in the same place he was going to fight Robbie, just before Rumble delivers the finishing blow, Dipper intervenes and admits he had lie to Rumble, knowing that this would mean that he would have to fight him instead. Rumble feels betrayed and dishonored so he challenges Dipper instead, Dipper accepts, even after being told by Soos not to do it as he would get sacked easily. Rumble unleashes a series of videogame themed attacks, Dipper dodges most and even counters at some times but the videogame fighter proves too much for him and ends up getting trashed in a Super Ultra Mega ALpha Neo Prefix Combo. After Rumble won he finished off with his catchphrase, "Winners don't lose!" Dipper told him not to bet on it because as soon as he was over with his mission, the mandatory end game GAME OVER screen appeared, which scared him. He grieved his last as he was erased from reality.
