The Eleventh Doctor posed as a fellow conspirator. He nicknamed Fawkes "Guido" and assisted him in finding fuse wire which Fawkes had previously thrown over London Bridge to allay suspicion. The Doctor, for his part, wanted to learn about the involvement of the Rutan known as Lady Winters and for history to proceed according to its known course.
Fawkes was trapped in a locked room filled with barrels of gunpowder beneath Parliament. He lit five of them in another room to launch Lady Winters' Rutan ship as the Doctor briefly put Parliament safely in orbit. When he attempted to set off the remaining thirty-six, King James' men captured him. (GAME: The Gunpowder Plot)
Another account suggests that after the collapse of the plot, Robert Catesby and Sir Thomas Percy fled to Holbech House in Staffordshire. They were shot and killed by the Sheriff of Worcester's men. Also killed was the genuine Guy Fawkes. The presence of the First Doctor and his companions had altered history so Fawkes died a year early. Sir Robert Cecil, King James' chief minister, immediately seized upon the political opportunity inherent in a dead Fawkes. He fingered his political rival, Robert Hay, as Fawkes, allowing for Hay's execution under Fawkes' name the next year. History thus healed itself. (PROSE: The Plotters)
His failure was celebrated yearly on Bonfire Night, when effigies of him were burned. During one of these celebrations, an alien animated the dummies to attack the crowd. Following the death of the alien, they returned to normal. (PROSE: The Night After Hallowe'en)
