Rufus is the deuteragonist in the Bill & Ted franchise. He is the time-travelling mentor of Bill & Ted. Rufus hailed from the idyllic future of 2688 A.D.
He is portrayed by the late George Carlin.
Rufus uses a time-traveling phone booth to travel back to 1988, 700 years ago. His mission: to make sure that the Two Great Ones (Bill Preston and Theodore "Ted" Logan) remain together to form the band "Wyld Stallyns", whose music will become the core of the future's Utopian society. Rufus finds that Bill and Ted are on the verge of failing their high school history class, and, should Ted fail, his father, Police Captain Logan will ship him off to an Alaska military academy, effectively ending the pair's dreams of forming a band. As the two try to write a history report by asking customers questions at a local The Circle K, Rufus introduces himself to them. Though Bill and Ted are sceptical of Rufus' claims, they are convinced when future versions of themselves land nearby and explain the situation to them. Rufus reveals to Bill and Ted the secrets of the Circuits of History, which can transport the user anywhere in time. Their first stop: Austria, in the year 1805 and Napoleon Bonaparte, who is preparing to lead his French Imperial Forces into battle. Returning to the present, Rufus leaves the two with the phone booth, stating that Bill and Ted will be able to travel anyplace in time, but only "as long as you remember this: no matter what happens, you must get to that report."
He encountered the duo again when they ended up returning on the previous day outside the Circle K with Rufus introducing himself to their past selves. Bill and Ted recount their experience to their past selves, and learn how to properly return to the present from Rufus in order to give their history report on time.
After successfully completing their history report Rufus joined Bill and Ted as they practice and congratulates them on their report. Rufus brings in Princesses Elizabeth and Joanna, whom he rescued from their father (and from getting married "to those royal ugly dudes"), and explains that he's introduced them to the modern century, and that they too are destined to be part of Wyld Stallyns. As the four begin to play an amateurish cacophony of music, Rufus breaks the fourth wall and assures us, "They do get better."
