Question: Rebel Black Bear is the mascot of the collegiate athletic teams formerly known as what?

Context paragraphs:
Hey Reb!: Hey Reb!  is the mascot for the UNLV Rebels, the athletic teams of the University of Nevada, Las Vegas in Paradise, Nevada, USA.  He performs live at all UNLV athletic events.  The campus community is divided over the contention that the mascot, looking like a confederate soldier, appears to be a symbol of racism.  The mascot was first created in 1983 to depict the embodiment of an independent, rebel spirit at UNLV athletic events.  As race discrimination issues dominated national events, community members voiced concerns that Beauregard glorified the Confederacy and had little to do with the community's history.  In the early 1970s, students voted to banish Beauregard but retained the Rebels name (rejecting alternatives such as Big Horn Rams, Nuggets, A-Bombs, and Sand Burners).  Replacing Beau was a musket-toting Minuteman, but that Revolutionary War figure didn't resonate in the West either.  So UNLV essentially went without an official mascot.

Petey (mascot): Petey is the mascot for the Canisius Golden Griffins, the athletic teams of Canisius College in Buffalo, New York, USA.  Petey is an anthropomorphic golden griffin who performs live at all Canisius athletic events.  Canisius adopted the nickname "Golden Griffins" for their school athletic teams in 1932, in honor of Great Lakes explorer La Salle's ship, "Le Griffon".  Canisius first used an unnamed costumed griffin as a sideline mascot in 1967.  In preparation for the 2002–2003 athletic season, the griffin mascot was completely re-designed and given a new costume and name.  The name "Petey" was chosen as a reference to St. Peter Canisius, who Canisius College is named for.

Arizona State Sun Devils: The Arizona State Sun Devils are the athletic teams that represent Arizona State University.

ASU's chief rival is the University of Arizona Wildcats.

Before the transfer, SFU did not compete in Canadian football, instead playing American football.

The only exception is the rifle team, which participates in the Great America Rifle Conference because the SEC does not sponsor that sport.  The school's colors are red (PMS 186) and navy blue (PMS 2767), purposely chosen to mirror the school colors of Harvard and Yale, respectively.  With a long history in intercollegiate athletics (Ole Miss began football in 1890), the university competes in 18 men's and women's sports.
