Brooklyn Nets
After the Nets' move to Brooklyn, the team introduced a new superhero mascot named BrooklyKnight (a pun on the demonym "Brooklynite") on November 3, 2012. In his first appearance, he was lowered from the ceiling of the Barclays Center amid sparks and fanfare and introduced by Nets PA announcer David Diamante: "Here to defend Brooklyn, he's the BrooklyKnight." The mascot was co-created by Marvel Entertainment, a sister company to NBA broadcasters ABC and ESPN. The character also starred in 32-page comic book published by Marvel titled "BrooklyKnight #1", written by Jason Aaron with art by Mike Deodato. After the Nets' second season in Brooklyn, the BrooklyKnight mascot was retired.
Knicks–Nets rivalry
The rivalry began in 1976 when the Nets joined the NBA as part of the ABA–NBA merger. At the time, the team was known as the New York Nets and played at Nassau Veterans Memorial Coliseum in suburban Long Island. The team became the New Jersey Nets the following season when they relocated to suburban New Jersey, playing temporarily in Piscataway before moving to Brendan Byrne Arena in East Rutherford in 1981, their home until 2010. The Nets played their final two seasons in New Jersey at Prudential Center in downtown Newark. The rivalry became an intra-city series when the Nets relocated to Brooklyn in 2012.
