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.
History of the New York Islanders
On October 24, 2012, the Islanders made the announcement that the franchise will indeed be moving to the Barclays Center in Brooklyn for the 2015–16 NHL season, after signing a lease that would keep the team in the arena until 2040. The team retained its name, logo and colors as part of the move. As part of the deal, the management of the Barclays Center took over the team's business operations once the Islanders moved to the Barclays Center. The decision to move to Brooklyn didn't require the Rangers' approval. Under a longstanding provision of the agreement that allowed the Islanders to share the New York area with the Rangers, the Islanders are allowed to play their games anywhere on Long Island, including the two city boroughs on the island, Brooklyn and Queens.
