It’s the SEQUEL of Space Jam. The Monstars were from the first film. The new five ENEMY players are the GOON SQUAD from Space Jam 2: A New Legacy. Did you not watch the Sequel?
Crane MonStars & the GoonSquad are different because the MonsStars are from the original space jam movie from 1996 while the space jam today in 2021 is the GoonSquad
