All of the minor Chaos Bakugan (minus the six used by Teams Anubias and Sellon) are based off of three of the Guardian Bakugan from New Vestroia: Knight Percival, Ingram and Neo Dragonoid.
Anubias and Sellon's role in resurrecting Mag Mel is similar to Crusadermon's and Dynasmon's role in resurrecting Lucemon in the anime Digimon Frontier as they're both summoned by their masters, both gathered data to aid in their master's resurrection e.g. Anubias and Sellon gathered battling energy from Bakugan Interspace and Crusadermon and Dynasmon scanned locations in the Digital World, and they're both drained by their masters in order to become powerful.
