The Second Generation of Bakugan, also known as Bakugan Reboot Series, or Reboot (Unofficial name), refers to an era of the franchise that started in 2018, with the tease of the Bakugan Battle Planet website. The Reboot features some characters and Bakugan from the Legacy series, but only in name; no direct references to previously existing characters has been made.
In 2023, the franchise was rebooted again, leading to the Generation 3 era.
Note: The majority of these characters and Bakugan are returning in name only, and either bear no connection to their Legacy counterparts, or only serve similar roles in the show.
