Shun Kazami: He is a strong, silent, cool type 12-year-old. He was the 1st ranked Bakugan player until Masquarade came then he moved down to 6th place then to 3rd place. He created the rules and regulations of Bakugan with Dan and is a master of the game, and also is Dan's childhood friend. Shun is a loner, a boy of very few words, yet is willing to help his friends at every turn. He seems to have a crush on Alice. He approaches the game like a ninja, being very calculating. He lives with his grandfather (who used to be a famous ninja warrior) who once expected Shun to follow in his footsteps instead of playing Bakugan. His Guardian Bakugan is the Ventus-attribute Storm Skyress whom Shun received from his comatose mother.
Alice Gehabich: She is a 14-year-old girl from Moscow who didn't play Bakugan until her identity of Masquerade had disappeared from her body. Upon his departure, Masquerade left her the Darkus-attribute Hydranoid. Michael is her grandfather, but after learning that her grandfather became Hal-G and works with Naga, she constantly worried about him. Alice usually just gives advice to the brawlers, instead of battling. In the anime it appears as though she has a crush on Shun. Alice and Marucho are the stratigest of the brawlers, but unlike Marucho, Alice gives her strategies to the brawelers. Alice has a special ability to see the G's of an Bakugan on the field. Her Guardian Bakugan is Darkus-attribute Ultimate Hydranoid which she inherited from Masquerade after he left her body.
