Runo Misaki, a human Haos-attribute brawler from the Bakugan franchise, appears across multiple seasons. Initially headstrong and competitive, she partners primarily with Tigrerra—later evolving into Blade Tigrerra—and helps operate her family's restaurant. She harbors unspoken romantic feelings for Dan Kuso, balancing determination and combativeness against gender-based underestimation with loyalty toward friends. Early losses of Bakugan to the Doom Dimension tested but solidified her commitment to brawling. In *Bakugan Battle Brawlers*, she ranked sixth globally. Confronting the Haos Legendary Soldier Lars Lion in the Doom Dimension forced her to overcome stubbornness, triggering Tigrerra’s evolution. She battled Naga and later shared a date with Dan post-season. Her role diminished in *New Vestroia*. Frustrated by Dan’s absence, she impulsively traveled to New Vestroia through an unstable portal, losing her physical form and inadvertently hindering the Resistance. Stranded on Earth without a Gauntlet, she reclaimed Blade Tigrerra but operated supportively, protesting exclusion from King Zenoheld’s final battle. She appeared only in flashbacks and photographs during *Gundalian Invaders*. Runo returned in *Mechtanium Surge*’s second arc after being seen solely in photographs earlier. Applying Vestal technology knowledge gained during the time gap, she assisted Mira Fermin in deploying Battle Suits against Wiseman and rogue Mechtogan. She briefly partnered with Haos Bakugan Aerogan, fighting alongside Dan in "Jump to Victory" before Aerogan’s return to New Vestroia. Ordered to remain at headquarters during Wiseman’s hideout infiltration, she later perished with Mira and Julie in "Doom Dimension Throwdown" when Mechtavius Destroyer obliterated Bakugan City. Dan, Shun, and Marucho reversed this via the Current of Time. In the altered timeline ("Beginning of the End"), she coordinated Battle Suit deployment from headquarters during the final conflict and attended Dan’s celebration after Mag Mel and Razenoid’s defeat.
