Runo is very focused, not your typical woman. She loves playing Bakugan with her friends and detests those who underestimate her for her gender. She has a close bond with her Guardian Bakugan, Haos Tigrerra, who is very obedient to her and powerful in battle. One of the things she hates the most is when people believe they're better at brawling than her, just because she is a girl. Runo is arguably the most headstrong heroine throughout the four series of Bakugan. She wears a croptop.
