Initially, she is hesitant to join the team until she is convinced that Gear's evil would eventually put the animals in danger. When Gear manage to gather a bit of Anti-Bio Particles to weaponize, Mika dies by Pysgorn's hand sacrificing herself to empty Bio Killer Gun's ammo so her allies can fight without being poisoned by the Anti-Bio Particles. The others mourn her as Bio Robo activates her Bio-Brain Computer to present her memories to give the Bioman hope. Her Bio Brain Computer allows her to present photographic projections in her Super Electron Holography (超電子ホログラフィ, Chōdenshi Horogurafi?) ability. Her weapon was the Thunder Sword (サンダーソード, Sandā Sōdo?). Her special attack is Strobe Flash.
