Onihime and Yasha

Yasha & Onihime (鬼姫&夜叉, known as Mona and Lisa in PAL and US versions of Streets of Rage 3) were twin bosses in Streets of Rage and later they made a new appearance in Streets of Rage 3. These twins of Japanese descent fight with outstanding teamwork.

In Sreets of Rage 1, Yasha and Onihime appear as pallete swaps of the sprites used for Blaze. One often approaches in the air with a jump kick, while the other approaches on the ground for a throw at the same time. They are arguably he toughest bosses in the game, especially when played solo, because of their coordinated team attacks.

In Streets of Rage 3, they look a lot different from their Streets of Rage 1 counterparts. Yasha/Lisa is the aggressive twin who will always try to jump and kick the player(s). Onihime/Mona is the passive twin who does not try to kick the player(s), unless she is doing the Twin Spin Kick team attack or if Yasha/Lisa is defeated. Onihime/Mona grabs for a throw or suplex, fires grounded projectiles across the room (which is another team attack), throws Yasha/Lisa up high in another team move for Yasha/Lisa to do her Homing Kick. When Yasha/Lisa is defeated, Onihime/Mona gains Yasha's/Lisa's moves.

In When the Cold Breeze Blows Away,they are mentioned in various picture of them but therefore, it would have the Twin Fulauser - Medici Mafia counterpart of Yasha & Onihime.
