Calm down Chibi, we don't know exactly what solo Kohaku loses or gains at this point. Stop saying stupid things Ultima, solo Kohaku is great in MBAC.
k i went and tested some things out
Solo Kohaku has Molotovs air and ground, which of course Tag Team Kohaku loses these.
Solo Kohaku has 6C, where as Tag Team Kohaku doesn't.
They both have 4B / BE4B
Solo Kohaku has the command grab, yada yada.
That's about all I could tell really.
Oh and if anyone was wondering how to do the Molotovs back and forth, it's really just 214B. Hold B and that's it.
