The form change is just athing that some video games use for boss fights... I see it as pointless and unnecessary, but some view it as cool. Also, Korri isn't the type to do something like that anyway - by the time you face him, he's already more or less aware of most of your capabilities and he'lll choose how much power to use accordingly, immediately.
