Jago is on eof the hardest characters to learn in Ki1,but one of the best in Ki2. I'll start with ki1.
Jago has little going for him in ki1. He is fast,unpredictable,has a great overhead,and is hard to break. His downsides are that he has no range,E-Z to get creamed after a blocked attack, and he has to be in thier faces all the time. :-{
Despite this though,Jago is very good.
his best openers are -d+mk,2n1 to a mk windkick. -overhead to a mk windkick. -mp,mp,then anything!
