Being based from Hayate, he was good but his effectiveness is stunted by his gimped moveset. Using him over Hayate is like using Kasumi @ over Kasumi, same style but less moves and more primitive.
i actually prefered kasumi alpha over DOAD kasumi, and i actually liked Shinden (aka reskinned doa 3 hayate) over DOAD hayate. as to wether he was good, he was, not amazing but not shit tier either; but his effectivness is ruined when a better version of him with more tools exists in the same game
