It's the fact he has good teleports as well as that ball super and the pillars. It makes you feel like you are fighting a uphill battle the whole time where morrigan or vergil leave you thinking oh I can get one good hit in here and winNah, Morrigan lets you feel like you are in control and Zero doesn't suffocate you... he takes your stick and smashes it on the floor so he can proceed with the one player game.
Not even Vergil feels as bad as Dormington does. Maybe it just feels worse because I've been put through the grinder by Karst.
