Her jumping roundhouse doesn’t actually cross up it looks like it should, but it won’t actually cross up in any situation that matters.
Morrigan’s trijump low jab is hella fast if you just do it off a normal jump. From there, it’s easy to do low shorts into Tron, but it’s a little harder to follow through. However, if you airdash over their head while calling Tron, you can s.fierce them back into that shit.
Morrigan/Sent/Tron 100% combo: crossup and call tron, s.fierce xx fierce fb xx DI, DHC into HSF when they fly up, then launch them and do whatever. The HSF will whiff entirely, so everything is taking off as if you just did it. Even if you just do short-short-RP, they’re pretty much dead.
Other cute combos:
when they tag in, do the magic series while calling Tron. It looks sick/retarded, and does 60 points of damage to boot, and if you feel like it you can tack on a DP super at the end for shits n giggles.
Also keep jab DP in mind. Hella good if you get in trouble! Morrigan can play a ground game all day, and if they try to jump, SHOOOORYUKEN.
