Even then, I believe the main team had to make their own models for those 2. They didn't use the Frontier ones. If you notice, Unite's Lavasioth and Hypnocatrice are physically different in Frontier and in Unite: compare Lava's head in the two versions and you'll see it.

Of course, their attacks are also different: MHFO's Hypno deals damage with its sleep breath and doesn't perform the kick attack, and Lavasioth can't do the turning landslide (at least no in the same fashion)
