in mh1 Rathian was in the same rank as Rathalos, and thus, with the sudden poison tail slap (x3), triple charge and rapid fireball x3 always have been the strongest counterpart of the couple (as in power)... in mh2 and mh3 they had to put her in a lesser rank (like same as Gobul, "1 step lower than flagships") just to cut her max. HP and make her weaker than rathalos, just to avoid Rathalos shaming (and it kinda continues with the Seregios intros)

also, nope, it was in both (source BannedLagiacrus), the "hypnosis" are the pheromones. no mind control, it's the same as the Insect Glaive
