i think the reason behind that is because their fate has changed, they haven't changed at all. The only major changes they made on a unit's lore and animation once they've reach Omni is the 6 heroes since their lore changed completely (Vargas became a general, Selena choosing the free life, Eze leading an army instead of pridefully going off, Lance uses a SPEAR instead of a lance, Atro became a monk instead of venturing, Magress took of his armor. They've completely changed). Or because the devs are lazy to add new animations so they just copy and paste
