Enkidu's powers are broken as hell. Only a Pioneer can kill him, and he can deliver death to anyone else that "they deserve." Tiara technically wasn't a princess of Zahard, but only because she turned it down. Considering how much trouble she gave Yuri, Enkidu is an absolute MONSTER! He's a threat to everyone in that game, and working for the Rachel-Bellerir faction to boot...not good.
Hopefully, we've got a lore dump coming. If anyone has the means to revive Baam and Khun, it's Gustang. The sweetfish powers remind me of Gustang's flames a bit.
All of this seems like it's going too easily to plan for Gustang's group. Traumerei has been tooled throughout the arc. I hope his clapback is heavy.
