He's an obnoxious boss in pretty unfun way in that he's just a check on how many Phoenix Downs you bring into Zozo with you, and whether you have some means to constantly re-apply slow and sap. I'm not sure if he just has a gigantic meat wall of base hp, but I had Cyan churning out 1100-1200 damage Dispatches constantly and it still felt like the fight took somewhere over 5 minutes to complete. To be fair, I completely forgot that Empowerer sets Sap, so that one was on me.
It's also kind of annoying that he has two different ways to one-shot characters, and to the best of my knowledge there's no way to set Protect this early. Throwing spoons is moderately funny the first time he does it, but every time after it just heralds that you're about to burn another Phoenix Down. My team for Zozo was Celes, Locke, Edgar, and Cyan, so possibly there was some other method.
