I'll post more info when i manage to beat him. I don't know what the unlock conditions for it are either. The battle appeared just as I beat the last area boss for the zone, clearing it completely, so odds are good that that may be one of the requirements. I also already have Poseidon, but I don't know if that is a requirement for it to occur.

I'm curious to see if it is a way to get more of an advanced summoning you have, but i won't know until i beat him.
