The Last Kraken is a boss found in Aglis in disc 4. It has been summoned by Savan to be a guardian of the signet of Soa and the backup Signet Moot that Savan created. Should Savan's plan succeed, the Signet would be doubly safe from anyone who dares try to break it and free the body of the Virage Embryo and bring it to earth.
After the Last Kraken scuttles its giant form forward, the voice of Zieg is heard. It seems the Last Kraken is under Zieg's control. Luckily, the Last Kraken is the only enemy to kill because Zieg doesn't want to get his hands dirty. After the party defeats the Last Kraken, Zieg breaks the first signet and then flies away.
Cleone Spawn: seems like he shoots out two fairies called "Cleones" that are both monsters and attacks; if you don't swat at them they may cast a Light spell, "Light Eraser" at a party member, or may fly at a party member and explode ("Genocide"). If there are no fairies on the field, he will spawn two more. Even if he dies, the battle will continue until the fairies are dead.
Tentacle Slap: he attacks with his tentacles
Conduction Magic: his back shows lightning, and he casts a single spell of either Water or Thunder; this can be a real pain because one of his spells causes a lot of damage. There is also multiple character spells that he casts on party members.
Water Current Gun: He lifts up his upper-shell and a water cannon shows and fires a large amount of water at one party member dealing large amount of damage
Just like with second fight with Lenus on Poison Island. Going in Dragoon Form may cause a Game Crash at the end of battle.
