Rodyle

Rodyle (ロディル, Rodiru) is an antagonist in Tales of Symphonia and one of the Five Desian Grand Cardinals. He oversees the Remote Island Human Ranch.

The Angelus Project
At some point several years before the game, Presea's sister Alicia left to serve the Bryants, and her father, Sieg, became very ill and unable to continue working as a lumberjack. She had to continue working to feed her and her father, so she forged a deal with Rodyle, that she would take part in his expeiriments in exchange for enough power to weild her father's axe and continue working in his place. Rodyle performed these experiments without Cruxis knowing, and planned to use the power of the Angelus Project to overthrow Pronyma and became the leader of the Five Grand Cardinals.

The Mana Cannon and Ranch Infiltration
After learning that Rodyle is planning to use a Mana Cannon to make himself the ruler of the two worlds, Lloyd and the party, as well as Botta and a few of the Renegades, infiltrate the Remote Human Ranch. Along the way, the party frees the prisoners that are imprisoned inside of the ranch. When Rodyle is found by the party, he traps the prisoners that they had helped to escape in a room, and starts to flow water into it, hoping to drown them. Just before he fights the party, he equips what-he-believes-to-be-a Cruxis Crystal to himself, transforming his body into a monster. After he is defeated, he realizes that Pronyma, the person who gave him the "Cruxis Crystal", tricked him, and that is body is falling apart. Before dying, Rodyle activates the self-destruct sequence of the ranch, and dies at the controls.

Boss Battle
As a Desian Grand Cardinal, Rodyle is a formidable opponent. Rodyle fights alone and is fought as an advanced mutated Exbelua-type creature rather than in his half-elf form. The mutation grants him massive offense and defense at the cost of speed and mobility. He is armed with a sickle on his massive forearm, slicing with it or simply smashing it onto the ground for heavy damage. Rodyle makes use of powerful Earth magic, casting Grave and Gravity Well effectively. Rodyle has an exclusive technique available only to him known as Insanity Force, though the move's name is very similar to Marble's Insane Cell. The move sees him harnessing white energy on his chest plate, then releasing it in a violent explosion. Any target caught in the blast is dealt massive damage and is blown away.
