Wren is an android who cares over the Kuran sattelite system, monitoring the welfare of the Algol System. He joins the Protectors in order to help them solve the problems that plague Algol. Wren, along with Seed, taught Rika knowledge about Algol from afar, and he is even older than Demi, retaining the same calm and logical prowess his fellow android has.

In-battle, he is... very, very resilient. He has absurd durability, and he has very efficient repair systems and mechanisms to raise his magical defenses. His tankiness surpasses all the game's other duellers, and due to his Algol equipment, he enjoys a heavy resistance to Lightining along with his natural resistance to Fire and Ice. His damage is somewhat suspect, but his massive amounts of healing, status resistance, and general ability to take punishment nonetheless proved him to be too powerful for heavy. Hopefully, he can keep on tankin' in a higher division.
