His Character Unlock Missions appear once the player reaches Stage 9 in Duel World (DM); the Character Unlock Mission requires the player to Normal or Special Summon 5 FIRE monsters. Unlocking Soulburner also unlocks Duel World (VRAINS) as a result.
Just like Playmaker, Soulburner is another victim of the Lost Incident. After years of trauma, Soulburner decides to face his fears when he sees Playmaker fight against the Knights of Hanoi. He also forms a special friendship with Flame - the Fire Ignis. Known as Theodore Hamilton in the real world, he transfers to Den City High School to battle alongside Yusaku. As a Fire Duelist, he uses Salamangreats - which are Fire monsters from the Cyberse.
Before Soulburner Link Summons a "Salamangreat" Link Monster using a monster with the same name as Link Material, he announces "I blaze the circuit that scorches the path to the future! Reincarnation Link Summon!" if that monster does not have specific dialogue. Then, the Reincarnation Link Summon animation plays instead of his normal Link Summon animation.
