His enemy is Blue-Eyes White Dragon.
In Yu-Gi-Oh! The Movie, he appeared as an anti-hero when he holds the rocks along with Toon Dark Magician Girl but both are presumably destroyed in the process during the battle against Anubis.
He was also a friend of Toon Dark Magician Girl, Toon Dark Magician, Toon Gemini Elf and all of Toon Monsters including Red-Eyes Toon Dragon and Toon Mermaid, as well as Manga Ryu-Ran.
Blue-Eyes Toon Dragon is portrayed as a child version of Blue-Eyes White Dragon similiar to Toon Link from The Legend of Zelda franchise.
This Toon Monster is summoned by Toon World when the player pays 1000 Life Points to activate this card.
