"Rider" (ライダー Raidā) is a series of biker-themed monsters used by Kozaky in the Yu-Gi-Oh! GX anime. With the exception of "Dokurorider", all monsters of this series are Level 4 WIND Effect Monsters with 1500 DEF.
A Deck utilizing this series focuses on quickly amassing large amounts of Spell and Trap Cards in the Graveyard so that they can be banished by "Diskblade Rider" and "Chaosrider Gustaph", respectively, to increase their ATK, until the opponent's next End Phase.
They are used by Kozaky in the Yu-Gi-Oh! GX anime.
