|Season:||Kamen Rider Spade Warrior|
|Plant Undead Rouze Card|
The Plant Undead is the first Undead Ray Agema encounters after BOARD was disbanded, first appearing at an observatory to strangle people. But due to the fact that Ada Chastain was there, Heart Warrior arrives after the monster eludes Spade Warrior & goes after the girl. After Heart Warrior leaves with Ada, the Plant Undead telepathically calls Heart Warrior out before ambushing Spade Warrior while awaiting for his opponent's arrival. Once Heart Warrior arrives, the Plant Undead is sealed by him.
