|Season:||Kamen Rider Spade Warrior|
|Fake Kamen Rider Spade Warrior|
Trial E is a Shooting-Type Undead based on Diamond Warrior's data & DNA. Destroyed by Spade Warrior King Form's Royal Straight Flush. Another appeared later in the series, disguised as Ray wearing a red scarf, it copied the Spade Buckle & transformed into Kamen Rider Spade Warrior. He fought the real Spade Warrior to a standstill with the clueless Kent Newman & Andy Borg unable to tell the obvious difference until Dirk Trent came in & called out Spade Warrior's name, exposing Trial E as the impostor when it reacted faster than Ray. He was eventually defeated by Spade Warrior's Jack & King Form with the help of Club Warrior's Remote Tapir & Diamond Warrior's Gemini Zebra.
