 * Mirror Knight's attack, Silver Cross, shares it's name with Mirrorman's signature attack. The draft name for this attack was Slicer H (スライサーH).
 * Mirror Knight's first appearance homages Mirrorman's transformation.
 * Like the hero Mirrorman whose father was a previous Mirror Man, while his mother was human; Mirror Knight's father was from the Mirror Planet, while his mother was from Planet Esmeralda, this was possible because the two worlds were close before the mirror world withdrew from stellar affairs in response to the Belial Invasion.
 * Tsuburaya Productions was originally going to name him Mirror Master, that name was used to name his counter part from The Spirits of TSUBURAYA PRODUCTIONS WORLD: Another Genesis, a novel serialized in Dengeki Hobby Magazine. In it his counterpart was a villain and the master of Tiga who later rebelled against him.
 * Mirror Knight's voice actor, Hikaru Midorikawa, is known for his role as Heero Yuy in Mobile Suit Gundam Wing. The word Yuy on Heero's name comes from a Japanese word "Ui" (有為), matching that of Mirror Knight's demeanour and outlook.
 * Interestingly, one of the Singles for that series is "White Reflection", by Minami Takayama.
