Card Trivia:Double Resonator
- This monster's name is a pun on its design: it is a "double-headed" monster with the English letter "W" (commonly pronounced "double-u") on its sash.
- This monster's name is also a pun on its effect to treat another monster as a Tuner monster, which will allow the player to Synchro Summon a Synchro Monster that can only be Summoned using two Tuner monsters as material (which is also known as "Double" Tuning in the anime).
