Card Trivia:Gadget Soldier
- This card has a counterpart: "Mighty Guard".
- This is the first "Gadget" monster to be released, although this was before the archetype was officially created with "Boot-Up Soldier - Dread Dynamo".
- In the original Yu-Gi-Oh! manga, this card was a Level 4 monster. In Yu-Gi-Oh! Duel Monsters 4: Battle of Great Duelist, just like with many Monster Cards' Levels, this card's Level was changed to Level 6, which would later be carried over to when it was released in the OCG/TCG.
