Card Trivia:U.A. Blockbacker
- This monster is based on the linebacker in North American football, who plays an important role in their team's defensive strategy.
- "Blockbacker" in this card's name is a portmanteau of the terms "linebacker" and "blocking", the latter term referring to legal movements a player can make to block another player's path with their body.
- This monster's effect reflects the blitz tactic in North American football, in which linebackers can be called upon to tackle the quarterback (reflecting the change in battle position and effect negation).
