** '''[[https://yugioh.fandom.com/wiki/Relinquished Relinquished]]''' is built around this trope. Powerless on its own, it was the first monster capable of absorbing other monsters, and it copied that monster's ATK and DEF. If the opponent attacks it, they lose as many Life Points as the controller does and the equipped monster is destroyed instead of Relinquished. Its superior form [[https://yugioh.fandom.com/wiki/Thousand-Eyes_Restrict Thousand-Eyes Restrict]] trades the damage duplication effect for ''banning all other monsters from attacking'', and its perfected form released years later, [[https://yugioh.fandom.com/wiki/Millennium-Eyes_Restrict Millennium-Eyes Restrict]], can equip multiple monsters at a time, taking on their ATK and DEF and barring all monsters with that name from attacking or using their effects.

** ''VideoGame/DevilMayCry1'': In Trish's first scene, she impales Dante with Force Edge, the sword his father gave to him, before trying to finish him off by throwing her motorcycle at him. This being Dante, he shrugs it off and blasts the bike with his guns.
