History Comicbook / TheBlackKnight

** After defeating Lusène the first time, Scrooge has the Black Knight armor locked away in a giant block of impervium that can only be reached with the Omnisolve umbrella. Unfortunately, Lusène uses a BatmanGambit to get Scrooge to reveal the wherebouts of the armor so he can steal it again.

* CameraShy: Arpin Lusène refuses to be photographed, and when reporters try to take photos of him, he demonstrates his ImpossibleTheft skills by stealing their film rolls and the filament from one reporter's camera.

* SealedEvilInACan: Scrooge still has the Omnisolve in the diamond jar that Gyro made for him, then put it in a safe with diamond coating on the inside to ensure it will never get out and possibly destroy the planet. Unfortunately, Lusène mistakes it for a valuable prize and steals it.

* ExplainExplainOhCrap: Lusène effortlessly breaks into the Money Bin during his first caper. Besides a bag of diamond dust worth a whoppin' 100 dollars and a suit of armor, Scrooge is unsure what exactly Lusène stole that night, since nothing in his vault nor his trophy room appears to be missing. He doesn't consider the safe containing the Omnisolve, since Scrooge doesn't believe it has any value to the Black Knight (in fact, as the name suggests, it is literally the most dangerous substance on Earth) until Louie points out that a combination safe would be irresistible to a master thief like Lusène. When Scrooge realizes this, he rushes to open it. All he finds is Lusène's CallingCard, confirming the Ducks' worries.

Duckburg is visited by Arpin Lusène, a distinguished French gentleman who is unofficially known to be ''Le Chevalier Noir'', a notorious master thief. As his final theft before retirement, he vows to steal Scrooge [=McDuck=]'s fortune as the crowning achievement of his career. After a successful heist in the Money Bin that apparently yields little of value, Lusène accidentally comes in the possession of the dangerous Universal Solvent, a substance invented by Gyro Gearloose capable of destroying anything it touches (except diamond). Together with a stolen suit of armor and a bag of diamond dust, Lusène uses the Solvent to become an unstoppable BlackKnight.

* CallBack: The Universal Solvent was actually the focus of an earlier Don Rosa story of the same name.

* PullingTheRugOut: The Ducks lay out a red carpet in front of Scrooge's money vault to celebrate an occasion. This becomes a ChekhovsGun later on when the [[BlackKnight indestructible Black Knight]] Arpin Lusene breaks into Scrooge's money bin with the intent to dissolve his entire fortune. While looking down Scrooge gets the idea to pull the carpet out from under Lusene and send him falling straight the floor inside his dissolving suit, a pile of diamonds (the one mineral unaffected by it) breaking his fall.
