*** In his duel with Kaiba, Pegasus uses his Millennium Eye to predict Kaiba's moves and pulls this off twice. In one turn he uses a trap card called Prophecy to "guess" the attack power of a monster in Kaiba's hand, allowing him to take Kaiba's Blue-Eyes White Dragon. Pegasus then uses his Toon World card to summon Kaiba's Blue-Eyes as Blue-Eyes Toon Dragon. Later, he uses a Spell Card called Doppelgänger (Mimicat) to copy Kaiba's Crush Card Virus, destroying his whole Deck and winning him the Duel.

*** Joey's Graverobber Trap Card allows him to steal a card from his opponent's graveyard and use it as if it were his own, and he uses it a lot. The first time was against Bandit Keith in their duel by taking Keith's Time Machine card and using it to revive his Red-Eyes Black Metal Dragon. This also crosses over with BeatThemAtTheirOwnGame as Keith used his Pillager spell card to take and use Joey's Sword and Shield card in the same turn.
*** He later used it against Weevil Underwood in Battle City. Weevil used Eradicating Aerosol, an Insect-destroying Spell Card, to destroy his own Pinch Hopper, whose effect let him play his best card, Insect Queen. Joey later used Graverobber to copy Eradicating Aerosol and destroy Insect Queen.
*** In his second duel with Kaiba, Joey uses Graverobber to summon Kaiba's Blue-Eyes White Dragon to his side of the field. This only pushes Kaiba's BerserkButton and he still beats Joey.

From using Oba the archer's arrows to fire a shot into his groin, impaling Jan's testicles with Jan's trident, stabbing Dimitrios the knife-wielder's crotch using one of his own knives, smashing Anton the brute's nethers with Anton's hammer, pulling a CatchAndReturn on Aleksi's circular saws embedding each of his saws into Aleksi's nuts, and shoving Marco the axe-wielder's own ax down there.
