- In episode 43, this monster ambushes Seto Kaiba and activates "Dragon Capture Jar" to capture Kaiba's "Blue-Eyes White Dragon" before it traps Kaiba with a net and captures him.
- In episode 44, Another Armed Ninja appeared later and took out Yugi Muto's "Dark Hole" with a snipe before it captured what was at first Princess Adena (really Mokuba Kaiba in disguise) with a net. Joey Wheeler then summons "Axe Raider" and equips it with "Kunai with Chain". "Axe Raider" then destroys the "Armed Ninja", which causes the net to drop, but a "Whiptail Crow" then catches the net and takes it away.
- In episode 45, Kaiba and Mokuba tried to escape from the castle's prison, but an army of "Armed Ninjas" appeared and tried to capture Kaiba's second "Blue-Eyes White Dragon" (which was summoned earlier to destroy "Witty Phantom") with "Dragon Capture Jar". Kaiba anticipates this by summoning "Trap Master" whose effect destroys the jar and frees the "Blue-Eyes White Dragon" that was trapped in it earlier. Kaiba then used both his "Blue-Eyes White Dragons" to destroy the army of "Armed Ninjas".
