Robotic Fish Gone Wild!, known as Challenge of the Rampaging Fish! (暴走魚の挑戦 Bōsō sakana no chōsen!) in Japan, is the 5th episode of the MegaMan NT Warrior anime. It features the debut of SharkMan.


Lan and his friends brush up on their Net Battling skills before they are found by Maysa, who forces them spend time playing outside. Meanwhile, the World Three plots their revenge against Lan and MegaMan and hijack an aquarium full of robotic fish to do so. MegaMan is overpowered by a Jelly virus, but receives help from the mysterious SharkMan.


The episode starts off with Lan and his friends Netbattling in Yai's treehouse. MegaMan defeats GutsMan with a Mini Boomer for the 23rd time in a row by throwing the Mini Boomer at his nuts when someone breaks into Yai's property. This person turns out to be Maysa who gets a pan slammed onto his head for his efforts. He forces them all to go jogging, but when he finds out that they are using scooters and rollerblades, he forces them to do excruciating exercise before a fierce game of baseball which hilariously ends terribly since Lan and his friends fail to catch a single base-ball and Dex gets shot in the balls and understands how GutsMan feels.

Meanwhile Mr. Wily berates Count Zap Maddy and Mr. Match for their failures. They bicker, but formulate a plan to attack the robotic aquarium. Jelly viruses are unleashed on the aquarium's fish robots causing them to leave their cages and wreak havoc on the city.

Maysa is testing Lan and his friends on fish facts when they are besieged by the robotic fish. Maysa defeats an attacking fish with his knife while Yai and Lan sends in Glide and MegaMan to investigate. They are harassed by SharkMan who knocks MegaMan in to the water. World Three spots MegaMan on their monitors and order the Jelly to attack him. Glide asks Lan to help MegaMan, but the NetOps are being chased by robot fish.

Maysa helps them temporarily evade a robot shark, by telling them not to move, but his loud bragging brings them around again. MegaMan manages to get out of the water, but all the viruses merge to form a huge Jelly. Maysa acts as a distraction to lure the robot shark away while Lan and his friends make their way to the aquarium. Lan and co. are blocked by a giant squid on his way to the aquarium, but he manages to evade it and make it to the control room. He uses Sword to cut up the Jelly, but it regenerates and unleashes a tidal wave. With no useful Battle Chips, all feels lost but a fish bone arrow with and ElecSwrd Battle Chip is anonymously shot into the room. Lan uses it, but MegaMan has difficulty hitting it until SharkMan attacks the Jelly giving MegaMan the chance to delete it. SharkMan reveals himself as an ally before leaving. Megaman and Glide both comment that they thought SharkMan was just a Legend. Lan and co. wonder about Maysa as Maysa looks out at the sunset.
