The next 2-on-2 match is Netto and Commander Beef against Bombman and Stoneman! Masa gives Netto a lot of encouragement before the match. After it starts, Rockman and Beef's Sharkman get a good lead against Bombman and Stoneman... but being World Three members, the two have a plan up their sleeves. They transport Sharkman and Rockman through a worm-hole and take them to a mysterious network, away from the aid of battle chips! It's the lighthouse near the stadium, so Beef and Netto rush off to save their navis. But the lighthouse is being guarded by the robots from last episode!
