Supersaurus' Super Impact card was found in a Card Capsule at a golf course in Atlanta, Georgia, by Dewey in Tee'd Off. Eventually, the Alpha Gang tricked the card away from him, but forgot their Alpha Scanner. When they got it back, they used Super Impact for Altirhinus to summon Supersaurus against Chomp; it threw Altirhinus to hit Chomp, but the second attack accidentally hit and defeated Spiny because Chomp dodged it. Zoe then summoned Paris, who used Big Foot Assault to summon Seismosaurus to match Supersaurus. They fought against each other and were both equally strong. Supersaurus knocked over and slammed Seismosaurus, but Chomp used Lightning Strike to knock it over as well. Supersaurus launched Altirhinus again, but Seismosaurus hit him with its tail, sending him flying into the Alpha Gang's vehicle. Out of energy, Altirhinus returned to its card, making Supersaurus return along with it. Dewey got the Super Impact and Altirhinus cards and gave them to the D-Team.
A Supersaurus is seen in Carnival of Chaos under the Alpha Gang's control standing as the decoration for a roller coaster ride, the track running along its neck and tail. However, because it hadn't eaten for so many days, its control device malfunctioned and it went berserk. It returned to its card when the device was removed by either pet-sized Chomp, Ace, or Paris; the card was retrieved by an Alpha Droid and was never seen again. Its Move was likely linked to another Grass Dinosaur in the park, though this is never addressed.
