GroundMan and Moliarty enter the Navi Mascot Competition, but lose. They then give lessons at Central Town's school on drilling through rocks. Lan Hikari takes this lesson and has to operate GroundMan to drill through rocks in the Cyberworld. After completing the task, he and MegaMan.EXE Netbattle GroundMan and Moliarty. After winning, GroundMan becomes a Link Navi and gives MegaMan his Cross.
In the Beast anime, GroundMan and Moliarty are seen in Beyondard working with DustMan and Mr. Press. The team specializes in drilling through rock, either to construct tunnels or for excavation. They are enlisted by Beyondard Ms. Millions to help her finish a tunnel that can link two towns that are separated by a mountain. GroundMan and DustMan are materialized in front of the rock and they try to break it. They work in a combo in which GroundMan drills and DustMan pushes him. However, they are unable to break the rock and are forced to return to their PET's. The rock is later broken by Chaud and the villagers on the other side. GroundMan appears later in Beast+, in a video game in third episode and to give Ground Cross to MegaMan.
