DustMan helps manage the trash in the Net whilst working with Mr. Press in promoting recycling. They enter the Navi Mascot competition in order to promote recycling. DustMan and Mr. Press meet Lan Hikari and MegaMan.EXE during their quest to find the Moonstone. Several HeelNavis attack them and try to unleash the Cybeast. But, DustMan shows up and defeats them using his Dust Break ability. Mr. Press and DustMan introduce themselves to Lan and MegaMan who then leave to continue searching for the Moonstone. Mr. Press and DustMan lose the Mascot competition however and are later found giving lessons on recycling in Seaside Town. After Lan takes a few lessons from Mr. Press, MegaMan then spars with DustMan, eventually obtaining his Cross and DustMan as a Link Navi. DustMan can be rebattled afterwards for his Mega Chip.
DustMan and Mr. Press are seen in Beyondard with GroundMan.EXE and Moliarty. The team specializes in drilling through rock, either for construction of tunnels or excavation. They are enlisted by Beyondard's Ms. Millions in order to help her finish construction of a tunnel that will link two towns that are separated by a mountain. DustMan and GroundMan are materialized and work together to try and break a rock blocking the way. GroundMan drills into the rock while DustMan pushes him forward, but they fail to break the rock and have to return to their PETs. The rock is broken later with the help of the village on the other side. In Beast+, an image of him appears in a video game in the third episode.
