QuickMan.EXE

Quickman is a quick, agile, and loyal NetNavi. Operated by Daisuke Hayami, he helps Gospel succeed in their plans of world domination, until he was attacked and betrayed by one of Gospel's commanders named Cutman in Episode 35. Quickman's Quick Boomerang attack is ultra fast and is hard to avoid even for the best of navis.

After the events with Gospel collapse, it's revealed that Daisuke was only working for Gospel in order to protect the beauty of nature. Thus, Quickman and Rockman end up parting as friends, not enemies.
