roffman
A roffman is a rare pokemon found only within the Glitch City bug in Pokemon Red. Trainer encountering a roffman should be careful as defeating a roffman immediately deletes all Pokemon in your current party. Capturing a roffman causes specific items in your inventory to duplicate. These items include TMs Rage, Self-destruct and Reflect. A glitch key item called stuN seeD is also created.
Woah you caught a roffman! How lucky!
