Lt. Surge is the 3rd Gym leader in the original Pokemon game(s) in Vermilion City. His specialty is electric pokemon, and defeating him will earn yourself the Thunder Badge.
Except you have to look through trash cans to find a switch that will lead you to the path in his gym. Seriously, Lt. Surge has all the time in the world to come up with something so bizarre and unnecessary.
I remember mostly fighting his favorite pokemon Raichu, who was the final evolution of the series staple Pikachu.
And once you got Pokemon Yellow (where Pikachu was the only starter pokemon), it was kinda like re-living the anime battle which was pretty epic.
