The Super Rod (Japanese: すごいつりざお Amazing Fishing Rod) is an upgrade to the Good Rod that can be used to catch stronger Pokémon by fishing. A stronger Pokémon that can be found by fishing can be reeled in with the use of the Super Rod, and in some generations, Pokémon that would not be found in the open.
How to Obtain
Generations I and II
The Super Rod can be obtained by traveling to Route 12 in Kanto and entering the lone house on the Silence Bridge (below the Route 11 entrance). The tenant inside the house is one of the Fishing Gurus that inhabit the Kanto region, and will give the player the Super Rod.
In Pokémon FireRed and LeafGreen (which are updated remakes of Generation I), the Super Rod can be obtained at the same location as the first generation.
