TM91 Flash Cannon is located deep inside Twist Mountain on the bottom floor. The fastest way to reach the TM is by starting by at Icirrus City.
From the Icirrus City Pokémon Center, head south and enter Twist Mountain. Then you’ll need to make your way to the Mountain’s basement floor to find TM91.
But before you’re able to reach Twist Mountain, you’ll need to defeat Mistralton City’s Gym Leader Skyla.
Flash Cannon is a Steel-type move with 80 base Power. It also has a slight chance of lowering the Special Defense of its target by one stage.

TM91 Flash Cannon Details + Uses
|Flash Cannon Move Details|
Flash Cannon is one of the most powerful Steel-type moves that can be taught in BW.
Its 80 base Power may not seem like much, but there are only a few Steel-type attacks that can be considered stronger in Pokémon Black/White. Flash Cannon is also one of the only Steel-type moves that fall under the Special category.
Along with considerable damage and perfect accuracy, Flash Cannon also has a 10% chance of lowering the Special Defense of its target by one stage.
Magnezone and Lucario are both strong Steel-types that can benefit from learning the move, as their high Special Attack stats provide Flash Cannon with a considerable damage boost.
