Deals damage. Has a 10% chance to burn the target. Has a critical hit rate one stage higher than normal. Assuming there are no other critical hit modifiers in play, this move has a 1/8 chance to get a critical hit instead of a 1/16 chance.
Blaze Kick is not exactly a bad move competitively, and yet is quite rarely seen. This is largely due to its poor distribution and imperfect accuracy. All of the fully evolved Pokemon that learn this move, Infernape, Blaziken, Lucario and Hitmonlee, can use it to reasonable effect, but mostly have better things to do. Blaziken and Infernape usually prefer to use the more powerful Flare Blitz, or attack on the special side with Fire Blast, and Lucario and Hitmonlee can find better coverage options, as they lack STAB on the move.
Fire Punch is a less powerful but more accurate move.
Flare Blitz is a much more powerful and more accurate move that causes recoil damage to the user.
