Final Gambit (いのちがけ Extreme Risk) is a Fighting-type move introduced in Generation V. The user deals a life risking attack and faints, and the opponent receives damage equal to the user's lost HP. If this move misses, the user doesn't faint.

Despite being a Fighting-type move, only three fighting types can learn it.
If Victini were to use Final Gambit at level 100 with 31 IVs and maximum investment in HP, then it could deal 404 damage: the highest possible damage that a Pokémon that can learn this move by leveling-up could do. The Fighting-type that could attack with the highest amount of damage with a nature that raises HP and have 31 IVs in HP would be Lucario at 344 HP (Lucario could learn Final Gambit as a Riolu if it evolves after level 55).
