Let's come up with some interesting signature moves for your favorite pokemon. I'll start.

Beedrill. Final Sting. Bug type. Physical. 140 base power. 5PP. 100% acc. This move causes the user to faint and deal damage to the opponent ignoring some of its defense based on how much hp the user had left. 100% hp completely ignores its defense stat, 99 - 75% hp ignores 75% of its defense, 74 - 50% hp ignores 50% of its defense, and 49 - 1% hp ignores 25% of its defense.

Greninja. Shadow Double. Dark type. Status. 15PP. Gives the user a 50% chance to avoid attacks for 3 turns. Once the opponent misses due to this effect, the effect ends immediately and the opponent receives any negative effects it would have normally received if the attack hit(life orb recoil, stat drops from close combat, etc)
