No Skills

No Skills is a special status condition that is commonly seen in the RPGs.

Paper Mario
In Paper Mario, No Skills is rather rare in the game. When Mario is hit by a move that causes No Skills, then he cannot use a certain skill for a number of turns. This includes using his jump, hammer, or even items. All three can occur at once which can be very troublesome as it leaves Mario without an option to attack forcing him to rely on his partners. Spy Guys, Fuzzipede, and Bowser himself are the only ones that can cause No Skills in the game. Mario will get his commands back over time.

Paper Mario: The Thousand-Year Door
In Paper Mario: The Thousand-Year Door, No Skills return still as a rather rare condition. The only difference now is that Mario's partners can be affected as well. No Skills is caused by Bowser again but now by the three dragons in the game: Hooktail, Gloomtail, and Bonetail.
