Palutena announces "Lightweight!", and the effect takes place almost immediately. Functioning similarly to Shulk's Jump and Speed Monado Arts, Palutena's jump, dashing and walking speed are doubled, greatly enhancing her mobility. The effect last for twelve seconds before ending, which is indicated by Palutena blinking. Lightweight also doubles the damage received, but knockback remains unchanged
Lightweight provides Palutena great mobility options for approaching and recovery, as well as follow-ups to many moves. However, it is a high-risk move due to doubling the damage dealt to her, making it easier for her to take damage, and subsequently KO'd. In addition, it cannot be used for ten seconds, and for the first five seconds her grounded mobility is reduced drastically, hindering her grounded approach during that time.

Lightweight is a power in Kid Icarus: Uprising. Like in the original game, Lightweight in Smash 4 will allow the user to move faster and jump higher; however, unlike Uprising, when used in Smash 4 the move will cause Palutena to be launched farther, whereas Uprising had the user taking more damage from enemy attacks.
