Agility
Agility is Pichu's Up B move. When performed, he will make a quick teleport-like action in any direction. Inputting another direction during this first teleport allows Pichu to immediately perform a second teleport upon finishing the first. Unlike Pikachu's Quick Attack, any enemy caught at the mid or end point of these teleports will not be dealt any damage. Pichu will also be dealt 1% damage for the first teleport and 3% if he uses the second teleport.
Origins
In the Pokémon games, Agility greatly increases a Pokémon's Speed, and can be stacked up to 3 times. Competitive battlers usually make it so that after one Agility, the user is faster than most other Pokémon, ensuring that they go first.
