Vine Whip
Vine Whip is Ivysaur's Up Special Move. With this move, Ivysaur send a vine out of his flower in order to do a Tether Recovery. Ivysaur will also gain a small amount of upwards distance. There are two "forms" for Vine Whip. The first is when Ivysaur is on the ground, Vine Whip being an attack that attacks at a forty-five degree angle in front of and above Ivysaur, with a powerful sweetspot at the end of the whip. The second is when Ivysaur uses it as a recovery, in which Vine Whip gains a deceptively long range, capable of nabbing the edge with a length far beyond the ground-based Vine Whip. Unfortunately, Ivysaur can easily be edgehogged while attempting to use the Vine Whip to recover.
Origins
In the Pokémon games, Vine Whip is a fairly standard grass type move. It is very frequently seen being used by Ivysaur and its evolutions in the anime.
