Alolan Exeggutor

Alolan Exeggutor is a Dragon/Grass-type Pokémon that was introduced in Generation VII as a variation of Exeggutor, known in Japan as Nassy, that is located in the region of Alola and evolves from Exeggcute when exposed to a Leaf Stone.

Pokémon description
Exeggutor resembles a coconut palm or other palm tree. Its legs and body resemble a tree trunk, and its legs are thick with two-toed feet and a light yellow paw pad on each foot's underside. It has leaves sprouting from the top of its body, and Exeggutor has three round, light yellow heads that resemble coconuts, each with differing facial expressions. Each head thinks independently of the others, so it makes a lot of noise as each head speaks its mind.

The Alolan variant form, unlike regular one, has a larger and thinner neck and a tapering tail with two leaves and a fourth head on the tip. Due to that, the people of Alola claim that Alolan Exeggutor is this Pokémon's true form.

In Super Smash Flash 2
Alolan Exeggutor is one of the Pokémon that can be released from a Poké Ball in Super Smash Flash 2. Once it is released, Exeggutor will use Dragon Hammer, heavily dropping itself onto the ground, damaging any opponents on contact and dealing high damage and knockback.

Trivia

 * Exeggutor also appears in Super Smash Bros. Ultimate but with a completely different effect where it act as large wall that divides the stage (therefore not performing any move from the Pokémon series) walking back and forth until it disappears.
