Hidon

Hidon is a green Piranha Plant with a red stalk that is disguised as a green Treasure Chest in Super Mario RPG: Legend of the Seven Stars. His name is a play on "hidden", referring to how his true form is enclosed within the chest until Mario strikes it from below and initiates the battle. Hidon also shares his name with a boss in Final Fantasy VI, another game by SquareSoft. Unlike the other enemies found in treasure chests in the game, Hideon is only encountered once in the game. After defeating him, the player receives a large amount of experience points and coins, and can then find the Safety Badge inside Hidon's now-vacant treasure chest. For some reason, it has eyes when hiding in the chest.

Like his lookalikes Pandorite, Chester and Box Boy, Hidon is a powerful opponent, having both high attack and defense, as well as high HP and immunity to Thunder, Fire and Ice and all status ailments, although Mario's Jump attacks are very effective. Hidon's first action in battle is to release four Goombettes that are trapped inside of the chest ("Monsters are inside!") to assist him in battle; once they are all defeated, he releases another set.

If Hidon is targeted with a normal attack, he either attacks in return, or uses Carni-Kiss, which allows him to bite a party member for 2x the damage of his normal attack. The odds of each is 2/3 in favor of casting one of his normal attacks (Static E!, Willy Wisp and Flame Stone), and 1/3 in favor of using Carni-Kiss.
