Guma

Guma is the Japanese name for an otherwise unnamed enemy from The Adventure of Link. These foes resemble giant bulls and constantly hurl chain hammers in an upward arc, making approaching them somewhat difficult. If Link can get under the arc of the attacks, he can strike without being hurt. They are common throughout Parapa Palace.

Captain N: The Game Master
A monster resembling a Guma briefly appears in the "Quest for the Potion of Power" episode of Captain N: The Game Master. As Link, Princess Zelda, and Kevin are making their way through the Parapa Palace, a Guma throws a hammer at Link's hand, which causes him to drop his sword. Before the Guma has another chance to attack, Kevin defeats the foe using his Zapper.

Trivia

 * Interestingly, this enemy's name can also be transcribed as Gooma, which is the name given by the translation team to a new boss exclusive to non-Japanese versions. Artwork used for Gooma actually seems to be art originally intended for Guma, also.
 * The Doomknocker is an enemy in the same game which has attacks that are similar to that of Guma. Its Japanese name (ヘルグーマ) translates as "Hell Guma."
 * The Guma's fighting style is also very similar to that of the Hammer Bros. from the Super Mario Bros. games, in that it occasionally stops throwing for a brief moment, leaps into the air, then continues throwing.
