Dynamite Headdy

Dynamite Headdy (ダイナマイト・ヘッディー) is a video game released in 1994 by Sega and produced by Treasure. It was released on the Sega Mega Drive/Genesis system, with ports to the Sega Game Gear and Sega Master System. A port for the Sega 32X was planned, but due to the system's low popularity, the port was canceled. It was released for the Wii's Virtual Console on July 30, 2007.

The style of the game is platform/action. In the game the player controls the star puppet Headdy who can attack his enemies by shooting his detachable head at them.

Dynamite Headdy is one of three games included with Gunstar Heroes: Treasure Box Collection, a compilation of Treasure-produced Mega Drive games for the PlayStation 2.

The game made its latest appearance in Sonic's Ultimate Genesis Collection (AKA Sega Mega Drive Ultimate Collection) for Xbox 360 and PlayStation 3.

Storyline
Headdy, the central protagonist of the game, arrives in North Town to find that the evil puppet King Dark Demon is in the midst of attacking the puppet town to select which of the peaceful toys should live and which should be converted into his evil minions. Headdy is captured and rejected by D.D.'s forces, and is dropped into the dust cargo to be thrown into the incinerator. However, Headdy escapes the clutches of Dark Demon's minions and sets off to defeat the evil king.

However, trouble is afoot. Not only is the puppet world filled with Dark Demon's minions, but to reach the evil overlord's castle Headdy must defeat Dark Demon's Keymasters, who serve as the king's elite guard. To make matters worse, Headdy is followed by Trouble Bruin (Maruyama), a puppet jealous of Headdy's success. Trouble Bruin wants to be the star instead of Headdy, and will stop at nothing to get rid of him.

Gameplay
The game is played over a series of "scenes" and "acts" like Sonic the Hedgehog, the end of which is often typified by a big boss battle. Headdy's special ability is his launchable head. This can be fired in eight directions: up, down, left, right, and the four diagonals in-between. Launching it at enemies can damage or destroy them.

His head can also be used to hold on to a "HangMan", a character that acts like a hook. By grabbing a HangMan with his head, the player can then use it to hurl itself in its direction, as if connected by an elastic band. Headdy can also swap his head for a special head, if he attacks a HeadCase. Depending on the symbol that the HeadCase is showing, Headdy will get a different head with a different special power. Some of these powers include making Headdy's attacks stronger, becoming temporarily invulnerable, shrinking in order to reach smaller spaces and sucking up all items and enemies on screen. During flight stages, Headdy can switch between three types of flight head. Collecting a Bonus Head enters a bonus stage which, if cleared, gives the player part of a keycode which, when inputted at the end of the game, grants access to a secret ending.

Scattered across the levels are a number of Secret Bonus Points. These can be collected by performing a strange or skilled action, such as finding a hidden item or defeating an enemy using a certain tactic.
