Blockhead Bowser

A figure of Blockhead Bowser from Mario Party DS.

Blockhead Bowser is one of Bowser's forms, and the final boss of Mario Party DS. It is a collection of blocks that form in three different ways - a top, a huge block, or a trail of blocks. The form is impenetrable, except for the one golden Bowser Block, which has to be attacked by the player in order to defeat Bowser. Bowser transforms into Blockhead Bowser via the Megamorph Belt. There are three types of blocks that Blockhead Bowser consists of: regular grey blocks, which release fire during the top form, Bowser Blocks, which can shoot out flame balls in all forms, and the golden Bowser Block, the weak spot, which can also shoot out flame balls, but in the trail form.
