Dededoo is a character in Brawl in the family that looks very similar to King Dedede, Kirby's friend and foe.
In his first appearance, (Comic #103) he comes to kirby's house to clean his clock. Of course, he means it literally, and does a great job. It is then revealed that Dedede and Dededoo are two completely different characters when they meet. Dedede also knows Dededoo, although their relation is not made clear.

Mr. Dededoo makes a few appearances later in the series.
