Ado is a painter that lives in solitude at the edge of Cloudy Park, serving as its boss in Kirby's Dream Land 3. Ado's gender is technically not disclosed in any games, and from the limited appearances, it has been subject to divided opinions (see thecontroversy section). The manga refers to Ado as female, but that is not canon to the game continuity. However, it is the closest official supplement that confirms a gender, though the fanbase likes to suggest otherwise in a way to differentiate the character from Adeleine.
Ado is generally weak, and when she fights Kirby herself, she is defeated in just one hit. To make up for this, Ado attacks by creating a wide array of foes that Kirby must contend with beforehand. Most of the things she paints are very simplistic, but are still recognizable enemies from Kirby's past. All of things she paints during the battle are simply various bossesfrom Kirby's Dream Land 2. She is under the guise of Dark Matter and must be freed from its control after his defeat at the hands of Kirby. Because Ado paints so many foes during the fight, she is perceived as one of the most arduous and time-consuming bosses of the game. As such, Ado is fought late into the game.
Ado is best known for her uncanny resemblance to Adeleine, a green-clad artist who teams up with Kirby in Kirby 64: The Crystal Shards. This has spurned endless debate by the fans. Either way, neither Ado nor Adeleine have appeared since they debuted in their respective games. This may have been caused by the widespread controversy surrounding the two of them, and may have even been enacted to avoid more confusion.
