Name: Dubior
Debut: Kirby's Return to Dream Land
Kirby's Return to Dream Land is very realistic, because it accurately depicts the phenomenon that, when you go to space, you will encounter funny robots flying about! What is their purpose? We don't know! There is, however, a sort of controversy or misunderstanding revolving Dubior.
You see, Dubior grants the Spark ability. Because it is a robot that runs on electricity, and uses all sorts of electric attacks! However, many people do not like this, and think it should instead give the UFO ability.
Perhaps I am in the minority here, but I disagree! Dubior may be a flying machine in space, but at least to me, it does not seem all that much like a UFO! It is just a funny robot. The UFOs in this series have all had a very distinct design trend, which Dubior does not follow. Besides...
What is a UFO? An Unidentified Flying Object. Dubior is not unidentified. It's Dubior! It says it right there on its health bar! Objectively, Dubior is not a UFO. It is just a FO. And nobody says FO.
What Dubior HAS always reminded me of is those little handheld vibrating massagers! You know, the ones with a central round part and three or four orbs that vibrate and you rub it on your back? It is a fun thing to be reminded of!
Anyway, Dubior is a mid-boss, and a very special one! As Kirby and friends journey across Popstar, they will encounter various mid-bosses as usual, culminating in a classic Mid-Boss Tower Level in which they are fought one after another, each fight taking place higher in the tower.
This tower is so high that it pierces the atmosphere, and Dubior is fought last, on nearly the top floor! It is no coincidence that the most alien of foes is only on the closest point of this planet to outer space. This foreshadows that it will reappear, and more often, on the distant planet Halcandra! This seems to be where it was created, but for what reason? We don't know!
