Dragon Kirbos are one of the most, if not the most, powerful kirbos to have ever existed. They have many powers that other kirbos only dream of having.
Dragon Kirbos have the natural ability of flight, which is already incredibly useful for traversing long distances. They also have the ability to breath fire, water, ice, plasma, toxic waste, and much more. They can also manipulate space-time to an extent. For example, they can't time travel, but they can teleport using wormholes and can use hammerspace-infused containers to store abnormally large objects, but most cartoons also follow that same principle.
