Nosedeenians, colloquially known as Megawhatts, are mischievous little creatures composed of electrical energy who have the physical form of anthropomorphic batteries from the planet Nosedeen Quasar.
Nosedeenians are black and yellow or white with plus and minus symbols on their back, similar to a battery, and a lightning bolt on their chest. They stand roughly a foot tall, have pointy legs, and have three fingers on each hand. Their language consists of a series of high-pitched squeaking and chirping noises, however, they are capable of speaking English.
Nosedeenians can control electricity and can inhabit electrical devices, controlling them from the inside. Being made from electrical energy, they are weak against things that ground it (water being a chief example) and they are powerless against insulators. They grow stronger by absorbing electricity and can multiply if split in half or have enough power. It should be noted that when the one Ben first encountered split, both it and its clone seem to be surprised, as if they didn't know they were capable of doing it. It should also be noted that Nosedeenians are surprisingly strong for their size, as just one was able to lift Max Tennyson, who is many times its size, into the air by his underwear and giving him a flying wedgie. Another notable ability of theirs is that the noises they normally use to communicate can, at a certain pitch and volume, shatter glass.
Nosedeenians exist to have "fun", which in their case is to cause trouble wherever they go. While they cause a lot of damage, Nosedeenians do not seem to be evil, and in fact are not openly hostile to humans, merely lacking any self-control or sense of the danger they may be causing. They only openly attack after provoked.
