Nosedeenian

Nosedeenians, colloquially known as Megawhatts, are mischievous anthropomorphic battery-like aliens who are composed of electricity and native to the Nosedeen Quasar.

Biology
Nosedeenians are black battery-like aliens roughly a foot tall (~ 30 cm) with plus and minus symbols on their backs, pointy legs, three-fingered hands, and markings on their chests that resemble lightning bolts.

Although the markings on Nosedeenians' chests are traditionally yellow, they can also come in other colors. For example, Buzzshock has a green chest, Ben 10,000 and Ken 10's Buzzshock have white chests, and Bad Ben's Buzzshock has a mint green chest.

Powers and abilities
Nosedeenians can control and fire beams of electricity powerful enough to harm Humans and Tetramands, and can grow stronger by absorbing electricity.

Nosedeenians can inhabit electrical devices, controlling them from the inside.

Nosedeenians can multiply in one of two ways: either after splitting in half or obtaining enough power.

Nosedeenians are surprisingly strong, agile, and durable for their size.

Nosedeenians can fly seamlessly in the air and leave an electric trail while doing so.

The noises that Nosedeenians normally use to communicate can shatter glass at a certain pitch and volume.

Weaknesses
Being made from electrical energy, Nosedeenians are weak against water and other resources that ground it.

Nosedeenians are powerless against insulators. Similarly, their electricity can be absorbed by Conductoids and hybrid Terroranchulas.

Nosedeenians have a limit to how durable they can be before being knocked out by enemy attacks.

Like other organic beings, Nosedeenians can be banished to another timeline by a Chronosapien.

Culture and society
Nosedeenians exist to have "fun", which in their case is to cause trouble wherever they go. While they cause a lot of damage, they do not seem to be hostile, and only openly attack when provoked.

Language
Nosedeenians mostly communicate with high-pitched squeaking and chirping noises. Certain members are capable of speaking English, albeit in a form that sounds like a Human who has inhaled helium.
