Mr. Nobody

"Caterpillars can turn into butterflies, can't they?"

- Penny Robinson, commenting on Mr. Nobody's transformation.

Mr. Nobody is the name given to an intelligent life form which once inhabited a cave system on planet Priplanus.

Biology
A phenomenally powerful being; nothing is known about Mr. Nobody's origins or real nature. When he was first found by Penny Robinson in 1997, he appeared to be a non-corporeal intelligence inhabiting a cave system; his memories dating back to the time of the planet's formation. Yet, despite his age, his personality was childlike. He was unfamiliar with many concepts, and unaware of his own identity.

Despite having no detectable physicality, Mr. Nobody can speak (possibly by telepathy) and manipulate the world, moving objects around both inside the cave and in the surrounding environment. His telekinesis can affect rocks, vegetation and water. He can make boulders light enough that a Human child can move them with ease; or heavy enough that even the Robot can't. He can also create earthquakes and destructive storms, which the Robot's sensors identify as "pure cosmic force with antimatter core".

History
In 1997, 11-year-old Penny Robinson from the Jupiter 2 mission wandered away from the ship and found a river where the water seemed to magically levitate towards her when she wanted to drink it. As she entered a nearby cave, a voice started echoing her words, trying to establish communication, and thus the disembodied intelligence was discovered.

Despite his alien nature, Mr. Nobody was friendly towards Penny. In her next visits, she taught him to "put words together" and speak more coherently, and taught him the meaning of new words, including "care" and "die". She found that her friend was an ancient being; his memories dating back to the formation of the planet; but he knew nothing of his own identity and thus the name "Mr. Nobody" became his moniker. Penny theorized that the mysterious alien might be "growing up" or "changing" in some way.

Interested in the diamonds that Penny brought back from the cave, Dr. Smith followed the girl and tried to impersonate the voice, believing that "Mr. Nobody" was just an imaginary friend, but hoping to convince Penny to bring back more diamonds. At the same time, the real Mr. Nobody provoked a tremor and closed down the entrance of the cave, much to the dismay of Penny, who didn't know why the alien had suddenly gone silent. Smith didn't give up on the diamonds, though, and later convinced Major West to help him set up explosives to access the cave's interior.

When Penny became aware of this plan, she rushed to warn Mr. Nobody, who remained unresponsive. The explosion set off by Smith and West knocked Penny unconscious. When Mr. Nobody awakened, he mistook her for dead.

The apparent death of his friend infuriated Mr. Nobody, and caused him to manifest outside the cave by raising an antimatter cosmic storm to destroy Smith and West, along with the entire Jupiter 2 crew. Fortunately, Penny regained consciousness in time to talk to him and tell him to halt the attack. The realization that he loved Penny as a friend coincided with Mr. Nobody maturing into his final form: a new galaxy shining in the night sky, bidding farewell to Penny as he left the planet.
