We tend to compare the dwarf with Jupiter. Which implies a huge question.
Can Jupiter become a Sun? there has been a Nuclear reaction in Jupiter in 2003.



What im getting to is, The possibility of Jupiter becoming a new born star is possible within the scientist. The black Spot in that picture, is the cause of the nulcear reaction.

Planet X if it holds any extraterrestrials, and if it were a battlefield, with nuclear power. Than that could have easily explain why it is a dwarf. Due to the nuclear reaction.

Do you mind telling us which of these two statements is the current theory? There is a whopping discrepancy you've got to explain there.
-If planet x would be the size of Jupiter, than i really wanna ask a question how did it become a dwarf.
-So the only explanation acceptable would be that its bigger than Jupiter. For planet x to become a dwarf. Due to its enormous size full of gazes.
