Nebulus, the living Nebula.
Nebulus was born a human in the country of Tibet. He was a monk whose expertise at astral projection was legendary. One day a jealous rival murdered his human body whilst he was roaming the stars in his astral form. The monk’s mind was lost for a time until an advanced alien life-form discovered and took pity upon him. In an unfathomable process, the alien merged the monks mind with the gas cloud in which he had been found. Thus was Nebulus born.

He can manipulate and project the gases/dust that comprise his new “body”. He can also be any size he wishes although he prefers human size as that is what he was used to on earth. (and it’s easier to avoid collateral damage, you don’t want to crush the city you are trying to protect)
The silence in here is deafening! Guess I’d better make some noise…......
“In the year 1937 Scientists picked up a strange signal from outer space, it took 20 years to decipher. It simply stated ‘We are here’ and gave a set of Galactic coordinates. World Governments were reluctant to inform the populace,but a response was prepared. The source of the transmission was determined to be a star system 10 light years away and in 1950 Humanity replied: ‘We are here, you are not alone’.
In 1965 another transmission was picked up, it said ‘We are coming’.
They are almost here.”
