6ball

6ball (also know as Alienball) is the caveball depicting extraterrestrials. There is currently no proof of his existence besides crop circles ​ (Those are fake.) But Universeball is so huge it's highly improbable that he doesn't exist anywhere. https://www.youtube.com/watch? v=hAAlDoAtV7Y Whether or not he has visited  Earthball is another question though.

According with the movies made by USAball, the 6balls comes to Earth to talk with Earth "leader", the USA president  ... and only will attacks the USA cities, knowing that earth civilization centers around them.

The Problem that another countryballs find that this is a complete lack of modesty of USA, because USA president is only the leader of ... USA. Russiaball and another countryballs will probably have this reaction:

And the aliens probably don't see any difference between countryballs and citiesballs of the world (they have no prior knowledge of Earth societies). For example, the 6ball don't see any difference between New Yorkball, Tokyoball, Moscowball, Berlinball and Parisball. They will probably invade and destroy all of them, at the same time until the Earth countryballs upload a virus onto 6ball's ships and takes them out using only a biplane with a missile duct-taped to them.

6balls never calls the countryballs by their names, always calls them "Earthling" or "Terran", regardless of whether is a world power or an irrelevant micronation, as they dont really know about Earth boundaries and territories nor dot hey have the time to figure out these territories.

But they can differentiate them by characteristics: "Earthling stuck on Earth" (Polandball), "Earthling with sun shades" (USAball), "Earthling with hat" (UKball), "Earthling with Slant Eyes" (Japanball), "Earthling that plays football" (Brazilball), "One-eyed Earthling"(Serbiaball), "Drunk Earthling" (Irelandball), "Earthling that don't laugh or Earthling that like anschluss" (Germanyball)... etc.

Also has been visiting Earth for a while to help Naziball with his aircraft technology but pfftt? theres no aliens and would they really be interested in helping a bunch of primitive nazis?

He saved the World from an Nuclear War, but that Earthling with Sunglasses told that to the World.

it is believed that he as also Nukes and Radioactivity can't harm him, but that depends on the race or civilization he represents.

He also can represent all sentient life beyond Earth as there can be many different types of alien races and civilizations.
