Constellation:

Character:

King Nikochan is the king of an alien race named the Nikos. His race have their butts on their heads, their nostrils on the tips of their antennae, and their ears on their feet. He wishes to take over the Earth but his ship always breaks down. In the manga, he speaks in Central Nagoya dialect, in which a native speaker of the dialect will find distinct from the author's Northern Nagoya dialect. In the anime, he speaks in a false Nagoya dialect. He is always accompanied by his unnamed sunglasses-wearing servant. Unlike King Nikochan, his servant seems to be much smarter/sensible than the King.
