He looks quite similar to his nephew and many other crabs, as Alan is a triangular-shaped crab with the addition of a mustache and goatee. The only instance of his appearance is in sepia-tone. He is shown to have worn a safari suit with the jacket sleeves rolled up paired with a belt and sash, and seems to have been wearing what looks like a pair of black leather boots.
Alan was born to unknown parents with his sister Betsy Krabs.
Later in his adult life, he would become an adventurer. According to Mr. Krabs, his uncle spent his life exploring the ocean, searching for treasure but found almost nothing of value except for a map.
Seemingly having never married and without children, Alan died before the series began, leaving all of his belongings to his nephew.
