Victor is an extremely elderly crab, at least over 90 years old, with a lightened pink shell and wrinkles. He has a large bushy gray mustache, and wears a turtleneck sweater with light blue edges and a pink and light blue diamond pattern, a white shirt, and purple pants. He also seems to speak in a pirate accent much like his son.
Victor Krabs was born to the pirate Redbeard Krabs and Grandma Krabs.
He might have been born in Bikini Bottom, as he has a few ancestors that live in the area in which the city is located.
At some point, he married Betsy. The two had at least two children: a daughter and Eugene H. Krabs. When Eugene was five years old, Victor gave him a dollar.
It was implied that he died before Eugene started his restaurant with Plankton. However, in "Senior Discount," Victor Krabs is shown to be alive and makes his first physical appearance.
He may be divorced from Betsy Krabs, since she was seen dating Plankton and his giant robot.
He has not been seen interacting with his granddaughter or grandsons.
