Ralph Domzalski is an unseen character mentioned a few times in Trollhunters. He was Nancy's son and Toby's father who, along with his wife, became lost a sea when their cruise ship got caught in the middle of a storm.
When Toby was about two years old, Ralph and his wife won the state lottery. To celebrate, they both then went on a cruise together around world, but there was a storm, which they unfortunately got caught in. And were presumably killed as Toby mentions that his parents never made it back.
