|“I love your mother's crumb cake!”|
|— Ed to Jay, Day of the Departed|
Ed Walker is the adoptive father of Jay Walker and the husband of Edna Walker, as well as the owner of Ed & Edna's Scrap N Junk. Ed is well known for his forgetfulness, which often results in him asking his wife to take notes for him.
Ed and Edna, visited Jay at the Ninjas' new headquarters, Destiny's Bounty. The Ninja welcomed them and gave them a tour, but Jay was embarrassed by his parents' antics and quickly shoved them out with a hasty promise to visit them sometime. Disheartened by their son's icy reception, Ed sadly told Edna that Jay had outgrown them—the time had come to let him go and live his own life.
When the couple returned home to the Junkyard, Ed went to work on the surprise he was building for Jay. He heard a noise and called Edna to make sure the security was on, although she responded that it must have been broken. They were suddenly ambushed by Lloyd Garmadon and the Fangpyre tribe, who infected several of the machines around the junkyard to transform them into Serpentine Vehicles. Ed watched in horror as his creations were mutated, only to be informed by General Fangtom that his minions' bite worked just as well on humans.
When the Ninja visited the junkyard the next morning, Jay found Ed and Edna bound together in an old freezer—worse yet, both of them were infected by the Fangpyre's Bite. The Ninja fought the Fangpyre, attempting to steal the Fangpyre Staff that contained the anti-venom to cure both Ed and Edna.
After the staff was retrieved, Nya cured Ed and his wife. After recovering, Ed used his mechanical expertise to fix the Destiny's Bounty's flight systems, enabling the ship to escape the Fangpyres. Jay told his parents that they would be able to return to the junkyard once things settled, but offered them to stay aboard the Destiny's Bounty for as long as they liked.
Ed and Edna attended the "Take Back Ninjago Rally" in Ninjago City, but fled to their car when the rally was interrupted by the arrival of the Great Devourer. Before they could escape however, they were surrounded by the giant snake, but were saved when their son arrived just in time.
After the devourer was defeated, Ed and Edna met up with the Ninja and congratulated Jay on his success.
He and Edna entered the Ninjaball Run competition, but they crashed in the Glacier Barrens when they helped Jay by giving him their fuel and a spare vehicle part to finish the race with a piece of them.
Ed and Edna were at the harbor before the Ninja sailed off in search of the Island of Darkness. As Edna advised Jay to eat his vegetables, she demanded Ed tell him the same, only for Ed to tell him to listen to his mother.
Ed was helping the Ninja find some parts. When the Nindroids started attacking, he and Edna left the junkyard with home-made jetpacks, leaving the others.
When the Ninja were framed, Ed and Edna were interviewed on why Jay would commit crimes. They denied the accusations, but only worsened the situation, saying unless it was for good reasons.
Ed returned to the junkyard after running from picking up a few things to find Jay there, heartbroken as he had received a letter that his father had passed. Ed and Edna then finally admitted that he was adopted and gave him the note they had received.
When Jay returns, once again, to the junkyard, he tells his parents about how helpless he was until Ed reprimanded him and tells him to find a few friends to assist him in stopping Nadakhan's wedding. As they watch their son leave, Edna said he was too hard on Jay, causing him to remark that it was why he married her.
When Lloyd recommended they would take the Jet, Jay tells him his father is fixing it. Ed had managed to get it fixed, but a butterfly soon landed on it, destroying it again, much to his annoyance.
