Captain Shaw is a fisherman who believes in the existence of the Krakken.
He has greyish-green hair on both the sides of his head as well sideburns. His chin is stubbled. He is wearing a regular tan fisher jacket and olive pants. He has a red baseball cap with a tan rectangle on it.
Despite being depicted as "crazy" he still makes a living by giving rides on his boat and fishing opportunities. While he seems obsessed with getting the Krakken, he chose to save Ben rather than kill it.
He was first seen in The Krakken, where he took Ben and Max on a fishing trip. After Ben mentions the Krakken, Shaw takes them to a spot where he thinks it will appear. However, the spot is fenced off by the Friends of Fish. Shaw wants to go through the fences but then Jonah Melville and his crew appears and asks him to turn back. As they are heading back, one of Shaw's radars goes off. The Krakken suddenly appears and attacks Melville and his men. Ben fights the Krakken as XLR8 and saves the Friends of Fish.
After Melville shut down the whole lake he still doesn't give up and sails to the lake once again. Ben sneaks up to the ship too. Shaw and Ben dive into the lake and notice a Krakken egg. Shaw swims up to the surface and gets taken by Melville. They blow up his boat. Ben turns into Stinkfly and after a fight he manages to save Shaw.
Shaw is seen again fishing in a small lake in Monster Weather.
