Fathom: "Having humans or any other dragons down here, with us, is new."
Gill: "And sometimes new can be good."
Fathom: "Sometimes."[src]

Fathom is a female Divewing. She first appeared in Season 2 episode "Divewings".


Protecting her Eggs

Fathom and her mate, Gill, made a nest in an underwater cave under Huttsgalor, where she laid three eggs. During the events of "Divewings", a large amount of trash that was dumped into the sea ended up in her nest and endangered her eggs. She immediately blamed humans and started attacking boats from Huttsgalor along with Gill. Her attack was intercepted by the Rescue Riders, who stopped her and Gill. The two returned to their nest, but they were followed by the Riders. Leyla and Summer entered the cave quickly afterwards, but were chased out by Fathom. All the Riders then entered the cave, where Fathom and Gill explained the situation to them. The Riders offered to help her clean the cave and find the culprit, to which Fathom agreed. She was reluctant to let Leyla get close to her eggs, and claimed that she never let humans and other dragons than her and Gill inside the cave. Upon finishing, she exited the cave along with the others and discovered more trash floating on water and getting close to her nest. She accused Leyla and Dak of lying and went to confront the danger herself. Fathom and Gill attacked Elbone's ship (who turned out to be the culprit), but could not stop the litter threatening her nest. Dak then had an idea and, with the help of Fathom, Gill, and Summer, used fishing nets to catch the trash. Fathom then personally thanked the Rescue Riders and forgave Elbone. She acknowledged that not all humans were bad, leaving the island along with Gill.
