*Shear seems to be the most successful and clever among the three aliens, collecting 3 out of the 4 of the Cosmos Stones that her group acquired.

Shear is devious and sneaky, and does not care what she does, as long as she fulfills her task, having no qualms about threatening people with dinosaurs or dangling swords to get the information or cooperation she wants. Shear uses a sharp-edged crescent boomerang-like object as a handheld or throwing weapon and to retrieve objects. Shear first appears briefly in episode 4 on the Space Pirates' Ship, when Spectre sends her to get the Yellow Cosmos Stone from Sophia after her comrades had both failed, and is "encouraged" not to do the same.

The next episode, she attacks the D-Team with a Yangchuanosaurus nicknamed "Yang", recalling it away from a hit by Thunder Storm Bazooka after grabbing Sophia.

She interrogates Sophia about the Stone and her brother Spartacus by dropping swords from the ceiling at her. She then confronts Spartacus in the Coliseum with Yang before the D-Team arrives. Venom Fang's Piatnitzkysaurus is quickly defeated by Chomp's Thunder Bazooka while Yang beats Ace and Paris with Burning Dash, but is eventually defeated after Chomp uses Dr. Z's newly completed Element Boosters to gain his DinoTector Form, using Ultimate Thunder. Shear losing its card (and the Venom Fang card). However, she ambushes Spartacus outside and snatches the Yellow Cosmos Stone.*
