Gwen Tennyson (Classic)/Allies

===Cooper===
Cooper has had a crush on Gwen ever since a flashback in From Hedorium to Eternity, though the feeling is not mutual. Cooper was called in by Ben to create the Surveillance Spider to spy inside Thaddeus J. Collins' house. Cooper was initially reluctant, but changed his mind after he heard Gwen's name. As Cooper worked on making Kevin more mobile, Kevin taunted him over his crush on Gwen, telling Cooper that he was the better guy.
Four years later, when the team recruited Cooper for the final battle against the Highbreed, Cooper happily agreed. He also expressed a distaste for Darkstar after he referred to Gwen as "Lovely Gwen".
When Kevin had mutated into Ultimate Kevin, Cooper agreed to Darkstar's plan to create a device to power the Dominus Librium to revert Ultimate Kevin. Cooper later charged Ultimate Kevin in retaliation for attacking Gwen, though Ultimate Kevin outmatched him and tried to kill him, though he was saved by Ultimate Echo Echo. After they finally managed to revert Ultimate Kevin to human, Gwen kissed Cooper on the cheek.Absolute Power: Part 2
===Julie Yamamoto===
Due to Julie's relationship with Ben, Gwen and Julie have developed a very close friendship, spending time together by shopping or doing homework. Usually when Ben and Julie have relationship problems, Gwen usually comes to Julie's defense knowing how obnoxious Ben can be. For instance, when Ben expressed romantic interest in Eunice, Gwen reminded him about Julie, to which Ben stated that they had broken up (or, in Julie's view, might as well have been broken up).
When Ben doesn't help Julie, Gwen usually is the one to help her. For example, when Ship suddenly went to Monarch to help Baz-l, Gwen and Kevin offered to help her when Ben refused.Eye of the Beholder
On one occasion, Julie was in danger because the Vreedle Brothers were given a task to take Ship for a prize in return. Ship merged with Julie to protect her, but it wasn't enough. Gwen risked her safety to save Julie and fight them off together.
===Emily===
Emily has been Gwen's best friend since kindergarten. Emily often brings food to school for Gwen, knowing that she usually skips breakfast. Though she is understanding of Gwen's crimefighting responsibilities, she is also upset that they do not spend as much time as they used to. However, Gwen tries to support Emily to the extent possible, such as when she went to Emily's piano recital at the last minute after helping Ben and Kevin defeat Animo.
===Rook Blonko===
Gwen and Rook get along wellMany Happy Returns and talk to each other on occasion off-screen, enough for Rook to know when Gwen's birthday is as well as the history between Ben and Kai.An American Benwolf in London
Gwen, however, felt somewhat offended when Rook said that she is only attractive by Earth standards.Showdown: Part 2
Rook was worried for Gwen when he did not know about Kevin's whereabouts.The Rooters of All Evil
===Hex===
Hex used to be one of Gwen's worst enemies in the Original Series, bearing a grudge against her for foiling his plans for world domination.
In Omniverse, Hex reformed and became Gwen's favorite teacher at Friedkin University, the two of them bonding over their shared affinity for magic and mutual concern for the well-being of Charmcaster. Gwen defended Hex from Ben's constant accusations of still being evil, though she admitted that him giving her a B- was pretty evil of him.
