Gwen Tennyson (Classic)/Neutral

===Charmcaster===
Charmcaster developed a grudge against Gwen in the Original Series, because Gwen stole her spellbook and learned magic easily.
In Alien Force, Charmcaster exacted her revenge on Gwen by kissing Kevin and subsequently putting his mind under her control.
Their relationship in Ultimate Alien initially did not change, until Where the Magic Happens, when Charmcaster teamed up with the team in Legerdomain. The two bonded through their experiences and combining of their powers, with Gwen coming to sympathize with Charmcaster when learning of her origins.
In Enemy of My Frenemy, the team returned to Legerdomain to help Charmcaster. However, Charmcaster's long time trapped in Legerdomain had corrupted her, and she temporarily killed Ben, Gwen, and Kevin to resurrect Spellbinder. When Spellbinder refused to come back to life at the expense of others, she became saddened by that, and her life became empty and lonely. Gwen let Charmcaster go rather than have her apprehended, revealing she didn't hold a grudge against her for her betrayal afterwards, but instead felt even more sorry for her and worried about how she would be able to move on after this trauma. This pity was maintained in Couples Retreat, where Gwen was very concerned about Charmcaster's well-being when Charmcaster fell in love with Darkstar and tried desperately to convince her that Darkstar was merely using her for her power. At the end, the two had a truce and Charmcaster gave Darkstar over to Gwen to beat up.
In Omniverse, Gwen first saw her in Charm School, where she attended class with her, conducted by Hex. Charmcaster wasn't there to go after Gwen though, but her uncle Hex. She double crossed Hex and turned him into a totem in order to claim the Staff of Ages. Gwen tried to talk some sense into her, telling her that she was not a bad person but was damaged and needed help, which started a magical battle between the two sorceresses. Gwen was overpowered by Charmcaster and was tired. They had a long fight around the university until the team of Ben, Kevin, Rook and Zed helped to lead her to the library. Gwen holding the Hex totem in the library allowed her to become more powerful and she sent Charmcaster and Hex to Legerdomain.
In Third Time's a Charm, Charmcaster turned Gwen into a totem and put her in her bag with Addwaitya, Darkstar and Hex. Gwen managed to use Charmcaster's lipstick to draw in her bag. Ben tricked Charmcaster (who had turned into a dragon) into touching the magic in her bag and was turned into a totem. Gwen, Hex, Darkstar, Bezel and Addwaitya were free, with Darkstar being arrested but Addwaitya escaping. Gwen kept Charmcaster, who was now inside her own bag, in her room. Gwen happily said that under these circumstances of Charmcaster being rendered harmless, she and Charmcaster could finally become friends, as she patted the bag with Charmcaster in it fondly.
