Ben 10 Gwen Tennyson

In the original series, hate Gwen share, a love affair with Ben, insult humor and dry sarcasm most of the time, partly because of their shared birthday. She uses her laptop on the lookout for strangers and / or creatures they might encounter, is a capable gymnast and has trained in the martial arts. It has also shown almost an innate skill in dealing with different devices or complex objects, as in "What If?" Episode "Gwen 10", when Gwen gained the Omnitrix instead of Ben and proved much more clever in its use, as it was originally.
