*Gwen 10's personality is the same as her 10-year-old Prime Timeline counterpart. She tends to make sarcastic comments directed at the alternate Bens about some of their quirks or levels of intelligence while also being a very caring and courageous person who believes that family is the one thing that one should be able to count on above anything else.

Gwen 10 is usually analytic about situations and mysteries if and when there is time. However, she can be ready to charge into action head-first when the circumstances call for it or when her family seems to be threatened.

Unlike Ben, Gwen does not name her Omnitrix's alien forms.

In Gweniverse, when the Omnitrix fell to Earth at the Yosemite National Park while Gwen, Ben and Max were camping there on the first night of their summer vacation, it was Gwen who found the Omnitrix.

In Ben 10,000 Returns, Professor Paradox referenced this Gwen's timeline as one of the alternate realities that exist while explaining how cross-time works to Ben, Gwen, and Kevin. Gwen's playlist mostly consists of aliens introduced in the Original Series. Unlike the Prime Timeline's original Omnitrix, her Omnitrix had Cannonbolt and Wildvine as part of the original 10, while Ben Prime unlocked them separately. This is similar to the reboot's Omnitrix, which also started with them. She also has Goop in her Omnitrix, who was locked for Ben Prime at that time. Like some of her other alternate counterparts, Gwen 10 is not an Anodite. Likewise, she cannot transform into an Anodite using her Omnitrix. Gwen 10's aliens were all designed by Derrick J. Wyatt and Chap Yaep. Gwen has only just started as a hero, and does not have an archnemesis yet. Similarly, she has not met her reality's version of Kevin yet. Gwen 10 can get control of Alien X easier than Ben Prime can.*
