*Gwen Tennyson is the President of the United States of America and is leading the resistance against the Xerge threat. According to General Hex and A.I. Max, she has not spoken to Ben 10,000 for years.

In Ben 10,010, President Gwen Tennyson states to the military under her leadership that they must take action. General Hex offers to recruit an "alien ally" to help combat the threat as it reaches Bellwood. Gwen later attends a press conference, accompanied by Secretary Zombozo, before the Xerge attack. Donning a battle suit constructed by Sergeant Steam Smythe, Gwen goes and battles the Xerge. Hex eventually arrives with Kevin, still trapped in the form of Humungoraptor, and he and Gwen battle the Xerge.

Later on, Ben 10,000 arrives at the White House, and Gwen is once united with her cousin. The Xerge attacks the White House, and Gwen evacuates along with the others while Ben, Kevin, and Hex fight them off. Gwen soon returns in her battle suit, and after being convinced, she lets Ben 10,000 use the discarded time travel project to go back to the past to seek help.

As Ben 10,000 went back in time, Gwen fought non-stop against the Xerges until her cousin arrived to fight with help. Upon realizing that Ben had brought his younger self into the future, Gwen argues with him about the temporal dangers that this could generate, until she is interrupted by the Xerges who reveal that they were on Earth to get his DNA from the Omnitrix. Gwen tries again to fight the aliens using armor improvements given by Hitch, but nothing works, until the two Bens understand each other and manage to use the Surge to defeat the Xerges once and for all.

After the defeat of the Xerges, Gwen began the renovation of Bellwood, in addition to making passes with Ben.*
