After Wade killed Ajax he and Vanessa reunited while Colossus and her left with Negasonic finally acknowledging him as cool.
to be added
Negasonic Teenage Warhead is pretty much exactly what the opening credits of the movie said she is: A Moody Teen. She is sarcastic, unmotivated, very antisocial, and even her outrageous mutant name is a good indicator of how little she cares what anybody thinks of her. There really isn't anything particularly endearing and heroic about her besides the fact that she is on the side of the X-Men, among other "heroes". Although she remains obedient to her chivalrous teacher, she treats her duties as a hero mostly like chores she cares little about, and would even take a moment to write a Twitter post on her phone right at the start of a battle.
Besides her super human abilities, she is no different than a normal angsty teenager. She is snarky, rude, and isn't afraid to insult people whom she doesn't like, especially Deadpool. Though she does eventually warm up to him, calling him "cool." She does crack a smile at some points, especially when Deadpool makes a fool of himself.
Powers and Abilities
Explosion Creation & Manipulation: Negasonic is capable of generating explosions from her body of varying degrees. She can create a strong enough blast to push a van sideways with enough force to crush a human or a blast capable of toppling a grounded hellicarrier, as well as create a downward explosion capable of launching herself high into the air. She can even use her explosions in conjunction with a full body charge to attack superhumanly strong opponents like Angel Dust. Nega-Sonic does seem to require a certain amount of concentration and 'charging' time in order to better control the size/shape/direction of her explosions. Momentum also appears to play some part in the overall force and general direction of her explosions.

Behind the scenes
The original draft of the script had a lot of gun play and sword play, and director Tim Miller said he wanted to see more in the way of superpowers and traditional superpowers. As the writers looked for more characters, the name Negasonic Teenage Warhead jumped at them "because it was so cool, but we ultimately ended up changing her powers from the comics." In the comics, Ellie's powers are Telepathy and Precognition. Instead the writers went for exploding powers similar to Nitro - "We changed her to having this kind of explosive… because just the sound of the name - "Warhead" - implies to us that she could kind of become a human bomb, and we ran with that. There will be a few people offended by that, but she wasn’t a major enough character that I think we won’t piss too many people off." It was the only thing the writers required Marvel's permission to do, asking Kevin Feige directly.
- During San Diego Comic-Con 2015, Brianna described her character as a "15 year old superhero in training".
- Ellie can be seen wearing an 'X-Men' uniform similar to the one from X-Men: First Class.
- Brianna Hildebrand created a rock playlist for Ellie, which for obvious reasons included the song which inspired her codename (along with others by its band, Monster Magnet).
