She was the deuteragonist of The Meltdown, a major character in Dawn of the Dinosaurs and Continental Drift and a supporting character in Collision Course. Ellie is voiced by Queen Latifah.
It was revealed that when Ellie was young, she was separated from her herd during the ice age. She came across two opossums named Crash and Eddie, along with their mother. She later forgot her origins and thought that she was an opossum.
Initially Manny was overjoyed that he had found another of his kind, but got somewhat dismayed when he realized that Ellie believed that she was an opossum. Nevertheless, he and his herd (or rather, Sid) welcomed Ellie and her brothers to travel with them. During this time, Ellie displayed the mannerisms pertaining to an opossum as well as insisting (despite obvious proof that she was not a possum) and this tested Manny's patience, namely when she claimed that the act of bravery that he had done of fighting off the sea reptile Cretaceous was dumb.
Soon, Manny got his time to be alone with Ellie when he and Ellie went for a walk through a wooded area, where Ellie had a flashback that told her of her past. Upon remembering this, she knew that she was a mammoth. When Manny later implied that they must mate in order to save the mammoths from extinction, she was initially angered, but in time she apologized for overreacting.
Soon, however, this new "herd" reached a horrible obstacle between them and safety from the oncoming flood: a field of geysers, which Manny explained must be crossed, but Ellie would not listen: she and her brothers felt that they must go around. But this proved to be disastrous: as they were trying to reach their destination, some rocks caved down and nearly crushed Ellie and her brothers, but trapped them instead in a sort of cave. Manny rescued Ellie, for the water was flooding into the cave where she was trapped and had nearly drowned Ellie. She and Manny escaped and regrouped with the others, but faced another problem, for the waters were still rising.
After the waters had subsided a herd of mammoths made their way into the valley. Manny thought that because the mammoths had come, that Ellie would not want to remain with him. He was persuaded otherwise by Sid and Diego and confronted Ellie confessing his feelings, saying that he wanted to be together not because they had to be, but because he himself wanted to. Ellie accepted him as her mate. The mammoths trumpet while Manny and Ellie embrace. Manny and Ellie decide to stay with their old friends, taking along Sid, Diego, and the possum brothers.
Dawn of the Dinosaurs
In the third movie, she and Manny are mates and Ellie is pregnant with their first child. When they find the Dinosaur World under their feet, they have to go in and search for Sid in Lava Falls. When very close to Lava Falls, Ellie goes into labour, and gives birth to Peaches (which was named after the codeword that was for if Ellie went into labor on the trip). When they return to the surface, Ellie introduces Peaches to her new home.
Ellie is more supportive of her teenage daughter being on her own than overprotective Manny is (though in his defense, given what happened to his last family, it's completely understandable). When a landmass separates her and Peaches from Manny, Peaches starts sobbing since the last thing she and her father did was fight, but Ellie calms her down promising her that Manny will return as he is "the toughest most stubborn Mammoth I've ever met."
Ellie take charge of the animals, directing them to go to the land bridge, as Manny had told her. On the way there, Peaches was so depressed that she was almost caught in a landslide, but was saved by Louis. That night, she was visited by Ethan, who invited her to join his group the next day. Peaches excitedly agreed, even when Ethan told her to "ditch the molehog." Not even Ellie's advice about not letting a boy change her affected her mood.
The day after, Peaches watched with regret as Louis sorrowfully walked on his own. She talked to Ellie about her mistake, and her mother assured her that she would find a way to "make things right." It was then that they finally arrived at the land bridge, only to find it destroyed.
At some point afterward, the animals were captured by Gutt and his crew. Gutt held Peaches hostage in order to lure in the returning Manny. When all seemed lost, Louis intervened, distracting Gutt with a challenge and slamming a chunk of ice onto his foot, allowing Peaches to Escape. As Shira tried to Untie Ellie, Squint attacked and Ellie stomped him to the ground, flattening the rabbit like a pancake.
When the battle against the pirates started to turn in the herds' favor, Gutt then attempted to kill the bound Ellie, cutting off Manny's path by disconnecting the ships. Peaches, using her "half-possum" skills, gave the evil ape a powerful kick, sending him to the ice wall, saving her mother just in time. As Ellie and Peaches tried to escape, Gutt blocked Manny's path. Ellie and Peaches could only watch as the land mass Manny and Gutt on rose hundreds of feet high, leaving Manny up for the final confrontation against Gutt.
After Manny defeated Gutt, Peaches thanked Louis, who echoed "No matter what, you never leave a friend behind." Taking Gutt's ship, the herd travelled to a new home. To her delight, Peaches was encouraged by her father to explore and have fun. Ellie assured to Manny that both him and Peaches are going to be just fine.
Years later, Ellie slid onto a hockey rink, after her daughter had beat her husband at hockey, with their friend, Granny, holding onto her tail. Peaches' fiancé, Julian, a fun and loving mammoth, gave Ellie buttercup flowers, which Ellie loved. She watched as Julian gave Manny a giant bear hug, which Manny was uncomfortable with. Ellie remarked that Manny needs to get used to it. Peaches was about to leave, but Ellie reminded her of "the thing". Manny said he can do "the thing", but Ellie quickly said no, and told him to hang out with his friends. She then wiggled and giggled, and went to go decorate for her anniversary party with her daughter.
After it was done and Manny walked into the area, with fresh cut logs with fruit in them, Ellie and the other ice age mammals jumped up from their hiding places. Crash and Eddie chanted Manny's name, along with all the other ice age mammals. One called out that he forgot, and Ellie became sad and disappointed. Manny, trying to think of words to say, say fireworks brighten the sky. Ellie, surprised and amazed, like the rest of the animals, watched. She asked him how he did it and Manny, though he didn't do it, said he couldn't reveal his secrets. Julian commented to Manny and Ellie that he would miss them so much when Peaches and him left. Peaches then choked on her apple, and told Julian she hadn't told them. Manny and Ellie were shocked. But, not long after, Diego told them that they had a problem, an asteroid heading toward them. They ran and hid in an ice cave until it was over.
When they got out the cave, their friend, Buck escaped the dino world and became the leader of the herd, taking them through, to a crash-site. They followed Buck into a forest where they were hit with an electrical storm. While Peaches was trapped by the lightening, Manny didn't understand why Julian wasn't helping her. He then broke the rock cliff, though Julian warned him. Manny and Ellie were stuck as the purple lightening zapped around them. Diego was able to save them. Buck went inside the forest, and saved a "baby." It turned out to be a pumpkin, and the herd thought it was rather strange. Buck named the pumpkin Bronwyn. Manny and Ellie decide to try and get Julian and Peaches to stay. With the help of Sid, Granny, Crash, and Eddie, Ellie tried to convince Peaches it was too dangerous alone. She had Crash and Eddie be Peaches' distressed kids, Sid be a beast, and Granny be evil. Peaches handled it well though. Buck told the herd to rest for the night. In the morning they found that Granny was gone.
Hearing Granny's yelling, they followed it and were lead to a crystal place called A prehistoric rabbit called Teddy. Brooke, a sloth, fell in love with Sid, even calling her squad of Minicorns. The minicorns tapped their hooves on the crystal floor, releasing the crystal hoverboards, to bring them to the Geotopian master. Once they got there, they were confused by him. The llama, called Shangri Llama, was very flexible and calm. Later, Sid broke the Geotopia wall, trying to get a crystal for his love. The Geotopians agreed to give up their crystals to save their lives. The crystals were put in a volcano and pulled the asteroid away. Manny and Julian bonded over helping put the giant crystal in. At Peaches' wedding everyone was well and happy. Brooke sang My Superstar.
Ellie was rather deluded in the first film. She consistently believed that she was a possum despite her obvious differences in both size and mannerisms from her brothers, Crash and Eddie and completely writ it off when Manny questioned otherwise. Ellie was equally as stubborn and thoughtless as Manny was although she was much more bubbly and jovial but still shared the same tragedies as Manfred, as a young mammoth she was orphaned and virtually alone until she was adopted by a mother possum. Although her brothers do drive her up the wall she is still protective and caring towards them. Despite not starting on the best terms as Ellie begins to accept her mammoth roots, Manny and her take quite a shine to one another until the end where the two become mates.
Given the third film, Ellie's personality remained virtually the same. She retained the same spunkiness and charm however she was much more caring and loving to her mate, Manny however she was very frustrated about Manfred's overbearingness about her and her child's safety, to the point where he tried "to baby-proof nature" which earned him a snarky "talk to the trunk." Eventually Manny became less worrisome over his child but still loved the two of them unconditionally.
However in the fourth film Manny very much acted like an extremly strict father, considering her his helpless child instead of a fully grown adult. Ellie was the only parent of Peaches who realised that as a teenager she needed her breathing room to develop into her own personal adult. Ellie was implied to have a dating history. The evidence to support this is when Peaches was depressed about having a massive crush on Lewis, who she though was the wrong guy for which Ellie replies "cute boys can whiplash you brain. No doubt about that." Implying the same thing that happened to Peaches has happened to her before in the past. Despite accepting her species as a mammoth, Ellie is also incredibly accustomed to her old possum routines, such as sleeping upside down using her tail.
Ellie is a female brown mammoth, she has a dark brown fur, small green eyes, red hair and a small tail, she has two long white fangs and she has a long brown proboscis with two large nostrils at the end of it.
