Zeke, Lenny and Oscar are the (former) primary antagonists/primary protagonists (Alongside Russell Collins) of 20th Century Fox's 2018 feature creature film.
Zeke was among the few in his pack that had survived an attack by a human tribe, and, along with two others in his pack, Lenny and Oscar, was upset by Soto's decision to attack the humans instead of move south, where they could take their pick from hundreds of animals to prey on. The pack's lieutenant, a male saber named Diego, stepped up to announce that they would attack the humans at dawn, which irritated Zeke all the more, and prompted Oscar to question why they should take orders from Diego and not Soto himself.
Zeke, Lenny and Oscar met up with Diego, along with the others in his pack, at Half Peak, where Zeke reminisced on the joys of mammoth flesh, much to Lenny's displeasure. Lenny demanded that Zeke would stop reminding him of food, for Lenny was hungry, and was about to hit Zeke when Soto intervened, telling them all to save their energy, as mammoths don't go down easily. Soto was planning an ambush on Manfred, who must be caught by surprise, and so, he ordered the others to not attack, until they saw Manfred. Diego secretly turned on his pack after he had been shown real compassion and caring from Manfred and Sid that he had been leading into an ambush, and so Diego tempted Zeke to leap into action and to attack. The surprise being given away, the saber-tooths pursued Sid, as he slid down a snowy slope on a piece of bark. Soon after, Oscar, Lenny and Zeke, who had been chasing Sid, were impeded by a large log, that Manfred threw at them with his trunk. Once Oscar and Lenny came to, they rejoined their leader and attacked Manfred, cornering him for Soto to deliver the killing blow. Diego intervened against Soto's attack and was mortally injured. Manfred then struck Soto with his tusks when the saber was distracted and Soto hit a wall of ice and a number of icicles came down on him, killing him. After seeing the death of their leader, Oscar and Lenny left the scene quickly.
