The Pirates
A group of pirates that sailed the seas. Among its members are:
Gutt is a Gigantopithecus who is a self-styled master and cruel and ruthless pirate captain of the high seas. His name is based on the long sharpened fingernails that he uses to "gut" his enemies. He captures Manny, Sid, Diego, Scrat and Granny and attempts to make them part of his crew. His friendly demeanor quickly vanishes when Manny refuses; he throws the mammoth and his friends overboard and furiously vows revenge when they destroy his ship during their escape due to being failure intolerant. After battling Manny, Gutt lands in a cave river and grabs a piece of ice to float on the water; he notices fins sticking out of the water and is shortly after eaten alive offscreen by a siren posing as a female Gigantopithecus. However, he makes an appearance as a boss in the 2014 Ice Age Adventures video game, which is set after the events of the fourth film.
Jeremy Renner was originally set to voice the character, but was replaced by Peter Dinklage due scheduling conflicts involving The Bourne Legacy. Captain Gutt was initially written as a bear, but designer Peter de Sève had a hard time designing an ursine villain and thus instead designed him as a more versatile primate.. He is additionally modeled after the legendary pirate Blackbeard.
Flynn is a large English elephant seal (appearing to be just as big as or even bigger than Manny in the film) who makes his first appearance in the second part of Scrat's Continental Crack-up. He provides the muscle of the crew. His lack of intelligence is the source of comic relief throughout the film. Flynn likes to eat fruit, and calls the song titled "Master of the Seas" a sea shanty. When the pirates first encounter Manny's herd, Flynn inadvertently gives them directions to return to the continent, much to Gutt's exasperation.
The seal then joined the attack on the herd, squashing Sid underneath his bulk. When Manny's herd destroys the ship, leaving the pirates to drift at sea, Flynn initially panics at the prospect of drowning, but is reminded by an annoyed Gutt that he is able to swim. Flynn worries about Shira when Gutt leaves her for dead, but he later propels the pirates to land aboard a small raft made of ice.
In the final battle, Flynn and Gupta corner Sid and Granny, only for the latter to summon Precious, sending the pirates running in fear. Flynn rejoins the battle against Manny, but is defeated when Precious blasts him with water.
Raz is an Australian Procoptodon who serves as the crew's resident weapons and artillery expert, hiding an arsenal of deadly bone swords in her pouch and using her powerful legs to launch projectiles at enemies by kicking them. In the final melee against Manny's herd, she battles Manny herself, until she is blasted away by Precious.
Silas is a petrel/blue-footed booby hybrid who usually scouts out for trouble ahead of the pirates. Silas informs Captain Gutt of Manny and his herd's presence, claiming that their raft was a huge bounty ripe for the taking. Silas later attacks Manny personally while the mammoth is escaping the hyrax island, but Manny bats him away with Sid by holding him onto his trunk. In the final battle, Silas launches Gupta at Manny's face to distract him.
Squint is a Palaeolagus. He makes his first appearance in the second part of Scrat's Continental Crack-up. He is overconfident, somewhat psychotic, and dislikes being called adorable; he is berated many times by Gutt and Shira for trying to assume authority over the crew. Squint holds a rivalry with Shira, which reaches its climax when Squint becomes Gutt's new first mate after Gutt insults Shira for failing to kill Manny, Sid, Diego and Granny. In the final battle, Squint attempts to attack Shira as she is trying to free Ellie, but Shira mocks Squint's 'adorable nose', which agitates him and allows Ellie to stomp on him.
Squint later resurfaces in Ice Age: The Great Egg-Scapade where he wants revenge on the Herd for what happened to Captain Gutt, but he gets defeated by Sid and then he falls in a Crash and Eddie's trap for April's Fools.
Dobson is a Metridiochoerus, who speaks in growls, oinks, and other pig noises, although he appeared to be singing along with the crew in the "Master of the Seas" musical sequence. He teams up with Raz in firing the cannons, loading them with chunks of ice for Raz to fire with her powerful kangaroo legs, and leaps down onto the heroes's ship with her to corner Manny. Dobson later takes part in the final battle, fighting Crash and Eddie "rodeo-style", and is able to charge into Manny and knock him into the other ship along with Shira. However, Dobson was blasted away by Precious along with the rest of the pirate crew.
Gupta is a Bengali badger whose fur pattern on his back resembles a skull and crossbones, allowing the crew to use him as their pirate flag. He is shown to be somewhat cowardly, wishing to fly the white colors of his underbelly when the pirate ship was being destroyed. In the climax of the film, Gupta and Flynn corner Sid and Granny, but are scared off by Granny's pet whale Precious. Gupta is later dropped onto Manny's face by Silas, distracting the mammoth long enough for Dobson to attack him and to corner the herd. However, Gupta and the rest of the crew are blasted away by Precious.
