Ice Age: Continental Drift
She makes her first appearance in Ice Age: Continental Drift, when the pirates found the Herd on their "ship", Shira caught Diego's eye.

After finding land Shira escapes from the Herd but Diego managed to pinned her. Shira is seen locked up in a giant tree. Later that night Shira is approached by Diego whom brought water for her at first she refused it but changes her mind after Diego tells her to die of thirst. Shira questions Diego about being soft for a saber, than sees why he wasn't in a pack but Diego responds that he choose to leave his pack and Shira tells him that she too left her pack as well. Diego tells her that she simply traded one pack for another, and that his herd always has each other's backs, pointing out that Gutt hadn't made any thoughts of planning a search party for her in the first place. After escaping from her prison Shira returns to her crew and tries to inform Gutt of the Herd, Shira finally realises that Diego is right about Gutt not having any loyalty for her. After pinning Diego, he convinced her to be with him and join the Herd. Shira notices Gutt is right behind them; she push some ice to make sure Gutt dosen't make it to the Herd's new ship, Shira is left behind and stares at Diego, showing she is in love with him.

As the Herd is sailing home, Diego can not stop thinking about Shira and her safety and realising he too has fallen in love with her. Shira is seen fighting against her former crew and trying to save Ellie. When Gutt and his pirate crew are defeated; Shira asked Diego if she's still in his scurvy crew; Diego welcomes her and both Sabers stared at each other romantically and now are lovers

Ice Age: The Hidden Treasure
Shira's makes a small appearance nearly the end of the issue, as she is seen with the other members of the Herd shouting "surprise" to the opossom brothers and celebrating their birthday. Shira is seen next to Diego meaning that she and Diego are a couple.

Future
Shira marries Diego and might or might not have cubs with him. She will be the new leader of the pirates since Gutt has been mistreating Flynn.

Personality
At first, Shira appeared to be cold and gruff and she showed loyalty to those who helped her. Shira also shows a little immature behavior towards Diego calling him names but she also shows to be clever, smart, and not to be swayed by lies.

After being caught by Diego for trying to escape and putting her in "jail" Shira's face shows a little sadness and loneliness but changes quickly to her aggressive and being sarcastically towards Diego.

Later on she shows that she is very kind, brave and caring especially towards Diego. She left her whole pack mentality and decided to leave and she felt like she didn't felt like she belonged there. She got into Gutt's group and Gutt embraced her as First Mate.
