Little Strongheart

Little Strongheart is a young female buffalo who appears in Over a Barrel, Pinkie Pride, and Friends Forever Issue 31. Her name is in the style of a traditional Native American name, and her feathered headband is also part of the Native American motif shared among the buffalo herd.

Depiction in the series
Little Strongheart is first seen assisting her herd in hijacking a train car containing Bloomberg and Spike. Rainbow Dash attempts to confront her as she runs on top of the train, but Little Strongheart manages to avoid with somersaults and weaves past her. Eventually, Rainbow Dash gets too caught up in the chase and crashes into a railroad post.

Little Strongheart is seen again at the Buffalo village. She apologizes to Rainbow Dash for her actions during the heist, justifying the tree-napping as an attempt to reclaim her herd's stampeding grounds, which the ponies of Appleloosa have claimed as an orchard. Her explanation convinces Rainbow Dash to join the herd's cause.

Her attitude towards Braeburn in their first meeting is very conciliatory, but Applejack and Rainbow Dash start an argument, preventing any agreement. After a fight between the townsfolk and the buffalo, an agreement is finally made. The herd stampedes away, with Little Strongheart bidding her new friends goodbye.

Little Strongheart makes a brief cameo at the beginning of Pinkie Pride during the party Cheese Sandwich throws for the ponies and buffalo in Appleloosa.

IDW comics
In My Little Pony: Friends Forever Issue #31, Little Strongheart calls upon Rainbow Dash to help when the buffalo are unable to grow food during their growing season. With guidance from Chief Thunderhooves, Rainbow Dash and Little Strongheart go on a journey to find the Rainbow Crow and bring warm weather to the buffalo's valley. Along the way, Rainbow Dash learns to accept Strongheart's traditions and methods.

The Elements of Harmony guidebook
CHIEF THUNDERHOOVES is the wise and proud leader of the buffalo tribe that sought to reclaim Appleloosa from its pony settlers and repurpose it as a traditional stampeding ground. With the help of a young and agile buffalo named LITTLE STRONGHEART, the tribe was able to come to an agreement with the ponies, allowing them both to share the orchard.

Personality
Little Strongheart is a levelheaded buffalo, serving as the voice of reason for the more short-tempered Chief Thunderhooves. She displays more kindness and patience toward the Appleloosans than her fellow buffalo, and she is the most opposed to the feud between her tribe and the ponies.

In My Little Pony: Friends Forever Issue #31, Little Strongheart displays a deep commitment to buffalo traditions and takes offense when Rainbow Dash questions them.
