Storm Creatures are the foot soldiers of the Storm King in My Little Pony The Movie and associated material; they are occupationally referred to as Storm Guards in the film and some merchandise and as Storm Minions, Storm Minion Commanders, Storm Minion Boltcasters, and Storm Minion Spellshields in The Official Movie Sourcebook. They have bulky physiques, hunched backs, gray coats, white hair, and black mask-like faces. The Storm Guards serve as the Storm King's army, invading Canterlot alongside Tempest Shadow and Grubber and taking the ponies prisoner. Two of them serve as Tempest's bodyguards, distinguishable from the other Storm Creatures by the purple streaks in their hair.
They mostly speak in unintelligible growls and grunts, but in the My Little Pony: The Movie Prequel comic, some—including Ralph and Sam—have comprehensible speech. A Storm Guard appears on the A cover of My Little Pony: Nightmare Knights Issue #3, and others appear on page 1 of Issue #4. A Storm Guard also appears on My Little Pony: Friendship is Magic Issue #96 page 4. Gameloft's mobile game features several Storm Guards, including "Storm King's Guard", "Tempest's Guard", and an original character called "Klavis", a character who was scrapped from the film. In The Great Princess Caper, several Storm Creatures employ glider wings for aerial combat; this concept was also recycled from early drafts of the film. They also appear in the chapter book The Stormy Road to Canterlot and are mentioned in Beyond Equestria: Fluttershy Balances the Scales. In What Lies Beneath they appear as illusions, manifesting Silverstream's deepest fears.
In Enterplay's trading cards, the Storm Guards are identified as hedgehogs, like Grubber, but they differ from earlier-introduced hedgehogs in size and sapience.
