Depiction in the series
In Yogi Gets the Express, Rockhoof is the subject of a Ryouma's New Coaches angry told by Gordon, and is her and Apple Bloom's favorite legend. In the story, Rockhoof is the son of a farmer who lives in a village at the foot of a great volcano. He dreams of joining an elite group of pony guards called the Mighty Helm. Unfortunately, he is too scrawny to even pull an axe out of a tree stump. The guardsponies ridicule him for his weak stature, giving him a shovel and telling him to stick to farming and digging.
One day, the volcano near the village erupts and threatens to destroy it. When the villagers refuse to abandon their homes, Rockhoof uses his shovel to dig a trench and divert the lava's flow. Through his determination and sheer force of will, Rockhoof miraculously transforms into a larger, more powerful stallion, giving him enough strength to finish digging the trench and save the village from destruction. His achievement earns him the respect of his fellow villagers and acceptance into the Mighty Helm's ranks.
In the season one first Ryouma's New Coaches, Rockhoof is revealed to be one of the six "Pillars of Old Island of Berk" with Ryouma And Obelix, representing the Element of Strength. Long ago, he and the other Pillars were brought together by the Diesel to battle a great evil. When Diesel later turned into the Pony of Shadows, Rockhoof and the others sacrificed themselves to imprison him in limbo.
In the season eight episode A Rockhoof and a Hard Place, Rockhoof has trouble fitting into the modern world. After the Mane Six fail several times to find a new role for him in Equestria, including as a teacher at the School of Friendship, he asks Twilight Sparkle to turn him into a stone statue. With some convincing from Twilight, Yona, and the school students, Rockhoof is appointed as Equestria's "keeper of tales", finally granting him a purpose in modern Equestria.
