A Crystal Pony who befriended Sombra when they were foals.

Depiction in the Comics
Radiant Hope is first introduced in FIENDship is Magic Issue 1. She was an orphan who was equally teased as filly along with Sombra, and the two become close friends.

Throughout that year, Sombra and Radiant Hope save up gems for the upcoming Crystal Faire, a magical celebration centered around the Crystal Heart. When they go to gaze upon the Crystal Heart at the palace, they have visions of the future—Hope sees herself as a princess.

When the Crystal Faire arrives, Sombra suddenly comes down with severe aches and pains, which only worsen as the Faire goes on. Radiant Hope forgets about the Faire and stays at Sombra's bedside, and by the next day Sombra is healthy again. Each following year, Sombra suffers the same pains on the day of the Faire and worsens to a point where his body begins to crystallize and fracture. She desperately uses her magic to heal Sombra, and she gains her cutie mark, discovering a special talent in healing any injury or ailment.

Hope's magical talent gets the attention of Princess Celestia and Princess Luna, and she is invited to study with them in Canterlot.

She return to the Empire to only to find Sombra as a darker version of himself and a crystalized Princess Amore. She refuses Sombra's offer to join and shatters the statue much to her horror.

She informs the Princesses of what Sombra has done and she witnesses her home vanish after her former friend's defeat.

In Issue #34 she is revealed to be alive and brought together previous foes of the Mane 6's foes to distract them while resurrections Sombra himself.
