Corrine

Corrine (Korrin) is a summon spirit who looks like a fox. Unlike other summon spirits, he is man-made and doesn't possess the power to control a element. By summoning him, he appear above an enemy, fall and hit those by executing a clout. Corrine has only formed a pact with Sheena Fujibayashi in the game Tales of Symphonia.

In the game Tales of Symphonia, during a lightning attack from Volt aimed on Sheena Fujibayashi in the temple of lightning, Corrine sacrifice himself by holding off the attack in order to rescue her.

Spoilers end here.

Historical Background
Corrine is based on the Japanese folklore about foxes. According to them, foxes are very intelligent animals with magical powers. Some of them have nine tails, like the ones from Verius. They're also described as spirits. Another point is that then more tails a fox have, the mere wisely a fox is. In the case of Corrine, he has only 3 tails at the beginning, but later as Verius, he has nine tails.

Trivia

 * In the anime Digimon Tamers, there is a pair similar to Sheena Fujibayashi and Corrine: Renamon represents the fox, and Rika Nonaka represents a girl with a similar haircut like Sheena's. They're both partners, and like the examples from the foxes in the Japanese folklores, Renamon can evolve to a fox-o'-nine-tails called Kyubimon (which is a simile to Verius, Corrine's second form)
