The Hightail Felidae

Remember Gravija's? It's been good. Recently, Gravija challenged the Dark Lord to a duel. Each party was allowed to bring along a Guardian Spirit. Gravija brought along his, and then they both got on with the battle.

Nicknamed Hightail, Gravija's Guardian Spirit is of attribute Wind, and is also known as the fastest creature on land - the cheetah. And Hightail isn't just any other cheetah, he is from the prime breed - the king cheetahs.

I'll let you guys guess who Hightail is.
