I found Tikal the Echidna!
Tikal lived in a time of war, during this time she befriended the local Chao and their guardian Chaos. When Chaos went on a destructive rampage after her father attempted to steal the Chaos Emeralds and the Master Emerald, Tikal stopped Chaos by sealing it inside the Master Emerald with her own spirit. 4,000 years later, Tikal was released when Dr. Eggman planned to use Chaos to take over the world, where she aided Sonic the Hedgehog and his allies. After Chaos was calmed, Tikal left with it to live in peace.
