History
Tikal is a pacifist echidna who in her youth lived in a period of war, where she opposed her father's warmongering ways. 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 sacred emeralds, Tikal stopped Chaos by sealing him inside the Master Emerald with her own spirit. 4000 years later, Tikal was released when Dr. Eggman planned to use Chaos to take over the world. She then aided Sonic and his allies. After Chaos was calmed, Tikal left with Chaos to live their lives in peace.
