Tikal (ティカル Tikaru?) is a fictional character from the Sonic the Hedgehog series. She is a 4,000 year old anthropomorphic echidnaspirit and a former member of the Knuckles Clan who resided in theMystic Ruins. She is also the daughter of Chief Pachacamac.
In her youth, Tikal 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 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.
