Tikal the Echidna (ティカル・ザ・エキドゥナ Tikaru za Ekiduna?) is a fictional anthropomorphic echidna from the Sonic the Hedgehog series. She is a spirit from 4,000 years ago and the daughter of Chief Pachacamac. She was once a member of the Knuckles Clan who resided in Mystic Ruins. In her youth, Tikal lived in a period of war where she opposed her father's power-hungry ways of invading other countries. During this time, Tikal 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 from the Master Emerald when Dr. Eggman planned to use Chaos to take over the world, where she aided Sonic the Hedgehog and his allies by showing them visions of her past in an effort to stop Chaos from destroying the planet. After Chaos had been calmed by Sonic, Tikal left with Chaos to live their lives in peace.
