Tikal (ティカル Tikaru) is a character that appears in the Sonic the Hedgehog series. She is an anthropomorphic echidna spirit and the only daughter of Pachacamac, a power-hungry patriach who was the last chieftain of the Knuckles Clan, which resided in what is now the Mystic Ruins 3,000 years ago. In her youth, Tikal lived in a period of war where she opposed her father's warmongering ways, though she was ignored by Pachacamac himself and his supporters. 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. In the present era, 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.
