Tikal (ティカル, Tikaru?) was designed by Yuji Uekawa to be a light orange, female, anthropomorphic echidna. She first appeared in the game Sonic Adventure, cameoed in later games, and played similar roles in other mediums of the series. She is 14 years old, 95 cm (3 ft 1 in) tall, and her weight is unknown. Tikal's Japanese voice-overs are done by Kaori Asoh, while Elara Distler and Bella Hudson do her voice in the English language version.
Tikal is the daughter of Chief Pachacamac and is said to have originated from the same tribe as main character Knuckles the Echidna. Her mother had died when she was young, so she depended on her grandmother to raise her. Tikal respected her and believed everything she taught, resulting in her becoming a pacifist. After her grandmother died, Tikal always cherished her words and followed her wishes to oppose Pachacamac's power-hungry ways in invading other countries.
Sometime during her life she found the altar of the Master Emerald and Chaos Emeralds near the Echidna city, and there she met and befriended the peaceful creatures known as Chao. Unlike the other Echidnas she could come close to the altar despite a mysterious barrier protecting it. During one visit to the altar, she was introduced to Chaos, the guardian of the Chao, who let her stay around the altar due to her friendliness to the Chao. As time passed, Pachacamac and a group of his men stormed the altar to obtain and use the Master Emerald and Chaos Emeralds for total power. After knocking Tikal and some Chao away, Chaos became angered, causing him to kill Pachacamac and his men. Running to the Master Emerald, she remembered the ancient poem about Chaos. Now realizing what it meant, she recited it. The Master Emerald then responded by sealing Chaos and Tikal's spirit in itself.
Several thousand years passed, and Dr. Eggman read the story about Chaos on an ancient stone tablet. In order to recruit Chaos' help in his quest to rule the world, Eggman shattered the Master Emerald, awakening Chaos and Tikal's spirit. Subsequently, Tikal transported Sonic and his friends (most notably Knuckles) to the past to know the trouble that befell her world before. Despite this, Chaos managed to obtain the Chaos Emeralds and used their negative energies to become Perfect Chaos. As he began destroying Station Square, Tikal appeared and told Sonic that Chaos had to be sealed in the Master Emerald once again. However, Sonic disagreed, as Chaos would still be angered, and history would likely repeat itself once again. Instead, he used the positive energy of the Chaos Emeralds to become Super Sonic, then battled and defeated Perfect Chaos. After being defeated by the positive energy of the Emeralds, Chaos was neutralized and calm. Tikal then explained to him that the Chao were alright and happy, and she and Chaos rose into the air and disappeared in a flash of light.
