Tikal is a 14 year-old Echidna. but then she died
but she's inside the master emerald with chaos
No, your answer is incorrect my friend. Tikal is 14, but she did not die, after her Father and his warriors knocked out her and killed the baby chaos to get to the master emerald, it angered the beastly aquatic monster "Chaos" and he used all the emeralds and turned into his most powerful form "Perfect Chaos" and killed Tikal's father and his warriors. Tikal remembered what her grandmother had said about the seven chaos emeralds and quickly raced up to the emeralds to put a stop to all the destruction. The master emerald itself took both Tikal and Chaos and sealed them both in itself. Watch: http://www.youtube.com/watch?v=iOeY908Sk_0&feature=related
