Tikal the Echidna is an orange echidna and Knuckles' ancestor. She is often paired up with Knuckles, Sonic, Tails, Chaos and Amy. Her role in porn comics is often the one of a sex tutor, as she is very skilled in sex. She is often portraid as bisexual and loves sex with other girls.
She has a strong bond with the water monster Chaos, which can lead to pics similar to tentacle rape, though Tikal enjoys every second of it.
