Tony and Tia Castaway

Tony and Tia Castaway are the main characters in the first three Witch Mountain movies. They are humanoid extraterrestrial beings from another world that was in the process of being destroyed, and that had three suns.

Escape to Witch Mountain
Since they had no parents, they were placed in an orphanage with a Starcase as their only item. after seeing Snow White and the Seven Dwarves, Tia predicted that a car was going to hit Derinian and warned that guy not to get into the car that he was going in for the that car was going to hit that car. And after that scene, Derinian informed his employer Aristole Bolt. So Bolt had Derinian be Tony and Tia's uncle. But they escaped and hid in a winnebago owned by a traveling widower named Jason O'Day, and he agreed to take them to where they are going, Witch Mountain, when they got there they finally met their real Uncle Bene. He explained when their home planet was dying they had to come to Earth, Tony, Tia and Uncle Bene escaped in their spaceship.

Return from Witch Mountain
Now older, they came back from Witch Mountain to take a vacation in Los Angeles. Tony was discovered by Dr. Gannon and Letha and kidnapped him for their dastardly deeds, kinda like Bolt, but luckily, Tia saved him with the help of a group of would-be tough kids called the Earthquake Gang and a hapless tuant officer named Mr. Yokomoto which the Earthquake gang nicknamed Yo-Yo.

Beyond Witch Mountain
Tia and Tony follow their Uncle Bene to Earth in his attempts to find his long-lost-grandson. Bolt discovers that Tia and Tony have returned and he sends out Deranian to catch Jason O’ Day so he can lead Bolt and Deranian to Tia and Tony. Uncle Bene is telling the kids that they must go back to their planet while he searches for his grandson. His grandson was on a nature walk with his class when a bridge broke and Gregory, Uncle Bene’s grandson, moved a big log over to his class with his powers so they could grasp it and they could climb up to safety. Tia and Tony refuse to leave and Uncle Bene dies because of his old age and he lets them search for his grandson. Tia and Tony go to Jason O’ Day who agrees to help them find Gregory. When they stop to buy Tia and Tony some clothes, Jason goes back to his car and he’s kidnapped by Deranian and Bolt. They give him a drink that makes him drunk and Jason tells them where the kids are. The kids come to Bolt’s mansion to rescue Jason and they run away to a hospital where Gregory is. They tell Gregory all about himself and while they are taking him back home, Tia and Tony decide to stay and, with Jason, find all the survivors and send them back home.

Powers and Abilities
Being brother and sister, Tony and Tia are capable of communicating with each other telepathically. They each have individual abilities of their own.

Tony can telekinetically movie and control inanimate objects via music; such when he plays his harmonic which seems to make his telekinetic abilities stronger. He powers are not as strong as his sister's and are less effective.

However, Tia's special abilities appear to be much stronger and more effective than her brother's are. She can telepathically speak to and control animals, and has unclear visions about her and Tony's muddled childhood. She can also render locks useless.
