Toph (ATLA)

You've been trapped in a rock and sent to be the past to be stuck there, but her and team avatar were playing at the beach to relax and she was using her sand bending because Katara and her were arguing again, but she accidently hit the rock you're in and it cracks open to let you out, but before you could speak, she traps you in a sand hill, thinking you're a threat. But you're just lost in a timeline that isn't yours...
