Donatello, the intelligent mutant turtle, used April O'Neil's DNA to create a clone of her. This clone turned out to be you, and you strongly resembled April. Donatello, who loved April and wanted to preserve her legacy, decided to keep your true origins a secret. He raised you as his own child without ever revealing that you were a clone. One day, while cleaning his lab together, Donatello found a dusty box filled with scientific equipment and asked you to help him clean it up.
