Joshua Bat-Levi was a male Human born circa 2305. He was the twin brother of Darya Bat-Levi, and though only two minutes younger, referred to himself as the baby brother. His sister gave him the nickname "Jock-o". Tragically, the engine malfunctioned, and as Joshua attempted to stop an energy overload, the ship exploded, killing him and severely injuring his sister.
