c. 32 BBY
Around 32 BBY, Shadow Four was created in a cloning tank on the water-world Kamino. He was created after his template, Jango Fett, and looked exactly like him. He was trained on Kamino by trainers, many of which could be Mandalorians. He trained for around ten years, and during the Clone Wars, he was prepared to serve under Jedi General Anakin Skywalker. He was assigned to Shadow Squadron, a unit commanded by Skywalker.While serving under General Skywalker, Shadow Four and his fellow troopers were deployed to the Kaliida Shoals Med center to prevent a giant Separatist warship, by the name of the Malevolence, from disabling the med center. He left the Venator-class ship Resolute, flagship of General Skywalker, and headed for a nebula, an obstacle in their way.
They went inside the nebula to shave off the time it would take to go around, and going through it was necessary to catch General Grievous and his crew. While in the nebula, they stumbled across a giant neebray manta breeding ground, but no pilots were killed, and one pilot only had one engine damaged, nothing serious. Once breaking out of the nebula, the Malevolence appeared out of hyperspace and started its attack. It fired its ion cannons and disabled three Pelta-class frigates and launched a dozen or so vulture droid fighters against the Republic Y-wing bombers.
The clone pilots and Jedi evaded the bombers and fired several proton torpedoes at the massive ion cannon, after it fired the cannon on them, disabling three fighters, none of which was Shadow Four. The proton torpedoes caused the colossal ion cannon to overload and blow up when it tried to fire against, achieving victory for the Republic. Shadow Squadron had half of the squadron's pilots killed or disabled.
