Starkiller, born Galen Marek and also known as The Apprentice, is the Dark Jedi anti-hero protagonist of the Star Wars: The Force Unleashed project. The character's likeness and voice are provided by Samuel Witwer. Raised by Darth Vader, he is made the secret apprentice under the name "Starkiller" due to being potent with using the Force for destructive purposes and described as less of an assassin and more of a "Force wrecking ball". The character's name is taken from Luke Skywalker's original name "Annikin Starkiller".
IGN called Starkiller's story "nice and complete". Game Informer, UGO Networks and GameDaily also gave good reviews. However, GamesRadar has criticized Starkiller's design. In GameSpot's vote for the greatest video game character of all time, Starkiller (as "The Apprentice") was eliminated in round 1 against Niko Bellic.
