Developer The Coalition tapped three accomplished video game and television actors to portray Gears of War 4's main characters. Kait is portrayed by Laura Bailey, who provided the voice of Kid Trunks in Dragon Ball Z, Fiona in Tales from the Borderlands, Spartan Olympia Vale in Halo 5: Guardians and numerous other roles. Del is voiced by Eugene Byrd, who plays Marcus "Boomer" Boone in Battlefield Hardline and has recurring roles on the TV shows Bones and Arrow. JD gets his voice from Liam McIntyre, who also plays the lead in Starz's Spartacus series and had a run on The Flash as Weather Wizard.

They all appear fairly pumped to have roles in Gears of War 4.
