The Boys season 4 introduces several new characters in its early episodes, and a surprising addition to the show has proven to be this outing’s secret MVP. Although The Boys season 4 is building up to the series’ fifth and final season, it still brings in newcomers — most notably, the Supes who join The Seven after Queen Maeve’s and Starlight’s departures.

There are additions on the other side of the conflict as well, including Frenchie’s love interest, Colin, and Butcher’s old friend, Joe Kessler. With these characters, The Boys season 4 continues to expand the show’s cast and world. Of course, some of the Amazon show’s new characters take on more prominent roles than others — and one, in particular, steals the spotlight in The Boys season 4’s opening episodes.

Although Homelander’s volatile behavior and Butcher’s worrisome antics remain entertaining, this newcomer brings something fresh to the fourth season. As things get increasingly darker, it’s crucial to have characters who add humor and unpredictability — even if they’re pretty dark themselves.
