The Boys Season 5 is just 24 hours away, and the marketing campaign for the series is in full swing as the cast and crew are giving interviews to promote the series. One of the many cast members whose interviews have been illuminating about the upcoming season is Karl Urban, who plays Billy Butcher in the Prime Video superhero satire.One such interview was between Karl Urban and ScreenRant's Liam Crowley. Crowley asked Urban if the latter had found his experience of shooting The Boys Season 5 freeing. Urban responded positively, saying:"Yes, actually it was really refreshing to get to season five and discover new territory to mine. And that was at the end of season four, Butcher gives over to this powered symbiote that is festering within him. That meant for me, I had to really figure out who Butcher was now going into season five. And I really approached it like he was a dual character, like a character with a split personality."Karl Urban's Billy Butcher's dark turn in The Boys Season 5 explained: View this post on Instagram Instagram PostThe fourth season ended with Homelander delivering a crushing victory over the good guys. Butcher sees Ryan kill Grace Mallory, and this event causes him to cede control of his body to his darker half, represented by Jeffrey Dean Morgan's Joe Kessler. Kessler is a physical manifestation of Butcher's hate for the supes and his mutated cancer that bursts out of his body.Every time Butcher uses his powers, he is not himself, but rather Kessler. This is why Karl Urban described Billy Butcher and Joe Kessler as separate personalities in the ScreenRant interview promoting The Boys Season 5. He explained:"When he would flick the switch and he would utilize that power, he became very robotic, very Terminator-like. No compassion, just a cold, ruthless killer, a monster. And then to counterbalance that in the times where he wasn't that, you still have the Butcher of old. He is still mercurial and fun to be around. The relentlessly driven leader of The Boys, getting everybody to point in the right direction, but also a character who is struggling to hold onto the vestiges of his humanity. And so that was a fun challenge to incorporate new aspects at the end of this journey."Based on this quote, it seems that we will see the push and pull between two of Butcher's sides throughout the eight episodes of The Boys Season 5. Karl Urban did tease something similar in the MovieWeb interview last week:"I think what excited me most was, first of all, the fact that Butcher is essentially so desperate that he's turned himself into the monster in order to defeat the monster. That was wonderful because it opened up a whole new, fresh territory for me to play as an actor. As you know, when he goes into that mode, when he flicks that switch, it's very cold, very Terminator-like, and then the other side of that coin was, you know, sort of really trying to discover or hold onto what shreds of humanity that he had left. And so that was a real joy in Season 5 to get new fresh territory to mine."Will Billy Butcher meet his maker in The Boys Season 5?The season 3 finale reveals that the doctors have diagnosed Butcher with cancer because of the Temp V he used throughout the third season. To cure himself, Butcher injected himself with Compound V, which gives someone their superpowers permanently between seasons 3 and the season 4 premiere. The Compound V basically mutated Butcher's cancer.Therefore, Butcher's death was marked all the way back in the season 3 finale. It's no longer a question of "If Butcher dies", but rather "when he dies"."In the fifth and final season, it’s Homelander’s world, completely subject to his erratic, egomaniacal whims. Hughie, Mother’s Milk, and Frenchie are imprisoned in a “Freedom Camp.” Annie struggles to mount a resistance against the overwhelming Supe force. Kimiko is nowhere to be found. But when Butcher reappears, ready and willing to use a virus that will wipe all Supes off the map, he sets in motion a chain of events that will forever change the world and everyone in it. It’s the climax, people. Big stuff’s gonna happen."The Boys Season 5 will stream tomorrow on Prime Video.
