The male Berserker class in For Honor was voiced by Stefán Karl Stefánsson, an Icelandic actor best known for portraying the villain Robbie Rotten in the live-action children's series LazyTown. The character was the subject of various internet memes throughout the show's run, the most popular of which being the song "We Are Number One" from the episode "Robbie's Dream Team". Following Stefánsson's widely-publicized death from bile duct cancer, a pair of Robbie Rotten references were added to the game as a tribute. These include:

• An emote named "Number One", where the Berserker transforms into a statue raising a finger upwards, resembling a pose Robbie Rotten does leading into "We Are Number One", with the caption "In Memoriam - to our Number One villain".
• A bot named "RobbieBotten" who plays as the Berserker and wears blue and red stripes, a similar but not exact proximity to the color scheme of Rotten's outfit.
