Kill the Mad Scientist (マッドサイエンティストを斬る, Maddo Saientisuto o Kiru) is the eleventh episode of the Akame ga Kill! anime.
Team Stylish carries out their attack on the Night Raid base. Multiple foot soldiers die during the assault. A member named Trooma incapacitates Leone. One of the members named Toby duels Akame. Akame is unable to poison him fatally with her Imperial Arm known as Murasame because his body is mostly machine due to it being installed with multiple weapons. She is eventually able to kill him after he is impaled by Lubbock in an ambush. Meanwhile, Tatsumi fights Kaku. Kaku is another member of Team Stylish. He is shocked to find that he has possession of Sheele's old Imperial Arm known as Extase. The battle is interrupted by Mine. She is also horrified to see Extase. Mine quickly kills Kaku. She safely retrieves Extase. Trooma prepares to ambush Mine. Trooma is attacked by Leone who had recovered. Leone accidentally kills him with a single blow. This displeases her. After Night Raid regroups, everyone but Tatsumi collapses. Tatsumi has been afflicted with a paralytic poison during the battle. When more foot soldiers move in, a biological Imperial Arm user named Susanoo intervenes and dispatches them. Outmatched, Dr. Stylish injects himself with a liquid that turns him into a Danger Beast, and he consumes his remaining men. Tatsumi, Akame, and Susanoo fight Dr. Stylish before he is shot by Mine. Akame slashes Dr. Stylish's real body contained in the Danger Beast. Akame kills Dr. Stylish. Najenda and a girl observe the aftermath of the battle.
