The mecha genre of anime has enjoyed a long-run as a fan-favorite staple of the medium. Mecha nearly always revolves around enormous robots - typically piloted by humans - involved in both combat and adventure. Frequently blending futuristic action and technology with human drama and storytelling, many of the finest mecha anime have explored themes such as sacrifice, heroism, and the grim impact of warfare and destruction on both individuals and societies as a whole.
