The Underworld Army is a huge army from the underworld, consisting of a massive legion of demonic monsters born from the depths of the Underworld and an antagonistic faction in the Kid Icarus videogame series. In the original game, it was led to believe that Medusa was the leader of the Underworld Army, However, in Uprising, it revealed that Hades is the true leader. They are the main antagonist group in the Kid Icarus Series and one of the main factions in Kid Icarus: Uprising. This army consists of about 121 members.
The Underworld Army is composed of the most well known enemies in the Kid Icarus series, such as the Eggplant Wizard, Plutons, Komaytos, and other enemies in Kid Icarus and Of Myths and Monsters. It also has many commanders such as Twinbellows, Thanatos, and Hewdraw.

Normally When Pit encounters the Clubberskulls, they resemble skulls with horns, wrapped in chains. If Pit breaks the chains, the skull open up revealing their true form; a grotesque heart with one eye and arms. The skulls actually form the hands on the creatures' arms. The Clubberskull makes an appearance as one of the enemies in the videogame Super Smash Bros 4 for the 3DS in the mode; Smash Run. Much like the ones in Kid Icarus: Uprising, Clubberskulls appear in a demonic skull wrapped in chains, but should any character attack the Clubberskull, it reveals it's true form and attacks them. It is one of the toughest enemies in Smash Run, as it can deal a huge amount of damage, and it has huge defenses.
