|Behind the Scenes|
The Friendly Group from Another Planet (惑星ペンタギンのサダ吉とその仲間達), alternatively known as the Aliens, are a group of small extraterrestrials in Power Instinct Matrimelee, Shin Gouketsuji Ichizoku: Bonnou no Kaihou, Goketsuji Ichizoku Matsuri Senzo Kuyou e CR Goketsuji Ichizoku.
The group came to Earth with the excuse of wanting to establish a friendly relationship with the humans, but the series' descriptions suggest a less pacifist mission. They hail from the planet Pendagin, and the only one of them known by name so far is Sadakichi, who makes an appearance in CR Goketsuji Ichizoku as an event character.
