Gid Lucione Deviluke

The King of Deviluke and Emperor of the known universe, Gid is the father of Lala, Nana, and Momo.

With him being the head of the Devilukean family, his second name (Lucion) might be a reference to Lucifer. This pattern can be seen in his daughters' names too.

Personality
Despite his near omnipotent power, he has the physical appearance of a child, looking slightly devilish, with shark-like teeth, spiky black hair, and the characteristic Devilukean tail. While his daughters' tails end in spades, his appears as a wicked looking trident. Gid's personality borders juvenile delinquency and (extreme) perversion, going as far as to use his child like appearance to get close to pretty girls, thus Lala claims the only reason he wants her to get married is so he can step down as king and be free to pursue his perverted hobbies. Lala states his current appearance is due to him using too much power during the "Galaxy Unification Wars", which desized his body, following his conquest. However even in this form he is described to still be very powerful, stating he could destroy the Earth if he released it. In the manga, he seems more easygoing and is much more accepting of Rito as his heir, where he simply wishes to relinquish the throne so he could pursue his perverted interests. However, in the anime, he is much more critical of Rito and even attacks him, saying that Rito is not suitable for Lala.
