Lacospo

Lacospo is the prince of Gama Planet, though no detailed physical information such as height or weight is provided.

He is always accompanied by his favorite pet, the gigantic Iragama toad, Gamaton.

Lacospo is extremely possessive and has a deeply childish nature.

He refers to himself as "Bokutan" and calls Lala "Lalatan," emphasizing his immature and self-obsessed character.

He easily becomes jealous and resorts to sneaky, underhanded methods to get his way.

He hails from Gama Planet and carries the title of prince.

Lacospo’s primary goal is to marry Lala Satalin Deviluke, despite her clear and steadfast dislike towards him.

His infatuation with Lala rivals that of Gid Lucione Deviluke’s, though Lala finds his advances especially detestable.

Lacospo’s main asset is Gamaton, his colossal pet Iragama toad.

Gamaton can secrete a unique mucus that dissolves only the fiber of clothing, making it a highly sought-after substance in the galaxy’s black market.

Using this ability, Gamaton can spit out this solution, which can then be manufactured into gas or bombs, and, when compounded, can act as a sort of medicine.

Gamaton’s natural predator is a magical beast called Jiro Snake.

Lacospo is fixated on Lala Satalin Deviluke, constantly attempting to win her hand in marriage through any means necessary.

He holds a pet-like attachment to Gamaton, even giving him a cute nickname and keeping him always at his side.

He has hired various assassins, such as Golden Darkness and Ranjura, to eliminate his perceived rivals, especially Rito Yuki, whom he sees as his main obstacle to Lala’s affection.

He antagonizes several other characters, including Haruna Sairenji and Oshizu, when trying to capture Lala.

Lacospo’s usage of third-person nicknames for himself and others (like “Bokutan” and “Lalatan”) highlights just how immature and self-centered he truly is.

Gamaton's croak changes between appearances: in his first scene, he says "Nyaa," but later it becomes "Geko."

Gamaton's secretions are a hot item in the galactic black market, used for a variety of mischievous purposes.

Originally, Ranjura was planned to be a different character from another series, but was designed uniquely for Lacospo's storyline.

"I, Bokutan, will definitely make Lalatan mine!"

“Gamaton, let’s show them the power of Iragama!”

First Assassination Attempt

Lacospo initially tries to kill Rito Yuki by hiring Golden Darkness as an assassin.

His plot is foiled by Lala, and in the chaos, Lacospo is easily defeated and literally sent flying along with Gamaton.

Return and Second Attack

Refusing to give up, Lacospo next hires Ranjura, an assassin capable of producing webs from his own body.

Ranjura briefly manages to trap Rito and Golden Darkness, but is soon outsmarted by Golden Darkness and devoured by one of Momo Belia Deviluke’s man-eating plants.

Lacospo escalates further by using Gamaton's abilities to capture Haruna Sairenji and Oshizu, threatening them as hostages to force Lala into marriage.

However, he is defeated once again, thanks to the teamwork of Golden Darkness, Nana Astar Deviluke, and Momo Belia Deviluke.

Despite several grand schemes, Lacospo remains a comedic and persistent side character, always ending up on the losing side of his own outrageous plans.

His blend of arrogance and childish mannerisms makes him a memorable, if often ridiculed, recurring antagonist in the series.
