"My brain can calculate any move you might make."
The leader of the prison island of Cyber City, Giga is the leader of the most powerful district of the Maruhage Empire, and Tsuru Tsurulina IV's right hand man (though this could be seen as blackmailing). In appearance, Giga is a large muscular man with spiked purple hair. His armor is very abstract, with strange patterns on some parts, and green rings hanging around his arms. Giga's personality is not a pleasant one. He is extremely cruel to the inhabitants of Cyber City, he disturbingly enjoys toying with his opponents, and the only thing he seems to care about is his ever-growing art collection, which consists of the fist masters that he turned into abstract sculptures!
Giga is not alone in ruling Cyber City. He has six powerful henchmen called the "Six Electric Brain Warriors" (Six Cyber Knights in the dub) who help him keep the cities inhabitants in line and defeat any intruders. He also has two women who are obsessed with him and cling to him constantly. While the Electric Brain Warriors deal with problems below, Giga prefers to stay in his tower and oversee things.
His main ability is the power of "Obuje Shinken" (Fist of Objets オブジェ真拳, dub: "Fist of Objet D' Art"), which allows for the creation of pieces of art that he uses to attack. This ability also allows him to transform enemies, particularly those with "Shinken" abilities, into art both for his collection and to assist him in powering up upon breaking them. He first showed this ability on a unnamed man who fights with Carrot Shinken (Fist of Carrot, dub fist of the carrot), who battled off-screen with Giga who appeared to have been easily beaten. He is so strong that for the first part of the fight, he has Bo-bobo cornered and he didn't use any Super Fist techniques.
After absorbing many of his creations, he is able to transform into "Super Giga", which has more powerful armor and much longer pigtailed hair. His attacks have increased ten-fold, and he can now create a dimension where he is completely in charge of everything; from his enemies attacks to his own tangibility! The only way to attack Giga now is through either powers even greater than his own, or through other art forms! However, weaker art attacks will not work on him, and he has the power to rate them in price!
According to his subordinates, Giga's second form is completely unknown to them, hinting towards how great his immense power truly is!
Intrusion of Cyber City
Giga is made Bo-bobo's personal enemy after Wan Ronga, one of The Electric Brain Warriors, kidnap Heppokomaru as part of Giga's hunting of the "Fist Masters." Once Bo-bobo arrives and sees how terribly Giga treats the citizens, he decides to take down Giga personally. This vow only becomes stronger after Giga, out of cruelty and his obsession with his artwork, decides to turn Heppokomaru into one of his abstract sculptures! This only provokes Bo-bobo's wrath even more, and Bo-bobo vows to finish him off, after he goes through Giga's subordinates.
The fight with Giga starts after J's defeat. Giga drops an empty coffin (the coffin acts as an elevator) down to J's level so that the rebels can challenge him on the top floor of the tower. Once up there, Giga ambushes them with a huge string of knives! At first nothing they do works on Giga, until Bo-bobo crashes through the building in a dinosaur costume and smashes Giga! He then demands that Giga let Heppokomaru go, only to see Giga's entire collection which expands across the entire room! Giga tries to squash Bo-bobo, Don Patch, and Tokoro Tennosuke in every way he can think of, but he is countered by Bo-bobo at all turns!
Giga finally gains the advantage again with his "Ultimate King" ability, where he can predict his enemies movements! He is successful at first, the rebels fail to hit him and wind up hitting each other! Luckily for them,Dengakuman secretly latches onto his arm and messes up his counterattack! The abstract master then decides to turn the rebels into statues, but even this blows up in his face, as Bo-bobo turns back to normal and smashes him with noodles! He gains another advantage when he activates his evil stereos, which paralyze his enemies in place with the music that leaks out! It works, but Giga takes too much time to gloat, and gets smashed in the face by Torpedo Girl! After she destroys his stereos, she and the hajikelist trio attack Giga all at once.
Giga still refuses to give up. He creates a massive staircase, with himself at the top and the rebels at the bottom. Despite the large number of traps, Bo-bobo and the rebels ride a walking elevator to the top, and Bo-bobo pile drives Giga's head into the floor! Giga is finally knocked unconscious... or so it would seem...
Fighting Bo-bobo Round 2
With Giga out cold, the rebels are free to search for Heppokomaru, until they notice that some of the statues are crumbling to pieces and fusing with Giga's unconscious body. Giga then gets up, completely transformed into "Super Giga"! He takes the fight to the roof of the tower, and activates his special dimension, making all of the rebels attacks useless! Though dominate at first, Beauty finds a weakness in Giga's technique; another form of art may be able to hurt him. Bo-bobo takes her advice and activates "Family Portrait", where he, Don Patch, Tennosuke, Torpedo Girl, and even Dengakuman take a shot at Giga. After the onslaught, Bo-bobo criticizes Giga for only treasuring abstract art whist ignoring heart-felt art. Bo-bobo then draws power by breaking his "Nosehair Soul" seal, unleashing several large dragons, which then blast him and drastically increases the afro-warrior's strength! With this new power, Bo-bobo easily harms Giga with powerful punches (but it costs him his limbs every time he uses them). Despite his determination to win, Giga is clearly outclassed by Bo-bobo, who then launches himself into the air and brings the sun crashing down on Giga's head (before he punches through it, into Giga), defeating him once and for all!
The New Emperor Playoffs
Life doesn't get any easier for Giga after his defeat. He becomes a participant in the new emperor playoffs and tries to ambush Bo-bobo with the help of Shibito, Halekulani, Haou, and Lambada, but winds up getting punched in the face by his former subordinate, Despair-Kun! He is later crushed off-screen by Crimson. He somehow recovers and makes his way to the New Emperor Playoff's finals, only to get beaten by Crimson again, and then used as a sacrifice! He regains his power and original form after Bo-bobo destroys the Yamiking. Giga then returns to Cyber City and continues to rule over it (though probably not as horribly cruel as before).
Shinsetsu Bobobo-bo Bo-bobo
In Shinsetsu Bobobo-bo Bo-bobo, Cyber City gets invaded by the IXEX. Most of Giga's henchmen fall victim to the invading forces, but Giga manages to restrain most of them. However he misses hajikelist Hiragi and gets beaten by him with a clothes pin hajike attack. Later on, he is dragged to a prison of the Neo Maruhage Empire, where he is to be punished for his failures towards the empire. He revolts with Gunkan, Suzu, and Dengakuman, but they are all beaten by IXEX member, GURA-san the Punisher. He is also seen in the last chapter of Shinsetsu, where he attends Tennosuke's Hair Hunter Reunion.
