Roberto Katze

Roberto Katze (ロベルト＝カッツェ) is a side character introduced in Shinyaku Toaru Majutsu no Index. He is the current President of the United States of America in the Toaru Majutsu no Index series.

Appearance
A large man with a muscular physique, he has swarthy-skinned due to the fact that he is Hispanic. His most prominent feature is his swept hair and accompanying his thick chin curtain beard.

Personality
Unusual for a President, Roberto shows familiarity and openness to people nearly to the point of childishness. Although, his appearance says otherwise, he shows an intelligence uniquely his own.

Along with this, Roberto has the propensity to embellish the truth for his own gain. An example of this is when he exaggerates his father's apparent many deaths.

Background
He is the third Hispanic President of the United States. His campaign was apparently backed up by Olay Blueshake, the queen of media. With his personality as well as his "verbal slips" on political matters, he is referred to a strange politician; because of this, his approval ratings do rather well from them, because the electorate feels more of a connection.

He is still single, although he has a fiance that he has already proposed marriage to.

Angel Fall Arc
In the anime series, though he didn't make a physical appearance, while in the form of Shirai Kuroko, Roberto made an appearance in a press conference due to one of his many political scandals. His only speaking line was "Yes, we can." Roberto's broadcasted appearance, as Shirai Kuroko, made Touma realize that his family, friends, and acquaintances weren't setting up a prank on him and a form of magic had made them change their outer appearance.

Hawaii Invasion Arc

 * Main article:Hawaii Invasion Arc

He debuts the third volume of Shinyaku Toaru Majutsu no Index, showing his ability with the media, regarding the aftermath of World War III. He later escapes his own security forces, aware of a strange malaise that seemingly makes previous normal people turn against America, even within the core of his government, and decides to investigate on his own. His disappearance later leads his aide, Roseline Krackhart, to find him, who is also aware of the suspicious people in government.

Meanwhile, Roberto uses the Imperial Package to track the movements of suspicious persons, and discover a threat that could take the lives of thousands of people. He is later attacked by one of the persons who have their loved ones being controlled by Saronia Irivika of GREMLIN, but is able to subdue him using his negotiating prowess. Hither, he discovers that the only thing that all the controlled people have in common are the look in their eyes, a blank and spiritless gaze. Roberto discovers that the person who attacked him is not one of those people are directly controlled, and as such is determined to use him to get behind the controller's defenses. Roberto later arrives at the Coral Street Shopping Mall, just in time to save Accelerator from GREMLIN magicians, after Accelerator accidentally used magic. He later takes Accelerator away from the chaos, where they converse about the situation regarding GREMLIN's influence in the the United States. He later divulges to Accelerator about the Trigger who then reports it back to Kamijou Touma and company, regarding GREMLIN's plans to use it to erupt a volcano.

With things calming down, Roberto takes Touma, Accelerator, Misaka Mikoto, and Leivinia Birdway to Pearl Harbor, where the Trigger supposedly resides. With Leivinia's suggestions, they simply walk into the base and orders the grunt working (Nike Canox) there, knowing that Saronia would only require to control higher ups, this is confirmed when a military officer (Bax Silver) enters the based and complicates Saronia's plans. Later, with Touma and Mikoto, Roberto checks one of the cargo planes, wherein they discover Saronia herself. Here, Roberto is given protection by Mikoto, as Touma does battle with Saronia with back up from Mikoto. Eventually, after Mikoto destroys several of the containers, Saronia discovers that Trigger isn't here, shoots the pilot and parachutes out of the plane. After checking up on the pilot's condition, Roberto, Touma, and Mikoto states to the pilot that they would leave him behind, and would require him to make an emergency landing instead of crashing the plane. They are rescued just in time by Arc Daniels to see the eruption of Kileau, though they realized it is much more downplayed than they expected. They later realize that the use of Trigger for the eruption as well as the Narwhal anti-ship missiles used to attact their company after being rescued was used to isolate the entirety of Hawaiian Islands for a much bigger purpose.

While resting during the Fall of Pearl Harbor, Roberto discusses with Touma, on how he suspects that many of the people working for Saronia and part of his government may not actually be controlled by magic by Saronia at all. Sowing the seeds of doubt on Touma's mind, as he rethinks Birdway, Cendrillon and Saronia's actions. Roberto then speculates that Saronia's true power may not be mind control at all. Roberto further states that the mercenaries that GREMLIN hired for the invasion of Hawaii maybe Trident, due to the technology used, and is one of the largest privitized military corporations in the world. After using the Imperial Package, Roberto states that the most likely person who has assets outside of the United States that could hire an army such as Trident would be the media queen, Olay Blueshake.

In a phone conference with the rest of Leivinia and Touma's group, he discusses Free Compound Eyes, a supposedly defunct free camera service which can be accessed by the search engines owned by Olay, maybe used to monitor their actions. Roberto further provides evidence to Olay's involvement by stating that Olay is as powerful as an entire house in Congress. Roberto continues his explanation that Olay tried to get herself elected but due to the onset of the Third World War, was unable to direct the country to the ways she wanted, and maybe the reason why she contacted with GREMLIN and Trident. Roberto states that she cannot be arrested as her current whereabouts are unknown. He later learns that Roseline has begun her move against Olay by gathering troops in order to make Olay's daughter, Lindy Blueshake, as a bargaining chip against her, with the variable that the troops may kill her. With Touma's determination, Roberto agrees to get to Lindy first before Roseline.

Roberto accompanies the entire Leivinia company, and uses the Imperial Package to find Lindy's current whereabouts. He is later part of the team for Lindy's rescue along with Shiage and Leivinia. They are later delayed as Roseline's troops are in a military engagement with Trident troops, leading with the latter's decimation and allowed Roseline's troops to take control of one of the northeastern beaches in Kauai, allowing them to search for Lindy in earnest. They later arrive at Lindy's residence which was in the process of being overtaken by Trident, however, Roberto managed to successfully collect Lindy at the cost of her manservant, where Roberto states that he will be much safer if he was not with Lindy. Mikoto later rendezvous with them, whither Roberto gives Mikoto advice to woo Touma, after she haphazardly mentions mentioning giving a gift, much to her consternation. She later tries to stop a tank while Roberto and company brace themselves from Cutter bullets, figuring out it maybe members of his countr's military attacking them. With their transportation wrecked, Roberto and Shiage are dragged off, while they take Lindy by marines. Although one of the marines were hostile and tried to attack Roberto, the large part of the unit led by Corporal Martin Flowers were allied with Roberto. He later calls Roseline to tell her to lay off her search for Lindy in order to use her against Olay, and states that they need only to subdue Trident's commander in order to stop Trident. Roberto arrives along with Roseline to confront the commander, Cinesic Evers, and forces him to back down his forces, threatening the future of Trident and allies attacking the United States with a threat of being slaughtered by them. However, Cinesic does not acquiese and instead orders all his troops to converge in Napali Coast and support Saronia. Later, after Saronia is defeated by Touma, Roberto once again tells Cinesic of terms of his surrender, lest they face a more brutal punishment, which the latter agrees to.

Roberto later returns to a hotel along with everyone, reporting on the missing GREMLIN operatives in Trident uniforms. Roberto later laments on Olay still being uncaptured, however, he uses this opportunity of her being missing to transfer all of her companies assets to Lindy, her daughter, putting Olay in a tough spot, without allies and without money.

Design evolution
Roberto Katze's design remains the same throughout the series. According to Haimura, he toned Roberto's "intensity" in order to lessen the similarities between him and Misaka Tabigake.

Quotes

 * (To a reporter in NT volume 3): "When I truly go after a woman, I give her such a memorable experience that any previous complaints are blown away."
 * (To Accelerator in NT volume 3): "I’m the goddamn president."
 * (To Cinesic Evers in NT volume 3): She uses those techniques that a certain sadistic British princess (who would make a good tsundere) showed us during British Halloween and that we saw all too much of during World War 3.
 * (To Misaka Mikoto in NT volume 3): "She’s right, girl. If you want to get yourself a guy, you need to change into a skimpy swimsuit and have a beer in one hand. All you have to do then is press your chest up against him and undo your bikini. Your point will be even more obvious if you do it near a beachside motel."
