Invaders from Irk (Invader Zim reboot)

Disclaimer: "Invader Zim" is created by Jhonen Vasquez and currently owned by Paramount. This reboot concept is a retelling of the Invader Zim series that may be slightly different from the original premise. Some or not all source materials from the original series may be included here, fan discretion is advised.
Premise: The infamous planetary-conquering race known as the Irkens have begun their "Operation Impending Doom III". However, over the years due to inner conflict between multiple Almighty Tallest base on their equally measured heights and their noncooperation in sharing their power over their empire, the Irken empire has been divided to at least around 5-6 Irken divisions based on their paks' colors. Because of this, the operation have grown into a competition to see which Irken Invaders is the more competent, and the colored-Invaders who conquers the most planets will have their respective Tallest to be declared "Highest Almighty Talleresque" and given absolute virtual power over the entire Irken empire. Due to their feared reputation throughout the galaxy, many alien planets and species have been more prepared and cautious with the Irken invaders and have been more resilient against the Irken Invaders ever since "Operation Impending Doom II", so to retaliate this, the Empire now has two other Irkens to assist the main Irken invader in the main Invader's mission goes "awry" due to certain planetary conditions along with anything happening to their SIR units. The Irken Empire also holds occasional events when the many Irken Tallest gather to announce their respective Invaders' progress and debating against their opponent Tallest's leadership traits and qualities compared to theirs, in exchange to gain more Irken followers towards their ideal Empire rule.
Characters
Zim: A egotistically unstable yet military-skilled Irken invader under the Red Irken Division. Zim's first mission was misinterpreted that not only was he trying to destroy and conquer his "assigned planet", but the homeplanet of the Planet Jackers, where one of the previous Tallest were negotiating a treaty with them but was killed during the process by accident along with the Planet Jackers' leader, unbeknownst to Zim. During "Operation Impending Doom II", Zim ruined the Irkens' invasion operation when he broadcast himself through the Gargantis Array, announcing Irk and numerous planets to fear and cower towards him and his race coming to invade them, which only makes the invasion slightly more difficult for the Irkens as many alien planets prepared themselves for the Irken invasions, which were cancelled due to Zim's intergalactic broadcast. Zim finally returns to the third invasion operation, wanting to convince his leader that he more competent and focus on his invader purpose he "trained" for, to which the Red Tallest reluctantly obliges (mostly knowing that Zim is so persistent he will not stop no matter what punishment is thrown at him) and gives Zim one last chance to dominate a "test" planet (Earth), letting him how he will take control of it as long the planet itself is still intact to take over (also the Red Tallest's advisor suggested him Earth as it has high levels of H2O, which is highly acidic to Irkens and hopes it would drive Zim to the brink of death).
Zim is assigned as main invader and captain of Red-Team 13, with two other (failure) Irkens, pilot and med/tech officer, and the disfunctioning SIR unit GIR. Blinded by his own ego, he tends to have difficulty in focusing on plans and tactics regarding his invasion mission, but his Irken military training can be proven resourceful both shooting and hand-to-hand combat when situation comes with dealing against enemies and keeping his own team alive and functioning. He holds no empathy or care for his own team despite the Red Tallest disposing to them as his assigned crew, but regardless he later acknowledges that he cannot succeed his "beta-mission" alone without the cooperation of his crew, so he makes sure to keep them out of harms way from aggressive humans, Irken rivals, and enemy alien races until he succeeds his mission and proves his worth to the Irken race.
