Agent Darkbootie

Agent Darkbootie is the unofficial leader of the Swollen Eyeball Network, an organization of paranormal investigators and conspiracy theorists. Darkbootie is perhaps the one agent who truly believes that Dib (Agent Mothman) can prove himself to the rest of the Network, whose other agents often ridicule him. While also annoyed at Dib’s constant "Zim" babble, he has occasionally helped Dib in his efforts to save the planet.

On one such occasion, Dib seeks Darkbootie's input as he researches chaos emeralds during "Dimension Mix-Up," and Darkbootie helps by looking up their power signature (previously given to Dib by Doctor Eggman) and matching it with that of the emerald Dib locates later on; in doing so, he observes Dib's true competency in paranormal investigation, and now seems to have more trust in Dib's abilities— even believing Dib's talk of Zim, and his interest in these emeralds.

Following the City Invasion in "Dimension Takeover," Darkbootie and his fellow agents learn all that they can about the new threat known as the Xevians, discovering that they originated from Earth 100,000 years ago under the authority of a supercomputer named "GAMP," and that they now come from the planet Xevious— hence their new affiliation. Darkbootie conveys all of this and more to Sonic the Hedgehog and his allies upon their arrival, while also notifying them of the Xevians' capabilities and their motives in re-conquering the planet Earth. As the group at large suddenly falls under attack by the Xevians themselves, led by their new commander Tak, Darkbootie eventually manages to communicate to Sonic that Dib's wristwatch can transport them wherever they need to go; he then watches as Sonic, Dib, and the rest of their allies successfully escape from the area.

Agent Darkbootie later travels to Calvin's dimension, in order to warn him of the dangerous mission that Dib and Sonic are now undertaking; he tries to tell Calvin not to visit them at this time, concerned that the boy will be put in harm's way, in a situation much more perilous than the Hunt for the Chaos Emeralds. As it becomes clear that Calvin is not going to let his friends fight the Xevians without his and Hobbes' help, Darkbootie decides to let him go. Shortly after the two of them leave, Darkbootie receives a transmission from fellow agent Nessie, who tells him (in code) that Tak has infiltrated the Network; understanding immediately, Darkbootie transports himself to the Nazca Lines.

Here he finds himself within the Xevians' provisional base of operations, and later comes across a secret weapon beneath the lines representing a hummingbird; he discovers that it is meant to be a form of counterattack against the Xevians, and then realizes that past rumors of this weapon have now proven true. Understanding that the Xevians cannot access this weapon, and so must establish countless safeguards around it in order to prevent its activation, Darkbootie makes to inform Dib and his allies of its existence— but is halted by the arrival of Tak. As she boasts of her allies' invulnerability to weapons such as these, Darkbootie counters her remark by stating that the alliance of heroes she is now up against seems to be posing enough of a threat against her forces, and that soon they will learn of this secret weapon and use it. However, Tak then shoots Darkbootie with her Irken handgun, declaring that with him gone they will never know; with that, Agent Darkbootie's life is brought to an end.
