Gravitina decides to help Zurg wipe out Star Command.

After an inspection of the planet Rhizome's bio-defenses, Team Lightyear are all given energy plants by Professor Triffid. Booster picks up a red one instead of a white one. The plant is slowly taking over the ship and then Star Command itself. XR has begun to give unauthorized tours for Buzz Lightyear fans behind everyone's backs.

Buzz is impressed by rookie Flash Flemming, much to Booster's chagrin. Gargantia's ambassador Ursona Major contacts Star Command in order to join. But it turns out that there are rebels, who oppose the idea of Gargantia joining Star Command and thus possibly losing their individuality.

Warp Darkmatter hijacks a cargo ship which is carrying NOS-4-A2's coffin and Team Lightyear comes to stop them.

Warp Darkmatter and Buzz find out that there is an odd implanted device within both of them. So they work together to discover who gave them the implants.

Buzz and XR respond to an emergency distress from Sentilla looking for a downed cargo ship of Hyper Bombs.

The crystals for Crystallic Fusion Generators (the primary power source for almost all Galactic Alliance technology) are mined on the landless ocean planet Bathyos; an anti-air breather movement, hoping to cause an embargo that will force the Galactic Alliance to bow to the will of the Bathyosians, is lead by Gularis, a shark-esque big-wig native of Bathyos. The movement is taking terrorist actions, causing ""accidents"" to happen in the crystal mines, but Team Lightyear is called in as a safety measure, and they uncover Gularis' plans.

One of Zurg's Brain Pods (Number 13) goes AWOL, so Zurg hires the Boba Fett-esque bounty hunter Shiv Katall to track him down; Buzz turns out to've been Shiv all this time, in order to make defectors from Planet Z seem to be dead, when they're really in a witness relocation program; Buzz gets found out, so Commander Nebula has to do the Shiv-thing (...which he USED to do, before Buzz came along...), in order to make Zurg regain trust in the existence of Shiv Katall.

Mira, Booster, and XR are all nominated for the Rookie of the Year award. The three compete with each other to impress Buzz, which Zurg uses to steal a new matter transporter.

XR downloads Star Command Mainframe to prevent the system from crashing (due to Warp Darkmatter using info-stealing techno-ticks); Zurg heists XR in order to gain Star Command classified information; XR uses techno-ticks to help HIM out.

Cosmo gets K-3000 Uni-appliance for Cosmo's Diner (the diner that Team Lightyear seems to spend too much time at); the K-3000 Uni-appliance is an experimental device that absorbs one's kitchen appliances into itself, and is able to use them all due to its powerful, experimental energy source and its ""liquid steel"" structure (...possibly constructed of nanobots?...very much like a robotic shoggoth, from H.P.Lovecraft's stories...). NOS-4-A2 senses the power within the K-3000 when the Courier delivering it passes close to the abandoned ship that he was residing in, trails after it, and takes control of the K-3000, all of Cosmo's restaurant equipment, and then all of Cosmo's Diner. Team Lightyear is in the process of returning Professor Triffid to his home planet, Rhizome, after a failed attempt on his part to convince Star Command to incorporate ""organic vegegenetic technology"" into their systems, when they receive the distress call from Cosmo.

Crumford Lorak hides in Senator Banda's fishtank (ambassador from Bathyos) in order to gain and sell Galactic Alliance secrets to the Raenoks at the Luma 9 Station. Booster is talked into purchasing a Yukari-pod; Yukaris, it turns out, are small creatures which take on the form of their ""mother"" (whomever is around the egg in the latter stages of development), but are quite ravenous and reproduce at an astounding rate (...imagine a cross between ""Gremlins"" and tribbles...). Booster's ""fuzzy buddies"" (...the name that the salesman was marketing them under, since his ""demo model"" was one that had taken on a fairly cute form...) ravage 42 and eventually all of Luma 9 Station, when Team Lightyear arrives there in order to help serve as protection for the ambassadorial delegates that are meeting there. Booster's (and thus the Yukari's that were imprinted from him) love for chocolate saves the day, by helping to round up the Yukaris and by using them to then subdue the Raenoks

When Brain Pod #57 defects to Star Command, Zurg hires Romac, a Tangean Grounder bounty hunter -- and Mira's ex-boyfriend -- to bring him in.

Answering a distress call from a planetoid within ion storm, Buzz encounters Spyro Von Madman, and his daughter, Bonnie. Professor Spyro Von Madman, previously known as Spyro Lepton when he worked with Star Command, was a scientist who had come up with the notion of equipping Space Rangers with a semi-organic energy-absorbing crystalline form, thus resulting in what he called a ""cryborg"" (...very much like the concept behind Star Trek's Borg, but with a crystalline basis), eliminating the need for the Pulsar 400 Envirosuit & Battle Armor that is standard issue for the Space Rangers. Spurned by Star Command, Spyro had gone off into seclusion to further his research. When Spyro had worked for Star Command, he and his daughter were acquaintances with Buzz, and it would seem that Bonnie has been carrying a torch for Buzz all these years. She helps him to escape her father's Cold Slab of Revenge, and to bring her father in. While in jail, Spyro sees Bonnie & Buzz walking together

Team Lightyear get separated and meet up with the last Beletor and the last Krnozian, who're warring over possession of their home planet.

Zurg nabs an exhibit of an extinct species of large, Alien (as per the movies)-esque insects, planning to resurrect the species in order to help him in (...what else...) take over the galaxy. Dr. Ozma Furbanna is roped into helping Zurg revive Alien-style bugs, by having her scientific morals preyed upon. Zurg sics the bugs on Capital Planet. Before things can get too out of hand, Team Lightyear discovers that the bugs can be stopped by belly-tickling (...it over-rides their nervous system...), and with that they manage to save the day.

Professor Reddschift, Mira, Booster, and XR are pinned down by Zurg's hornets, who are attempting to kidnap Prof. Reddschift. The Prof. is worried that Buzz won't be able to arrive in time to save him from capture. To try to buck up his spirits, Mira relates her first encounter with Buzz, back before she enlisted in Space Ranger Academy. King Nova had been nabbed by Zurg and his Hyper-Hornet in the midst of a conference attempting to convince Tangea to join the Galactic Alliance, but Mira & Buzz managed to defeat Zurg, save King Nova, and convince Tangea to join the Alliance (and Mira to join the Space Rangers). This proves to be less than impressive to Reddschift. Booster then relates HIS first run in with Buzz. Zurg had attempted to take over Jo-Ad with his Mega-Hornet, thus cutting off food supplies to most of the Galactic Alliance. But with Buzz's timely arrival, and with Booster's strength, they managed to stave off Zurg. Again, Reddschift isn't impressed. XR then tells H

While Buzz is testing out the LGMs latest invention (...some sort of space-scooter...), the LGMs are struck by a need to ""heed the heed"". As if hypnotized, they all commandeer a ship and fly off. While Zurg is attempting to dispatch hornets to defeat Buzz and capture the space-scooter thing, the same thing happens to the Grubs. The Grubs and the LGMs arrive on a distant planet (...Buzz and Zurg catch up in a few minutes...), where a giant, intangible, glowing head named Guzelian the Alien (...a member of the Heed, an advanced race that has transcended physical form...) tells them that they must work to bring peace throughout the galaxy. The Grubs return to Planet Z, the LGMs return to Star Command, and both of them then proceed to dis-assemble any weapons or armaments that they have, in order to issue in this new age of peace. After a charming little ditty written and performed by Mr. Idle, entitled ""Let's Make Peace!"", Buzz grows wary of Guzelian's intentions.

Mira is assigned to accompany the Galactic President and her advisor to a conference. They are shot down over Karn and are forced fight for survival.

When Zurg steals the Chrono-Disruptor from Santa, Buzz and the gang must help Santa to save Christmas.
