"Glen" is the overarching antagonist of the Big Lez Show, serving as the unseen overarching antagonist of Seasons 2 and 3 before appearing in a flashback of Clarence's and later revealing his role in the story in Season 4. He is possibly a human or other unknown form of alien, as he is not one of the listed Six Kingdom Cumians to have survived the destruction of their planet.
Glen as seen in Clarence's flashback.
His first appearance was a flashback of how Doctor C. became Clarence, and was one of the scientists working for him. During Doctor C's surprise party, Glen warns him that he heard some screams coming from his office (as well as stating it smelt like shit in there). After investigating, Doctor C is mutated into a hideous shrivelled green form that would later be known as Clarence. Shocked and disgusted, Glen and the other scientists throw Doctor C (and his experiment) into an escape shuttle. He is then sent to drift through space before crash landing on Choomah Island, where he accidentally caused an outbreak by dropping his research into a massive pit that would later become the Hive.
It is unknown what Glen did after this, but it is likely he founded the company that produces 'Glen Dolls' that became popular in Australia. Lez was known to have collected them for years, but after hitting a jackpot at a slot machine he invests massive amounts of money into making a 'Glenworld', a massive collection of Glen Dolls along with miniature buildings, props, vehicles and other objects that creates a city. Glens have such jobs as principals, managers, accountants, business owners and lawyers, and their voice lines express how they live their lives working for paper with no value before dying.
During Choomah Island 3: Denouement, Glen makes a surprise appearance and states he has been working with King Laranox, stating that Lez had indirectly been funding the whole operation by buying massive amounts of Glen Dolls, which he collected to form Glenworld. He then goes onto to betray Laranox and ejects him and Lez out of his spaceship before flying away.
A Glen doll.
It can be heavily implied that Glen had been planning the Choomah infestation of Earth since before the events of Doctor C's origin story. There is supporting evidence of this throughout the series:
- On CI3, Glen has extensive knowledge of how the Choomah's worked with turning into a mass, which in space would expand to become a planet. This would imply that Glen knew more about Clarence's experiment than at least the other scientists did, and possibly even Clarence. Clarence's lack of apparent knowledge at the time of CI1 could be contributed to the Biz Lez series being in its infancy and the story still being fleshed out for the future.
- Glen was the one to report that the experiment was screaming. The container looks to have been intentionally sabotaged and it is plausible for Glen to expect that Clarence would have touched the formula, going through the transformation which would get him exiled. The experiment was actually sabotaged, which Norton tells Lez here just before Lez kills his brother Norton.
- The escape pod may have already been configured to travel to Earth from the beginning and it was always intended for Clarence to take the formula to Earth and have it spread and gestated. This is supported by both Clarence and Lez's backstory state that they drifted in space for a long time (Clarence was floating in space "for like 8 years" and Lez was "drifting to space for an Eternity before crash landing in Australia", which is an obvious exaggeration that still implies a long period of time). This would imply that it takes roughly 8 years using Kingdom Cumian escape pod technology to reach Earth, an obvious target for these pods to land on due to it being able to harbour life.
Glen may have had a hand in the events on Kingdom Cum and Big Lez's exile to Earth, and planned the events up to CI3 with Laranox.
- Laranox and/or Glen could have easily theorized that Lez and Norton would attempt to screw each other over in an attempt for the brothers to enhance their chance at being named the successor, setting up the circumstances which would allow a legitimate exile. Lez's apparent fondness of action figures could have been discovered by either Laranox or Glen, which explains the fact that they upped the prices of Glendolls because they apparently knew Lez would spend money on them to indirectly fund their plans.
As shown in CI3, Lez has the power to defeat Laranox and put an end to their plans. The only way for them to proceed with tyrannical conquering of other life-harbouring planets would be to get rid of Lez, and Earth would be a suitable location since it is well behind in technological advancement. Glen's plans may have also included manipulating Laranox from the beginning. There are events which would support this, although it's also possible that at some point Glen decided to go into business for himself, intentionally sabotaging experiments into weaponising Choomahs the day after their exile. The end goal of the Choomahs is that they turn into a planet, so by devastating the planet so much, Glen twists Laranox's arm by forcing him to blow up his own planet to prevent the plague of Choomahs spreading across planets in a "grey goo" scenario. This now gives cause for Laranox to want to conquer Earth - so that he can restore a rule over another kind of people.
Its most likely that King Laranox exiled Lez and Norton to Earth because he wanted them to survive, but not damage their planet further. It's possible that in orchestrating the exile, Glen fed the notion that Lez would come back for revenge and Laranox needs to deal with Lez before Lez gets Laranox.
Glen's current whereabouts are unknown. It is implied that he escaped on the ship and was not caught in the nuclear blast that destroyed the Island. In the years since Lez's death he hasn't come back to Brown Town, presumably due to no longer having business with its inhabitants (although Sassy and Donny should know, since they know everyone in the universe).
