Like his rookery brothers Brooklyn and Broadway, Lexington was hatched in the Wyvern Clan rookery in the year 958. He and they became close friends during their childhood, thus forming the trio. They and Bronx survived the Wyvern Massacre of 994 thanks to their having been confined to the rookery for getting into a fight with some of the humans, and so were not found and shattered by the Vikings. Lexington and the others, however, were afterwards turned to stone by the Magus, and remained in stone sleep for a thousand years, finally awakened when Xanatos moved Castle Wyvern to the top of the Eyrie Building. ("Awakening" Part One, "Awakening" Part Two)
Lexington was fascinated by the modern world, and particularly its technology, and remains so still. Even before his long sleep, he was intrigued by complex mechanical devices, such as the catapults that Hakon and his Vikings used to attack Castle Wyvern. Upon his awakening, he eagerly investigated the technological devices of New York in the 1990s, such as computers (Xanatos donated the laptop that Lex is typically seen with at the Clock Tower, and Lex went back for it when the clan originally left the Eyrie Building) and Vinnie's motorcycle (with disastrous consequences for both the motorcycle and Vinnie). He also learned how to construct a motorcycle out of spare parts (although it blew up not long afterwards), and later rebuilt the Pack's helicopter to make it more effective to be able to capture Jackal and Hyena. ("Awakening" Part Three, "Temptation", "Her Brother's Keeper")
Lexington has since become the clan's technical expert, who works out how to disarm advanced security systems, access information from computers, and so on, whenever the clan needs his help with such things.
Alongside Lexington's passion for things mechanical, he holds also a deep grudge against the Pack. Shortly after the clan awoke in New York, Lexington (alongside Brooklyn and Broadway) became fascinated with the Pack, and believed them to genuinely be the valiant heroes that they played on television. He therefore sought them out, hoping that they could become new friends and allies to the clan. The Pack pretended to accept his friendship, however, in order to lure him and Goliath into a trap for the fun of hunting them. Lexington was crushed at the discovery of how they had betrayed them, and hated them with a vengeance ever since. ("Thrill of the Hunt") Indeed, his grudge against them has been so bitter that it has led him to occasionally forget his priorities, and endanger himself or his fellow clan members.
Lexington’s feud with the former Pack member Fox has ended, however, thanks to a third keystone in his life; his close friendship with Alexander Xanatos. Lexington and Alex first developed their rapport when Alex temporarily possessed him in order to use his body and vocal organs to cast "soul transference" spells involving the Coldtrio. ("Possession") Lexington warmed to Alex as a result and this process deepened further after the clan moved back into the castle. For Alex's sake, therefore, Lexington has made peace with Fox. ("The Journey") His current attitude towards Dingo is unknown, although it is safe to assume that he still dislikes Jackal, Hyena, and Wolf, the three unreformed members left of the original Pack.
In November of 1996, Lexington, along with Hudson, elected to go with Macbeth when the latter sought the clan's aid in safeguarding the Stone of Destiny during its trasnport from Westminster Abbey in London to Scotland. After a delayed awakening in London, both Lexington and Hudson got a taste of the gargoyle version of jetlag ("The Rock"). Lexington and Hudson later met up with Griff and two other gargoyles of the London Clan; Constance and Staghart, who, along with King Arthur, arrived for the same purpose of protecting the stone. The group of gargoyles was later attacked by Coldsteel, Coyote 5.0, and a Steel Clan and Iron Clan robot for reasons yet unknown. ("Rock & Roll")
Lexington seems to have formed a strong friendship bond with Staghart, whom he's elected to call "Amp". We have yet to see how their relationship will progress.
At some point in the future, Lexington will play a part in the founding of the Lexington-Xanatos Corporation. The details for this are as yet unknown, however - beyond the fact that the LXM robots, which this corporation will be manufacturing by 2198, are modeled after him in appearance.
In Puck's Future Tense world, Lexington initially appeared as part of the resistance against Xanatos, decked out in numerous cyborg replacements and armor, and was truly a cybergoyle. He exhibited a resentment and hatred of Goliath for his abandonment that festered into a murderous megalomania. It was later revealed, however, that Xanatos had died years before, and Lexington - using the Xanatos Program as a front - had conquered the city and set in motion an unstoppable plan of world conquest.
Lex lured them to the castle where one by one, Broadway, Brooklyn, Demona and Angela were destroyed, and he very nearly killed Goliath in his Xanatos guise, but in an act of supreme will, Goliath survived the incredible damage inflicted on him and destroyed the Xanatos form. After finding out that Lex was the true mastermind, Goliath tried to stop his plan of world conquest, even destroying his body in the process, but was too late.
Lexington is the smallest of the trio, and because of this, his large eyes and his reedy voice, looks younger than he really is. His most distinguishing feature is his wings, which are attached to his arms in a web-like structure, evocative of the wings of a flying squirrel. When he desires, Lexington can fold his webbing to allow him to wear regular human clothing, but he must remove them in order to glide. His wings are pierced, which allows him to wear a loincloth. He has khaki-colored skin, and a hairless head. Greg Weisman has revealed that Lexington is gay, "although he hasn't fully realized [it] yet." Greg did confirm at CONvergence 2011's Gargoyles Panel that Lex has a crush on Staghart.
Lexington received his name in 1994, soon after his awakening in New York, naming himself after Lexington Avenue. A common nickname of his is "Lex".
Behind the Scenes
Voice Actor: Thom Adcox
Lexington's predecessor from the comedy development was a gargoyle named Lassie. Lassie was more of an idiot savant than Lex, capable of being equally enthralled by a laser gun or a shoelace. Interestingly, the Lassie character at one point had a design that was more reminiscent of Brooklyn.
Another name considered for this character was "Wedge".
