John Egbert is one of the main characters in Homestuck. He is a boy who, according to this page, has not been given a name until his thirteenth birthday; however, this is just a framing mechanism. In the past, he has ended letters with "-ghostyTrickster (john)". While originally given the name "Zoosmell Pooplord", the game rejected it and settled for John.
John uses an online application known as Pesterchum to communicate with his other tech-savvy friends. His chumhandle is ectoBiologist. It used to be ghostyTrickster, but he changed it to avoid the Trolls. Oddly, he chose the name ectoBiologist based on a comment by one of the trolls.
His God tier title may be a pun on his associated classical element, because interchanging the first and last words produces "breath of air".
His web browser of choice is Typheus, who coincidentally is the mate of Echidna, the namesake of Jade's web browser.
John's associated Classical element is air, and his Associated Item is oil.
John was raised by his Dad, who was genetically his half-brother through ectobiology shenanigans. His dad was generally supportive of his interests, but also had an unhealthy obsession with Harlequins (or so John thought). John made three friends his age over the internet, who would go on to play Sburb with him. The story begins on his birthday, when his copy of Sburb arrived. He also got an awesome Bunny from his friend Dave Strider . He set up the first connection with Rose Lalonde as his server.
Despite his penchant for video games, he initially did not have a firm grasp on the concepts of Sburb and rarely understood what was going on with some of the more technical commands, he lacked any sense of understanding game play rules, nor could he fathom the abstract nature of Captchaloguing. Despite that, his level of understanding the cipher-based technology behind Punched cards is remarkable. As he is one of the players in Sburb, John's peril quickly escalated as the game progressed, and he had limited understanding of what was going on or what he needed to do.
Personality and Traits:
John's physical appearance could be described as a kid with black messy hair. He has an obvious nerdy look about him, a trait he may have inherited from his bucktoothed grandmother (Who actually turns out to be genetically his mother, while his adoptive father is actually his half-brother). His outfit usually consists of a white shirt (though the shirt modeled after John's you can buy in the store is light blue) with a picture of what appears to be Slimer from Ghostbusters but is in fact a Japanese knock-off, shorts and a belt, and black sneakers. He wears a pair of rectangular glasses. He has briefly worn other items, such as an attempted disguise, and for some time he wore a teal suit with the green slime ghost on it, a tie, and long pants. This was a combination of the suit (a birthday present from his Dad), his normal shirt, and the "Wise Guy" book created during John's last alchemization session. He then began wearing the Junior Ectobiologist's Lab Suit, a light green lab coat over dark green shirt and pants, with yellow shoes and a green slime ghost belt. Vriska Serket later outfitted him in an ensemble reminiscent of her own. After achieving the level of god tier, he wears an all blue ensemble featuring a hoodie with an abnormally long hood.
John's interests are movies, web comics, and video games. He enjoys paranormal lore and magic tricks, the latter of which he also performs. He owns a computer and likes to make programs, no matter how bad they may be. He is left handed (when not spriteflipped), allergic to peanuts, and has a long-standing hatred of the brand Betty Crocker. He can also play the piano quite well.
His room has various items to support his hobbies, such as a Magic Chest filled with trick objects. His walls are littered with posters of movies, web comics, and video games. Notably, his collection of items when colored are typically green, but John associates himself with the color blue.
