EmpLemon (formerly "EmperorLemon" until 2016) is a YouTube Pooper and (probably one-time) editor. He started in 2010 but did not hit it big until his most popular video "The UNCredibles" was released in 2013. In regards to that poops popularity, he for the next several years made many popular YTPs of the Pixar film library until getting sick of it and retiring the genre with the "Frying Nemo" quardology in 2014 being the last. After that, with his name change, he adapted a far more nonlinear style that relied heavily on using internet and YTP memes, old and new, in a free-flowing vaporwave-esque style, as well as much mockery of anybody who dislikes the new style.
In terms of editing, despite having only did one edit, said edit was so popular, it along with Goop Videos' The Camping Episode edit, is considered to define what a popular edit is in the 4th generation of editing.
His first acknowledgements of editing came with a short video uploaded in July 2016 wherein he used audio from MovieEdits' "The Bet" edit overdubbed with WWE footage. Over the span of the "Emp" era, this would be followed by many many more references to that particular edit, the whole list of which is on MovieEdits' wiki page.
His first (and probably only) edit was done as his April Fools 2017 prank, of the SpongeBob episode "Squilliam Returns" and dubbed "Chad Warden Returns". Although the edit's visual quality was deliberately bad to give a throwback to the "2007 style" (complete with an Unregistered Hypercam watermark), much like Goop Videos' similar April Fools joke, the edit itself was legitimate. The choice of soundclips was almost entirely sounds used in The Bet (sometimes including words from the actual Drake & Josh episode) and LickMyNoseHAHAHA's "Krusty Towers" edit, memes, and soundclips associated with Lemon's popular running jokes. The video was received with almost unanimous positivity from his fans, and became one of the most popular edits of the year, thereby paving the way for a retro 2007-2008 style to be considered necessary for a "mainstream edit", thus triggering Generation 4 of editing.
