History
Always dissatisfied with his parents' pressure to become a doctor, Greene decided to attempt a streaming career on the internet, describing himself as the world's first e-clown. Although he earned decent money doing this, he grew bored of it. He then attempted his hand at being a YouTube prankster, and although this went well, he soon found that this also got boring within a few months. Following many comments on his content calling him "deranged" and "psychotic," Greene came up with the idea that he would become a supervillain. He raised money for various cosmetic surgeries to change his appearance and began robbing banks in Midwestern America, where he was soon caught and detained by local authorities.
The Greedy Grinner
While in jail, he was given a special "gift" in the form of a nasal spray that contained noxious gas known as NOZ. He inhaled it and seemingly died, only to wake soon after to realize that his skin had gone green and his teeth had become jagged and sharp, as if they were made of silver. He also noticed that his previous cosmetic alterations had become exaggerated and goblin-like.
He breaks out of the jail cell soon after, using his saved streamer money to buy silver plated dental braces. He covers these in acid and uses them partially to cover his sharpened teeth, which had grown considerably in size. He then goes to a local casino and blows the rest of his savings on repeated high stakes gambles under the alias "Mr. Green." By the time he leaves, he is $500,000 in debt to the casino.
He now spends most of his days plotting large robberies and burglaries, hoping to someday pay back the debt he owes.
Rivalry with Vine-Man
A man named Vinny Vinicius had briefly worked at the casino Greene robbed. The robbery had put several of his friends out of work, including Vinicius. After gaining powers and becoming Vine-Man, Vinicius formed a personal vendetta against Greene. He tracked him to an abandoned warehouse in Gary, Indiana, where he found the Greedy Grinner Gang (who were all addicted to various narcotics at the time). It is currently unknown what happened next.
Appearance
Before his disfigurement, Greene was described as being a short man with brown hair and blue eyes. His face was described as "handsome," with a strong jawline. He was usually depicted as wearing a long black leather coat, gloves, and a runed medallion around his neck.
After inhaling the NOZ gas, he acquired green skin, a long chin, and sharp teeth. Greene's acid-soaked silver braces are usually held in place by duct tape on his chin. The acid slowly erodes the metal and gives off a foul smell. He says that his disgust with all "smelly smells" causes him to think of this as his ultimate weapon.
