Dr. Kleiner

Dr. Kleiner is an Old Man scientist originally coming from Half-Life who appeared in SuperMarioGlitchy4's videos "Ssenmodnar 6.64 (100k special QNA Edition)", "Sonic The Derphog: Eggventure (GET IT!?)" and "SwagQuest".

Look
Dr. Kleiner is an Old Man, he then has a gray hair and is partially bald. He wears a white shirt marked with the green word "dsb", dark jeans, black shoes and also black glasses. In the video "Ssenmodnar 6.64 (100k special QNA Edition)", his glasses have blue lenses, and in the episode "SwagQuest", he wears a brown hat after Luigi tells him he looks ridiculous (see below).

Ssenmodnar 6.64 (100k special QNA Edition)
This is Dr. Kleiner's first appearance in SMG4's bloopers, in this video he appears in the last skit of the video (#15) as a nerd who is revealed to have been watching the video up until this point, and says it really sucks, not knowing SMG4 is right behind him. Eventually, SMG4 gets pissed, and tosses the nerd out the window.

Sonic The Derphog: Eggventure (GET IT!?)
In this other blooper, Dr. Kleiner appears as a news reporter on "Humans News" on a large television to whom Sonic is watching after this last one found it, in Human City. Dr. Kleiner reports that an alien (Dr. Eggman) has landed in Human City.

SwagQuest
When Luigi is not allowed to go to Mario's party because he doesn't have enough swag, he seeks lessons from Bowser on how to obtain swag. After a few minutes in the lesson, Bowser tells Luigi to change his clothes, to add swag. After four clothes changes, Luigi and Bowser settle on a gangster costume. Then, Dr. Kleiner runs up to Luigi and slashes his clothes off with his crowbar, causing Bowser to force Luigi to fight the Old Man, stating that he "ruined Luigi's swag". Luigi is afraid at first, but gains the courage to insult the Old Man, telllling him "You look ridiculous". The Old Man then gets angry and Luigi starts rapping. The Old Man reminds him that this is a fight, and a short battle ensues. The Old Man strikes Luigi with a Smashball, who counterattacks with a "Big Gay Dance." The Old Man then throws a fireball at Luigi, who ducks as it ricochets off a tree, blasting Dr. Kleiner into the air and causing him to crash into a boat, which sinks as Luigi does a short victory dance. The Old Man might dead.

Trivia

 * His name doesn't appear and isn't heard in SMG4's bloopers.
 * He's always calling "Hippie" to Luigi, in the video "SwagQuest".
 * He's always carrying a crowbar, except when he's in fight with Luigi in the episode "SwagQuest".
 * Despite being old, he seems to have a lot of energy in SMG4's videos. In fact, several characters, often old, are apparently stronger in SMG4's bloopers than everywhere else, like Dumbledore from the Harry Potter series, who appeared in the videos "Spells n' Wiztards" and "Ssenmodnar 8 (150k special)" (cameo).

Note
On this Wiki, we also call him "Old Man", but, in this case, he mustn't be confused with the Old Man Hobo, and also with the Old Man who appeared in the blooper "Cooking with Bowser and Mario 2!" in the part "How to cook: Raisins?".
