YMMV / Mario Teh Plumber

• Diagnosed by the Audience: His internet persona seems to have a serious case of intermittent explosive disorder^note colloquially known as "anger issues", reacting with disproportionate rage to things most people wouldn't even notice, much less care about. His persona is also highly narcissistic; he acts ridiculously over-the-top in his "reviews" to get attention, and thinks his own opinions are superior to everybody else's while simultaneously feeling insecure, to the point where he is enraged by disagreement, let alone criticism.
• Fandom-Enraging Misconception: Taking his videos seriously. This was more common than you'd think in his earlier years—as a side effect of the Sonic the Hedgehog franchise's infamously divided fanbase with a significant Vocal Minority of unpleasant fans—but it has since become increasingly accepted that MarioTehPlumber is a Troll whose opinions are either fabricated or exaggerated, and believing his behaviour is genuine will elicit eye-rolls nowadays, especially from those who enjoy the demented hilarity of his over-the-top persona (which is admittedly his entire fanbase now, more or less).
• Nightmare Fuel:
  • "Sonic's Word On Sonic Colors" features a hilariously over-enunciated impression of Jason Griffith's Sonic promoting the then-upcoming Colors, offset by him proclaiming the aforementioned game will be "shit". Of course, if by "proclaim", you mean "screech like a banshee as loudly as possible", you wouldn't be far off.
  • "Sonic Generations level Impressions" has him react to the (ultimately false) rumor of a stage in which the player takes control of a Werehog-ified Classic Sonic by threatening to singlehandedly bomb Sega's offices. The way he borders on Angrish as he says it doesn't help one bit.
  • Some of his video game "reviews", most notably the one of Spyro: Year of the Dragon, depict him destroying the game in question à la the Nerd. Unlike the Nerd, however, the way he goes about it is more unsettling than it is funny, with him repeatedly smashing the disc with a hammer, throwing the case around, and even going as far as to rip what's presumably the instruction manual apart in a fit of rage. Needless to say, this was something that did not go unnoticed by many a commentator at the time:
    Weasel: Shit, dude, did the game kill your parents or something? Chill out!
• Overshadowed by Controversy: Outside of the Sonic and Nintendo fanbases, most people have heard of him only because of his purchasing of over a hundred Rosalina amiibo in 2015 because he hates her "Hentai" character design (his words) and to spite the character's fans who wanted one amiibo of her. This incident was reported by video game journalists and immortalized him as a Psychopathic Manchild. Not that he ever had an even remotely decent reputation in the first place.
• So Bad, It's Good: His Internet persona is completely insane and not to be taken seriously, and his fans tend to enjoy him solely for this reason. Justified, as he's a Troll.
  • He screams into the microphone and generally acts like a spoiled child.
  • He drops Cluster/Atomic F-Bombs every other word.
  • He sees ridiculous sexual connotations in mundane objects.
  • He doesn't do his research and may not even play the games he covers.
  • He insists the most important aspect of any video game is the character design, and almost always begins any "review" he makes with discussing the character design before discussing the actual gameplay.
  • He lets his own personal feelings towards certain companies and franchises get in the way of whatever valid points he may bring up in his reviews.
• Vindicated by History: While his videos are still widely agreed to be low-quality, nonsensical ranting to this day, much of the vocal contempt towards MarioTehPlumber has gradually died down over the years with the growing consensus that he was a Troll all along^note During his earlier years on YouTube, many viewers believed that MarioTehPlumber's behaviour was genuine because of the infamous reputation of the Sonic fanbase, made worse by a significant Vocal Minority of obsessive and unpleasant fans. He has since managed to gain a small fanbase based on ironic appeal.
• What Do You Mean, It's Not for Kids?: While most of MarioTehPlumber's videos discuss video game franchises that are family-friendly in nature, the actual contents of his videos are anything but. That said, some of his videos have titles that give this away (e.g. "Why Splatoon is hentai and why Nintendo Sucks"), though most of them don't.
