A few games Mike streamed. Prinny 2 and most RPG Maker Horror games.
As of late, the chat ITSELF has been getting to this point, possibly by certain videos sent and their (Lack of) maturity. Some people even want Mike to remove the chat off his videos, despite him keeping it on the stream and videos for archiving and to make keeping track of the chat easier.
Cringe, which has been a staple seems to be getting divisive as of late possibly due to the amount Mike has been finding. It doesn't help that the cringe videos sent to Mike either have repeat footage or in some cases, truly disgusting stuff that is questionable in terms of Youtubes guidelines.
To a lesser extent, Mikes streams themselves. Despite most of this TV Trope page revolves around his streams just as much as his Youtube channel, a few people think Mike should go back to being a full time Let's Player citing various reasons (Unable to attend streams for whatever reason, not liking the people there, streams being too long, simply liking his L Ps better) while other people prefer his streams more.
Bern, despite her past butt monkey status and constant trolls targeting her, is popular in the chat to the point of being created in Wrestling Revolution and getting a character in Toilet In Wonderland named after her. As well as a Club Penguin pet.
Mc Whimple despite only appearing in one stream has become a staple character in the streams. Same goes for Pasqually.
Glacken is also one despite his rare streams due to his quirky personality and his love for cornpops.
Bingo the Clown has become this in quite a few circles of the fanbase.
Redbear quickly became popular in 2015.
Same with Reisen. It's funny how due to the user appearing in the chat, the amount of Touhou references in the stream exploded.
The Fat Swordsmans Cameraman is also one because of the stuff he has to put up with B Billy K and in one case got badmouthed by Bbilly.
In one of Spots streams, we got the Running Woman who when Spot was playing an adventure game, she was on a treadmill. However she ended up breaking the stream due to her running and Spot eventually had to quit the game.
On Berns streams we got Judgement Boy for his Mind Screw morality choices and his own "song" of sorts whenever he arrives.
He-man and Kenshiro have became Stream characters on their own due to Mike using their shows respective themes.
A Youtube user by the name of 'Tony', who is a kid with amazingSinging whom appeared in a few cringe compilations.
Face of the Band: On the streaming end, a good amount of Mikes chat doesn't realize other people other than Mike himself do streams either because they don't join the forum or don't bother looking up others than himself.
On the chat regular end, it seems like only the more vocal users like Bern, Spiffy, Reisen, and Redbear get attention while the other users, who do contribute too end up getting pushed aside into obscurity.
"Funny Aneurysm" Moment: It was joked about how Crystals went on a hiatus because he died... and then it turns out that the reason he hasn't been on was because Roger, his best friend, died.
Growing the Beard: As time went on, the quality of Mikes streams went better due to him changing mics and streaming programs and allowing people to interact with him in the chat. It went full force to what it is today in 2012 when Mike began to bring in Stream Characters to lighten the mood.
Moral Event Horizon: Also some generic trolls speeches usually turn into hate speech which unlike the RUC or other trolls, ain't funny in the slightest and some go as far as threatening to kill Mike or the others.
Memetic Mutation: All the stream characters and some of the chat regulars. Quotes too.
Once Acceptable Targets: In 2013 or so when Bern was gaining relevance, Mike used her as the butt monkey for her gender identity. Nowadays he doesn't mind transgenders in the chat. Doesn't stop trolls from appearing though.
Propaganda Piece: The RUC wiki is considered this due to how over the top most of the stuff listed here is.
Trolls however like to make it seem like she is though which ironically, makes them The Scrappy.
Snark Bait: Lots of the games Mike plays, such as bad horror games, as mentioned above.
The RUC, due to making threats but never actually managing to do anything besides take credit for any technical issues the stream face, as well as everything written on their wiki.
Tearjerker: Despite Mikes streams being silly and fun, there have been some sad moments, both serious and silly.
Mc Whimples entire existence is this. A yellow devil man who is possibly suicidal, who has an abusive wife who'd beat him at any moment, and a Football team that is considered a joke among the Mutant League. No wonder why the guy has his Woobie status.
On a more serious note, the death of fellow chat user, Digital Adhesive counts as this. He was a good friend and youtube for Mike and suddenly he died of what Mike said, a heart condition he hid from the rest of everyone else out of fear they'd worry about him. Come the next stream, Mike was clearly mourning Digital and almost wanted to end the stream. He does get better though later on after finding a few games.
During the Undertale stream, Mike was on his fight against Undyne. Mike thought that weakening her would stop her. The chat was telling him to try and survive her onslaught of arrows until the heart turned red but he was too busy with the fight. Due to this though, he ended up accidentally killing her and as Undyne began to melt, the chat was panicing and Mike felt really bad and proceeded to redo the actual pacifist battle normally.
When Odyro decided to leave the streams, the chat ended up noticing he left and were missing him. Some users felt it was unusual not seeing him around anymore and Mike regretted the fact that he didn't talk to him more often. Even regular users who don't show much emotion would lament over him leaving.
Like Odyro, when Crystals 1986 decided to stop drawing images over the death of his friend Roger, this got Mike concerned over him, even if Crystals didn't know of Mike nor the fact that he was a silly joke among the streams. It got worse when people found out why Crystals stopped drawing.
They Copied It, So It Sucks!: Mike got hit by this in 2011-2012 when a certain big name Let's Player got very famous and despite Mike doing games like Ao Oni and LSD first, they think HE copied the Let's Player in question.
One comment in one of Mikes videos even thought Mike was a time traveler to explain this.
We're Still Relevant, Dammit!: As mentioned above, a variant of this trope applies to the RUC. Due to a combination of Mike streaming less(though he's gotten a new job now) and most of the other streamers moving to Hitbox, The RUC has been stuck trying to make themselves relevant since a majority of people lost care about the RUC to the point where they think they don't exist anymore(sometimes saying this the minute they pop up in chat). Though in a way, they're usually the most used material as an antagonistic side for fanart, fanfics, and fangames so they are kinda relevant there.
The Woobie: Mc Whimple. Poor guy can't catch a break and win a football game or get away from his abusive wife.
