Despite the frequent Schedule Slip and relative infancy of his Superman 64 LP it counts as one solely for the reason that as of yet no complete playthrough of this game exists on the Internet (in fact, it's next to impossible to find ANY footage of the game past the infamous rings). This effort was enough to make the LP noticed by Kotaku.
In episode 5 of Superman 64, he demonstrates the option to reduce screen size to 20% of normal - and despite having only a 15" monitor which is already distorted by his video capture technology, proceeds to fly through the entire first section of rings without losing a single life.
And beating Game BoySuperman, in its entirety, faster than just one level of Superman 64.
This is less a testament to Jon's awesomeness than it is to Superman 64's awfulness.
Uploading before Chuggaaconroy counts as one. Even Chugga noted this in his Facebook post.
Chugga: Jon uploaded before me? IT REALLY IS THE END OF THE WORLD!
When he fights the Ark Reactor with Jirard (after first being demolished by Hammer Force and continuing), the duo get to Runner Force and then Jirard gets cornered and finished off. ProtonJon, being stuck with flare (Fire and Force), has trouble dealing damage to him. Runner Force hits him while he's at 8 Vitality... bringing Jon down to exactly 1 hit point. He immediately finishes off Runner Force.
This gets turned around at the final boss, Golden Silver, where Jon is the one that dies and Jirard's the one that kills the boss.
The Notte Luminosa finale. By this point, it's revealed that the Romhack creator who wanted someone to LP his game as a dying wish was actually not dying at all, and was lying. The way Jon handled the situation was very adult and tactful, and it would be tempting to just unload on the guy, but Jon didn't.
Jon and Jake play Resident Evil 5. In part 4, they're trying to shoot the driver of a truck about to run them over; twice, Jake gets killed. On the third attempt, he shoots the driver, gets run over by the truck...and comes out the other side without losing much health.
Jon: MOVE BACK YOU IDIOT!
Jake: (shoots the driver) Nope, cause I killed him. (gets run over by the truck and stands up) Problem? (starts shooting enemies casually)
Jon: (after a Stunned Silence) Are-wh-are you...okay, I guess you're okay, that's good. (Jake starts cracking up) I saw you get run over by a vehicle, and then come out the other side, so I was a little concerned!
Jon sniping an emblem from the other side of the map in part 14. On his first attempt.
In part 22, after using up all his rifle bullets shooting an emblem, Jon only has his handgun left to try and shoot at a distant enemy they need to take out for the plot to progress. He does it on his first shot.
Managing to defeat, rather than stall out Wesker and Jill also counts.
In the finale, Jon and Jake run out of ammo while fighting the Final Boss and so attempt to take him on with just a knife and a stun baton...and it actually works for a while until they get killed by one of his tornado attacks.
Jake stabbing the emblem across a pit in the DLC, after being sure that he couldn't reach. The ensuing cry was worthy of the Game Grumps, so much so that Jon obviously had to tone it down in editing.
In episode 33, after having a lot of trouble with being sniped at by a turret, Jake asks Jon to try and take it out with his rifle, and shows Jon where it is by spraying his machine gun vaguely in the direction. Jon sights in on it...only to find that Jake somehow managed to kill the turret guy with his machine gun spray from a distance.
Part 2 of Desperate Escape has Jon tackling a majini through a shack, shattering it on contact as said majini gets thrown off a cliff, complete with a football horn sound and the word "SACKED!!!"
Jon: THROUGH THE BUILDING!
Jake: That was pretty hot. I'm slightly more attracted to you now, Josh.
The entire part 2 of Desperate Escape consists of Jon and Jake performing tons of physical moves on the enemies like iron tackles, suplexes, hammerblows, etc. Some of the moves also resulted in Your Head Asplode.
In the Collab "A Tale of Four Idiots" Castle Crushers series, one of the other players teases Jon about having flashbacks to Battletoads. Jon replies by nonchalantly saying: "Ah, whatever, I got over my Battletoads flashbacks. I'm one with the Toad now."
Jon ends up playing a nightmarishly glitched version of Super Mario 3 on a Retron and decides to continue out of curiosity. As several commenters point out, he manages to play Mario 3 better when he can't see anything than many people can the normal game!
And then he beats the game!
During his livestreams, he gives an "egg" to anyone who subscribes to his stream, which involves paying him five dollars a month in exchange for some chat and stream priveleges, an egg icon next to their username, and getting a voice clip of Wesker saying "You will give me an egg!" played for them. Normally, people subscribe when funny stuff is happening a while into the stream, but in one stream, someone subscribed within two minutes of him starting. Cue the chat erupting briefly about "record egg time", and several other people following up with multiple subscriptions within the next fifteen minutes.
The ending of the last round of Payday 2 from Heist Night.
During Bomberman Act Zero Night Two, out of a total of 57 games spanning 10 sets, Jon manages to win 28 (just over half) of them. What was second place? Dan The Enigma with five. Even more awesome? Jon wins 9 sets of games in a row out of 10.
As seen near the start of the first stream of 2014, just as one of Chugga's fans once got Charles Martinet to give him a shout-out in his Mario voice at a convention, one of Jon's fans got Martinet to do the same to Jon...in his Waluigivoice.
The following Bomberman Night, Dan even proved his win wasn't just a fluke by successfully "defending his championship" against his final round opponent from the tournament, Raiden, his Foil, Jewker, and the "Wild Card" of the chat, Clay. Although, Jewker was drunk following the Bomberman Drinking Game.
Jewker: You have no faith in him [Dan]. Let's be honest.
Jon: No, I have faith in him. He won the tournament.
During his 2/22/14 stream, not only does he clear the Veni, Vidi, Vici jump in VVVVVV for the very first time, but he also manages to plow through the entire regular career of the Wii Punch-Out!!, beating Mr. Sandman on his first try.
In the 2/25/14 stream, Tim utterly dominates the games of Wheel Of Fortune, but nothing shines brighter than solving BACONLETTUCE & TOMATO, not only because he did it with minimal letters, but because he figured it out after guessing T and only kept guessing letters to get more money.
During the April 30th stream, Jon plays an old version of Need for Speed. Most of his commentary is remarking on how he can run over signs willy nilly, but not the fence; until he catches up the next car and nudges the car out of the way. But instead of sending it skidding to the side, the car just flies to the side so fast it vanishes. That alone isn't that comedic, until...:
One commenter in the chat even says that he wasn't watching the stream when Jon screamed that, leaving him really confused, but still laughing at the randomness.
On the 5/17/14 stream, the viewer count breaks 4000 at the start of Mario Party 6, the channel makes it to the front page of Twitch, and then breaks 5000 andis top 10 by the end of the stream. Keep in mind that this was on a Saturday night.
During the Iron Man of Gaming tournament at SGC 2014, Jon manages to stay in the top three throughout the whole tournament and finishing second overall.
Also the chat who flooded the ScrewAttack twitch chat with support making it almost solely consist of people supporting him
On the 8/18/2014 Bomberman Act Zero Tournament, Dan ends up winning the entire tournament AGAIN! Then immediately afterwards, not satisfied with his victory, Dan challenges Jon to match for his BAZ Championship ...which Jon curbstomps him in.
Despite the fact that he missed two red coins, Jon got an otherwise perfect score on Poochy ain't Stupid in one attempt, even narrowly avoiding death.
As for when he did complete the stage 100%, it was only on his second attempt, right after the other one.
