Artifact Title: That could be argued due to tendencies from the Fighters to go to locations other than the Mall or do things other than fights.
Ascended Extra: Fighters who, when first appearing, are unimportant, but then become more prominent later on. Diablo fills this bill, only appearing on Mall Fight 3 as a random drunk ranting about the lack of VODKA but then becoming a recurring villain in 4 and on.
Aerith and Bob: Tox, Waffles, Ran, Salt, Miniman, Paddy and Knife next to... Connor.
Bilingual Bonus: Due to Google Translate's accessibility, hundreds of messages on the threads are in different languages.
Bizarrchitecture: Word of Tox says that the Mall is infinite but with an edge. By that, he means that there is a central area and an edge while everything in-between is somehow infinite, which means that you could only reach the edge of the Mall through by-passing the infinite middle part.
The same goes for the sub-basements. You can only reach the bottom through unconventional means or plot convenience.
The city of Tox (which definitely came before the actual Tox) turning out to be a real place in Corsica. Even more coincidentally, Corsica is a French island; Tox and his Writer are French. The city came first, too.
The Gods: Godhead Fridge, Adrien Brody and Professor Brian Cox.
The Higher Powers: Martin, Backroom Six and Alexander the Great/Ultimate. They are all dead, though.
The old Mall Fighters (Claymorez, Aitruis, etc.)
The Mall Fighters themselves. A large number of their enemies want to take over the Mall to help take over/destroy the Omniverse.
Hammer Space: There's a reason why a Mall Fighter can carry 2 shotguns, 6 chainsaws, 2 swiss army knifes, 1 minigun, 591 copies of the Mall Fight Magazine, 692571 scrolls...
Lampshaded after Tox and Waffles defeated an army of Dutch people and obtained an unquantifiable number of mattresses.
Hearing Voices: Diablo hears Nega Ninja Medic in his head. How the Nega is doing this exactly, is unknown, but telepathy is unlikely, considering that the voice started showing up after Diablo was sent to the future.
For a while in Mall Fight 2, Tox had the spirits of Xot, Futox, Female Sam G, Code Monkey, Martin and Jim inside his body, and had to constantly hear their voices until he summoned them out.
Waffles has stated there are at least five people in his head.
Heel-Face Turn: Played straight with Diablo and subverted with Nega Tox.
Heroic Spirit: Most of the Mall Fighters have this at some point.
Home Base: Mall Fight Offices. Connor and Diablo both had their own personal version they call a lair, but Connor's is just a IT department with a bed, while Diablo's was a more traditional Supervillain Lair (When they don't get destroyed).
Kill 'em All: When it became clear that Mall Fight 8 wouldn't work, Connor and Tox' Writers decided to destroy the entire omniverse.
Loads and Loads of Characters: Although there are already quite a lot of characters who have been at least partly developped, Martin implied onced that there is an infinity of counterparts of just about everyone.
Even said counterparts have counterparts who have counterparts who have counterparts who have counterparts who have counterparts who have counterparts who have counterparts who have counterparts who have counterparts who have counterparts who have counterparts, etc.
Enough so that Nega Tox and Toxter were out-gambitting each other in Mall Fight 4.
Overly Long Name: The Timothy Bartholomew Gonzales Lloyd Martin Olive Kenneth Blair Herman family.
Plot Hole: Mall Fight is filled with fucktons of them (due to most of the story going on being purely improvised), but the biggest one is Martin and Backroom Six going back in time in Mall Fight 2 to "help" the Mall Fighters defeat Sister even thought Sister was still defeated in the future before they went back in time.
This results in just about fucking up the entire time-line.
An ironic follow-up of this plot hole is Futox asking Martin why he went back in time to defeat Sister even thought she was defeated anyways, even though he was never told that Sister would be defeated even without Martin and Backroom Six' intervention.
The most ironic thing is that Martin and Backroom Six did absolutely nothing when the Mall Fighters started fighting Sister.
Portal Network: The Hypercube System is basically that, in which you can go anywhere in the various universes and timelines by using the Cubes as a tele-transportation system.
Plot Parallel: Often used by the Mall Fight Writers to give a meaning to things that happened long ago but don't make sense.
Readings Are Off the Scale: By the time Martin was introduced, the notion of levels was completely distorted into oblivion up to the point where the Mall Fighters' levels were so high they stopped giving a shit about it. So, more often than not, the levels get reverted back to 1. It didn't help that Tox accidentally raised the level cap to 1,000,000.
Ironically, the level system is supposed to be a joke.
The Power of Rock: More prevalently in MF 2, where Ran used a Gibson Super 400 (it had many abilities, including creating a black hole), and in MF 7, where John caused all sorts of mayhem by using a Red Special.
