Festivity Attenders
The first recorded group of people who were obsessed with going to parties but rarely ever did (unless you count History Goers), the Festivity Attenders were largely natives of Scotland in the mid 1500s (1530, to be exact). They bore STRIKING similarities to the Party Goers, though, as SteveT says:
"I hereby swear vengeance upon the Festivity Attenders and any organization that even remotely reminds me of them, regardless of whether the resemblence is actually there, because the Festivity Attenders were an original creation unlike any pre-existing groups of characters!"
The stories of the Festivity Attenders largely revolved around SteveT, as he was one of the few alive at that time and the present time (technically Masamune and Murasame were alive, though they don't appear), though the Donkeyman had wheedled his own backstory in as well.
The first OG (Festivity Attenders: The Metallic Menace) was written exclusively by SteveT, though the second (The Festivity Attenders: Deluge of the Doppelgangers) was planned to be a group OG. It was completed after some time, leading to the start of The Festivity Attenders: Revenge of the T.
The Festivity Attenders included:
Shakespearean Narrator: A parody of Narrator.
Elemental: A parody of Golem.
Louis LXIV: A parody of Luigi 64.
Ruby Red: A parody of Sapphire.
Wizzrobe: A parody of Magikoopa.
Dinosaur-Type Fellow: A parody of Yoshiman.
Sir Prophesy: A parody of Mr. Predict.
Albert the Large: A parody of Big Al.
Paddle: A parody of Flutter.
Mimic MacShifter: A parody of Ditto McCloaker.
Hrunting: A parody of Vorpal.
Excalibur: A parody of Masamune. Apparently he is actually Masamune and Murasame's father.
Louis of the Tubes: A parody of Luigi of the Pipes.
CHUMP-ANZEE: A parody of GORE-ILLA.
As well as Wrange Tirk and SteveT as themselves.
Also appearing is FOUL Alchemist Fellow, a parody of EVIL Scientist Dude.
In GMOG Holiday Special: Happy Father's Day, Masa! Excalibur mentions The Playwright (parody of The Director), another Festivity Attender that is never seen in the stories.
