Noob needs no explanation, he's the Roblox Noob.
Mr. Bling Bling is who I want to use to represent old school tycoon games, since I can't find one good enough to get a character from but it's important to Roblox history. So he'd be able to place Droppers, gain money, upgrade himself mid battle, etc.
Despacito Spider is a new character, but they cemented itself in Roblox History by now, plus they are one of the few characters I could find that wasn't a humanoid shape so I had to nab it.
So bit of a history lesson, Knights of Redcliff and Korblox's Empire were two battle groups that were insanely popular in old days and even got official items from Roblox. When doing a bit of research I knew I wanted to have them be able to fight in the game, and I went with Redcliff Elite Commander and Korblox Deathspeaker because I think they are the most popular forms of their army. Redcliff Elite Commander playstyle wise I feel would be similar to Link but without his items (aside from sword and shield), and Korblox Deathspeaker would be a mage.
John Doe was a test account from Roblox that became a myth, and as such he's very scary and will definitely delete your Roblox account by [random date]. I thought it'd be cool to have a rumor character like this, and as such John Doe would the fictionalized version where he uses dark magic and glitch effects, along with other scary things.
Mr. Robot, I forgot why I put him here tbh.
Builderman is the second character I don't feel like explaining, but he's an alt account of a dev and is representative of building games is Roblox, and as such he'd be a Block Builder like Kragg and Steve.
Bacon Hair, because funny hair
Work At A Pizza Place is an icon to Roblox, and being served by a delivery boy is funny.
Don't like MeepCity but it was one of the first games to get a billion visits, plus Meep isn't a humanoid character so I nabbed it.
Adopt Me! is too popular to ignore, Anna is an NPC that I imagine would fight with pets and baby supplies.
Commander is a troop is Tower Defense Simulator, I imagine he'd have the ability to place down units and upgrade himself.
Arsenal is extremely popular and so are FPS games, Delinquent is a default skin
The Stalker is mainly just a character I wanted, loved playing The Stalker. It's also fairly popular and an old-school game (being from 2010) and I thought having more monsters would be cool.
Jake is from Loomian Legacy, I picked him out of all the characters because he was also in Pokemon Brick Bronze (cancelled due to Cease and Desist) so he's kind of the rep of two well known Roblox games. He'd kind of be a Pokemon Trainer like character.
Todd The Turnip and Beebo were both characters I thought would be way too fun to ignore, plus their games are well liked
Picked a Hider from Blox Hunt because I already knew I wanted Ethan and thought it'd be cool to have a Hider and a Seeker. Blox Hunt is a popular game that held multiple Roblox events so I thought it'd be justified. The Hider can turn into multiple items mid fight.
Ethan (Emma, Jake, and Sophia are alts) are from Hide and Seek Extreme, a very popular Roblox game. Ethan would have a mostly original moveset, but he still uses Glue.
Elemental User is from a fairly popular Roblox game, Elemental Battlegrounds, I picked them because I thought they'd be fun.
Ninja's moveset is mainly taken from Be a Parkour Ninja, a 2014 roblox game that's alright.
Black Bear is here because I feel I had to have a simulator character (not including Todd, that's a different type of Simulator), and I thought a Black Bear being able to use Bees and also being a Bear would be the most interesting fighter.
Murch is a merchant from Survive The Night, picked him because he has a huge amount of items,
look at this, it's insane. He'd be able to place traps, use shields, shot you, build a baracade, along with just a bunch of random junk
Piggy is from Piggy, a game I felt was too popular to ignore and I couldn't find any reasonable reason to not include. She'd be a heavyweight with a bat.
Robloxian is basically just Mii Fighters, but for Roblox avatars.
