The project's founder was BPC, or Budget Player Cadet, who wanted a mod "So stupid it would work", and began the project out of boredom. No ability to code did not stop him from beginning this project and seeing people who would help him make this silly dream a reality. As the mod came further along, they saw how overpowered and fun the game was, and named the project Brawl Minus and gained its focus on making everything powerful. Its emphasis on Power was stronger than +'s, and its balance was up to a higher standard than Balanced Brawl's, saying "They balanced the roster to Diddy Kong's level. We balanced them to the level of Akuma from SSF2Turbo."
Older devs are TSON, who did a majority of the original coding, Kirk, who figured out things about the game no one else could and made crazy ideas like turning Bowser into a grappler a reality, Xyless, who is most well known for our old CSPs, and other great named such as MonkUnit, Standard Toaster, MasterLinkXX, Kwalkest, and Oro!?
As for the current team, I'll state each current player and what we do.
Aries Veira - Awesome animator who creates animations like it's absolutely nothing. If there are animation changes, it's likely he had a part in it.
Damien - Also known as Dirt or Bowser the Train, he was the project leader from 2.0-2.X, he took the reins of the project after BCP left and helped form what it is today. Actually only came back to the dev team just recently.
Glitch - One with technical skill and interesting conversational abilities, he is the man who manages the codesets for both Brawl Minus and Brawl Minus Zeus. Not only that, but he also created our current tumblr and made these forums, go Glitch! Also ported Zeus to America for the curious ones! A huge fan of posting fun links in the BR.
Kienamaru - Kien is one of Minus' main coders, and a huge Zelda fan. He's responsible for the MAX incarnation of every Zelda character outside of Ganon, and has also done various work on other characters such as Ike. Also a huge fan of canon, incorporating many ideas from a character's game to help up the awesome. Very likely to ask you what your name is.
Mech - Designer for Brawl Minus. His primary contributions are....Oh, I'm not able to say it yet, you're gonna have to wait to see what he's cooked up!
Numbuh214 - A great coder who pops in from time to time, and has always stuck with Minus no matter what. He's responsible for the current incarnations of Royal Rampage and the MODARN SANIC build. Loves discussing pogeymans.
Pin Clock - I'm the current project leader, maintaining development speed and progress of Minus, as well as keeping track of everyone's work. I came up with the ideas for MAX Jigglypuff, heavily pushed the beta update that introduced MAX Dedede and Samus at the same time, and am responsible for the creation of the Valentine's Update, resuming Minus after we thought we were finished. In addition, I will be creating the new CSPs for Minus 3.3. Watches shows about cute girls doing cute things.
Sammi Husky - A young eager coder who recently joined the team and learned how to code with the goal of making Minus better in mind. He's providing touches on plenty of characters for the 3.3 update. Loves the Lucario.
Thunduh-Moo - The leader and primary coder for Minus from 2.X.6, all throughout MAX's beta to its completion, his coding abilities are through the roof, and will put his all into something when he is determined to do so. Which is pretty frequently. He is responsible for MAX's existence, the creation of many character's current incarnations, and countless countless builds of Captain Olimar. If you wish to summon him, use the Moo call. MOOOOOO!
Tybis - Our stage man, who looks at every possible angle on how to make a stage better. Responsible for touching up many stages, the Minus version of Yoshi's Island Melee, the upcoming Lavender Town stage, and stages yet to come. (Handshake).
And there you have it, a rough profile of the Brawl Minus Teams from then and now. I hope this post was informative!
