READ FIRST:
All of these portraits are pure, png. files, and are not indexed. I am working on indexing the portraits while keeping their quality, but it will take some time. I apologize for this mess.
I have also started this thread over at the Smash Workshop, under the Customised Content sub-forum. I'll try to keep both threads up to date.
Not a very original idea, eh? Who cares? (Except for the person who might have made these already :'()
Over the next few years or so, (yep, FEW YEARS), I'm going to take 2D pictures of every character in the game and remake them into portraits. So far, not much progress has been made, but I need to start somewhere.
Some of these characters are tremendously difficult to find. For example, the Star Fox team was notoriously difficult for me to find until I found out that there was a comic book made with them, and I'm still missing Wolf O'Donnell. And I doubt anyone will find R.O.B, Pit, Snake (a clear picture of Snake, not the sketchy-ish versions), or even Donkey/Diddy Kong. If you want to help, try to locate some high quality 2D pictures of Brawl characters.
If you want to help, but can't use Google Image Search well, here are a couple of ideas of where to look for 2D pictures:
Box Art
Concept Art (Unlockable Features in-game?)
Manga
Comics
SSBB Stickers!
2D renders from 3D models
Fan Art (last resort only)
All of these files are png pictures, so you'll have to insert them into the common5.pac manually, with BrawlBox. If the picture looks terrible when you preview it in BrawlBox, click the "Recommend" button.
Please note any canonical mistakes or difficulties in inserting images.
Captain Falcon (The first Falcon is the true original, the second is my edit to the original)
Fox (Wish I had found a better uniform, this is his 64 appearance, not Assault)
Ike (bandana's unchanged, will fix later)
