I like to work on the various art projects, mainly for myself, for when I have an art block. To aid my most recent art block I'm going to create a companion project to Zodiac Fighters. While that project was sort of set in your 'fighter' genre of games, this new one will focus on the aspect of RTS games.
Of course to showcase all the various units, I need actual characters. It would be so much easier for me to just make up generic characters just to show off the various uniforms and forms but I think it would be so much more interesting if I used other people's characters.
So here are the 12 Armies you have to choose from, and I've updated the descriptions on the 'strengths' of the armies.
Empire of Dragons (all robotic army) - specialize in converting the opposing army to their cause
Sisterhood of the Serpent (female only army) - specialize in immobilizing their enemies
Asylum Flock - specialize in converting the opposing army to their cause
The Equine Campaign - specialize in long range warfare
Bovine 9 - specialize in espionage and sabotaging the opposing army
Ape Corps - specialize in close combat warfare
Street Warren - specialize in strength in numbers (the more they have on the field, the better they fight)
House of Hounds - specialize in (the more they have on the field, the better they fight)
Spicy Wing Fleet - specialize in weapons and machinery
Stripe Guild - specialize in elite units (your army is stronger the less people you have on the field)
Vermin Plague - specialize in infecting the opposing army and detiorating enemy numbers quickly
Suinae Mercenaries - specialize in immobilizing their enemies
Simply give a reference of the characters you want to offer and what army you think they would suit. You can put forward as many characters as you like, just be aware I might not use them all. This project will take some time to develop so patience is a virtue!
