Starting from the absolute left and going clockwise:
Kagus the Human, with two Giant Eagle Groovesprites.
It is unfortunate there were no attribute controls. I was planning on giving Kagus and the Eagle Superior Musicality, which surely would have boosted their morale and combat prowess greatly.
All three are good martial artists.
Tarran the Dragon with attitude and a large knife.
Unfortunately DF does not have electric dragons or, for that matter, syringes. I abstracted as well as I could.
Flagrarus and his posse.
Pikachu is a hoary marmot with exceptional dodging skills, although in retrospect a fire imp may have been a more accurate choice.
Scyther is an antman with an iron breast plate and two longswords.
Ghastly is a slugman because, hey, what the hell. Slugmen are cool.
Moltres was intended to be a dragon, but an unfortunate error turned it into an elf of some sort. My apologies.
On the other hand, Moltres would have been rather OP, so yeah.
Flagrarus's Gameswitch was not taken into account here, because I had no idea how to model it. Flagrarus does, however, have two crossbows, a dagger, and a bolt, although my neglecting to give him a quiver caused him to drop the bolts and the dagger. Still, Flagrarus has the advantage of numbers here.
Inteuniso, I'm afraid, has nothing special going for him. I mean, he's a pretty good observer, but...
yeah. On the bright side for him, I forgot to add +1 to his team, so he's allied with Flagrarus.
Ragnarok97071 has a katana, cow leather armor, a cow leather cape, a crossbow and bolts. However, he also dropped his bolts. Note to self: quivers.
Schilcote is a human. That's... essentially it. Some basic hitting skills.
HmH is pimping it out with a solid gold crossbow. Also, his small inventory means he's the only one who can actually use his bolts. That's a pretty solid advantage there.
RedWarrior0 I was unfortunately unable to give charisma or movement penalties. He is, though, a professional kicker, the best in the arena.
ReDeadEr, Rexfelum, Maxicaxi, and Paranatural II are all just garden variety humans. Their chances are... not so good.
