Well I decided to instill Zodiac Spirits into some of the warriors.

Dragon- Brenna Kae (spirit becomes one with host in body giving host larger wings and scale armor; weak against magic)

Snake- Zack Brackton (spirit resides inside the sword and is released through slashes of the blades biting upon contact to force openings for host; spirit is useless without a weapon to instill it into)

Horse- (horse spirit is summoned and allows the host to ride; a lance is also gained by host to use; spirit can be more easily seperated from host)

Sheep- Grace (the host is able to communicate telepathically and create dimensional holes allowing travel between worlds; lacks ability to compete in fierce combat)

Monkey- (host gains better reflexes allowing more dodging; a tail is grown which keeps the host balanced; the appearance of the host resembles that of a monkey when the spirit is released; the host is usually unable to maintain this form for long)

Rooster- Dan "Twix" Filonov (after fusing with the spirit the host gains the ability of flight and is able to emit sonic waves through their voice however the host lacks defense and close range combat)

Dog- Ricky Rosado (host becomes one with the host allowing for more peaked senses but the host is unable to sense other zodiac spirits; the host also gains a tail and dog ears)

Boar- (the second best of the spirits in terms of strength provides a good offense defense combination but lacks in terms of magic)

Rat- Nick "VOD" Eckstein (after becoming one the spirit allows the host to multiply into clones though only one is real it is used to deceive the enemy; strength and defense are lacking compared to some other hosts)

Ox- (highest ranking in terms of strength the ox spirit allows the host to basically become a one man army who's only weakness is speed)

Tiger- Pat "501" Rooney (the most balanced of the spirits the tiger allows for excellent adjustments in the host's skill but at the cost of personal injury when bonding has ended)

Rabbit- Loki (host gains higher speed and is able to attack quicker; lacks strength but the host is able to detect power levels of others more easily)

Though I don't have all the characters i have put a description of how each spirit works so you all know.
Good- Dog Dragon Snake Boar
Evil- Monkey Ox Horse Rabbit
Neutral- Sheep Rat Tiger Rooster
