Well let's see

1) Ghostly White-Mage/Healing Spirit. (Stuck with two spells without help, but a little can go a long way. White Mage already down, so no need to panic.)

2) Wraith / temporary bodysnatcher. (Hijack people's bodies and fight with them. [i]heart-stoppingly spooky.[/i])

3) Minotaur Lightning-Bruiser. (Huge, fast and strong. Mix in lightning symbol-magic for one hell of a charge.)

4) Minotaur Archer. (Imagine a walking siege ballista with horns. Bullseye.)

5) Paper-golem. (Recycled idea from an RP that folded. A walking, talking spellbook, potentially good for boosting magical abilities. Also shapeshifting!)

6) Quicksilver golem. (T-1000 on fantasy steroids. Really malleable concept.)

Edit:
7) Old Dryad. (Another healer-ish character, probably way more in tune with nature. Older than the trees, in this world and the otherworld.)


Each one has a few potential pre-reincarnation histories that will act as the character's driving force.
