The leader of assassins that kidnaps kids and turns them into his own species to join his team. o:

Well that sounds familiar somehow...

Anywho you are an NPC commander that shows up and kicks ass through various parts of the game as being pure awesome and perfect. But as you get stronger he loses some of that dazzle as you get closer to even terms and you see the very human man behind his reputation and his unfortunate part in the events that eventually led to your own quests to right his wrongs.

A generic enemy that are everywhere in a video game's afterlife/Hell/Hades-ish world.

The person possessed by the core of chaos, whether a devotee to chaos, or an innocent, it doesn't matter. You threaten the balance of the world, and must be destroyed.

The ice spirit that's actually the wandering ghost of a long-gone adventurer. His corpse lies at the bottom of a cursed frozen lake, and he helps the party greatly after they defeat the warlock who cursed the lake out of revenge and give the body a proper burial.

the tree alien summon that has teleporting wish granting powers like a genie.

The undead little girl who's been lost in the forest for centuries, and turns into a demonic monster when she finds out that the party isn't her mother.

A Christmas-themed wizard. :)

The Mad-Hatter's wife?

Blind healer/fighter

You would be the powerful oracle that the main character goes to for cryptic hints of what may come.

The companion that is more interesting than she looks. :)

In an open-world fantasy game, RinLin is a wandering faerie merchant that sells rare and magical items. At first, the prices of said items are far too steep for any normal player to find, but as you collect vials of faerie dust from dungeons and enemies, she takes it in exchange for discounts.

If you collect all 150 vials of dust throughout the game, she joins your party! In general, she is considered one of the best healer-mages in the game, but to get her you have to REALLY go exploring.

Eeek, how awesome :D

Key is a mysterious woman. No one knows of her origin, or how she ended up working for the richest family in the country. Some say she have hypnotic skills, and made use of those, but Key knows better - she's just living there due to a contract.
Help her get free, and this skilled alchemist/assassin will reward you handsomely.

In a cyberpunk game, Rin would be an orphan who lives in an abandoned alley, and takes care of all the stray animals at night while trying to make a living selling scrap metal handiwork during the day. The party first meets her while they're running away from a boss that's too strong for them (that they'll get to later), and she quietly directs them into her alley to hide, then distracts the boss while they escape.

Espsy is an unlock-able character that was once your enemy, but has found out they were used by the evil forces and have turned to get their revenge. Turns out to be the most loyal fighter in the whole group, but lacks healing skills.
Fighter/Ranger class.
