CARTOON ANIMATION

Hello
I create 2D cartoon style animation using TOON BOOM software.
We have an Occuls Rift system and I want to take my characters into VR world.
I have no idea what software to use to create the characters and import them into Unity.
Also any Animation add ons Unity might have to make the Animation.
Thanks
Andrew

Export from Toon Boom into something Unity can use, like a sprite sheet.

thanks LaneFox for the reply and assistance. I’m very new to all this. Is Unity used ONLY for creating games ? My idea is to create my cartoon style characters in VR using Quill or similar and then making an animation cartoon , not a game.
Is this possible in Unity please ? Can you recommend any other character creation software please ?
