User blog:Withersoul/What would you add to RWBY?

What would you add to RWBY that you think would be cool? It can entirely fictional or from real life.(but no original characters) I would add the Crimson or the Corruption from Terraria.

(If you think this post should be removed please say so, oh and you can put in multiple things)

On a side note what do you think could change in RWBY to make it better (in your opinion of course) or to stir up trouble for the characters. Oh and this random comic again.
