Was my first thought when seeing Gunnr today too! So we've still got the Bear and possibly the red demon/banshee to look forward too? She doesn't quite match up with the warrior Derby Demon or Banshee designs, although it's possible she was an early version before they split into two different characters? Think I've seen her in some other artwork before... let me try find it...
Oh hey, that one also has Gunnr!
