You can barely see her, but that's Ferham in the bottom right corner of the center image. What's more, if I'm not mistaken, this is the first mention of Axl in RMO. It remains to be seen if he's actually playable so hopefully we'll get some more info on that shortly.
Furthermore, here's some new environment art and a closeup shot of Rockman Killers Punk and Enker in their RMO armor. These pieces were shown at the game's G-Star booth earlier, but now we've got them in much better quality:
The new trailer is set to debut online sometime tomorrow coinciding with new information about the game. G-Star is ever approaching so do look forward to future updates!
