Mysterious .. + 7th Anniversary Video

I'm still trying to discover what's that monster on the left. Can't really define what's it.

They look like scarred bears from Arans quests.

Edit: I cropped and sharpened that image a bit and turned the monsters vertically. They seem to be upside down in the picture. Looks even more bears to me atleast.
Edit2: And that looks like a war machine the mapler is riding. Hitting the ground with tha machine, making monsters fly. Seems kinda, weird. But as stated before, pirate with machine would make sense with omega and such.
