Been wanting to do this pic for a long time. Before anyone else says it, it is directly inspired by that Bark Vs Knuckles panel from the comics.

Since creating Berg the Polar Bear I basically gave Lunas his own physical match if not superior that he can cut loose and go all out with his strength, and like any anime fan I always look at epic fight scenes for inspiration such as All Might Vs Nomu or Luffy Vs Rob Lucci. When I saw the panel in the 30th Anniversary Comic with Bark and Knuckles, I finally had a great reference image I could use to draw a scene like that. Months of Laziness later I finally got around to doing it!
