This shark is a bit small technically for both 5e and Pathfinder purposes, but only because they both lack an intermediate size. Both D&D and Pathfinder have regular 'large' sharks, but the Monster Manual has the Giant Shark at 30ft, and the Bestiary has the Dire Shark at 60ft! Yikes.
In LEGO scale, this shark is about 17 feet long - a true terror, and probably sufficient as a Giant Shark or Dire Shark. We have no immediate plans to build a 60 ft Megalodon!
This is not manufactured by LEGO.
