Wow, I had no idea that Doryuuzu was such a midget. And it even appears to be bigger in the anime than in the games. I'd been picturing this thing as being the size of Infernape or Garchomp or something like that, so imagine my surprise to find out that it's only as big as Gible.
Maybe that's true in the games, but in the anime Gible is pretty short, it's barely "if bigger" than the size of Pikachu,
However in this episode Doryuuzu was definitely bigger.
