If LN show Tannin as a western dragon and described like this, with Grendel expressed as the first dragon that Issei saw walking with two legs, is obvious that anime make it wrong. Season 3 is full of mistakes comparing to the LN, the hand of the author is not so heavy, there are plenty examples of this.
