For the first year+ after Shat first made it in game, it was fondly known as the Shattnerer by most of the early Gw2 writing and content teams. I'm pretty sure Darrin had pictures up on the wall around the office similar to the sweet sweet link from Bobby. Fun memories ;)
For additional trips down memory lane -> This was also the first ever giant boss built that made it into the game.
Though it wasn't actually the first giant boss model ever made, that distinction rests with the leviathan (a massive crazy huge sea creature boss that only ever showed in trailers) was the first ever giant boss model. Early in development after the model was built engineering shot it down as creatures that large in water were too expensive for performance and our engine couldn't support moving platforms (collision) in large open world maps.
