Nautiloid
Occasionally a design would work on its own but not quite fit the required stats - this guy looked too small compared to the final concept. But if we had ever needed a mini-nautiloid we had this version in the back pocket!
In development a unit would be designed stats/rolewise before we got to art, and often given a relatively generic name that matched it's role in game. But often this changed once art settled on a direction, and this was a good example of that - was the Ranger, but once this was designed we knew it needed a catchier and more evocative name.
