I think you're thinking of the shalrath model. The wizard model is alomost exactly the the one in the final version of Quake, except with a 'cleaner' skin (though it's messed up on one side and with a dozen more animation frames (some weird stretch out anim)
The shalrath on the other hand is mucho different from the one in game that we know and love, however it shares the same head as the final shalrath. However, the body kinda reminds me of Orko.
