So, based on this, there's no way to know whether the name "Megazoid" was even intended, in the end. By the way, scene 137B would have occurred after Valeris was taken into custody, on the bridge at the start of her interrogation. The scenes you refer to, Therin, are numbered 107 and 108 in that Fifth Draft.
We've had this discussion before, in relation to the unnamed copper-skinned aliens in Journey to Babel, but this case here appears to be more of a stretch than that, all just for Memory Alpha to have a name assigned to something unnamed.
