Magnasaurs here are a higher form of Rubybrood Hydralisks, having a genetics of primal creatures, giving out some sort of velociraptor rush straight onto a battlefield.

Primalisks are not to be confused confused with Aquatic nor Primal Zergs, despite of their ability to fly, burrow and swim in same speed. Here, they are actually a higher form of Rubybrood Zerglings, becoming a sort of ultimate organisms that lead their lesser brethrens as a literal packs, like those of wolves.
