Rubybrood Zergs are different be certain stats and design affiliation with blood from other Zerg Broods, as highest floor of their volcano-like Hive is filled with blood.

Like Lora/Laura the Saber Of Blood, the founder of the Rubybrood, Queens are designed by adaptation with genome of scorpions. The Queens also adaptated with spiderwasps genome, enabling them to inject parasitic larvas into a targets, providing larger population of Rubybrood Zergs in exchange for lowering enemy force by killing from within.
