The Elder Hydra, an existence which was far stronger than the other legendary rank beings, felt a sense of dread for the first time as Rudra suddenly released his full killing intent.
In the present moment, Rudra used the Dominator's Aura skill, which was exclusive to himself and brought out the terrifying auras of his own Dragon and Basilisk bloodline combined.
Compared to other subordinates including Omega who had Godbeast bloodlines, Rudra's was much more powerful and terrifying since others only had the bloodline from the descendant species and became variants of the said bloodlines. None of them were true Godbeast in the end.
In his case, Basilisks were one of the Godbeasts while Dragons were beings who stood above the godbeasts in the hierarchy of powerful species in this world, only below the Demi-Gods. Hence, his Dominator's Aura was the culmination of the best of the best.
