Although Atticus had crushed Eletantron's head and Ozeroth ripped out Jezenet's, paragons weren't so easy to kill.
They were cockroaches in human skin. The both of them had tricks up their sleeves, more so the Vampyros queen, Jezenet.
If Yorowin, the Vampyros grand elder whom Atticus had fought in the past, had been able to regenerate his entire body from a single drop of blood, their blood queen could easily do the same.
Her blood was all over the battlefield, and merely ripping off her head wasn't enough to kill her.
For Eletantron, while he couldn't use his space control to teleport away from Atticus, he could still use his powers internally.
However, trying to teleport his brain away from his head was nothing short of stupid, it would simply kill him.
Instead, he chose something else. Something smarter. He decided to replace his real body with his alternate self, thereby sending himself into the alternate dimension instead.
Both tricks were smart. Brilliant, in fact.
