Phantoms - they were the Citadel's main power, no, the only power that was able to resist the uncontrolled onslaught from the monsters.
Only they could kill strong monsters, in all its time, the Citadel could only find a way to defend against White and Green Threat Level Monsters, next to the walls using powerful cannons.
However, what was the main power of the Phantoms? Their abilities? Yes. Their physical strength and instincts? Yes. Their Nexuses? Yes. Their combat experience and Resonance? Also, yes.
The power of Phantoms was multifaceted, all Phantoms were different, but it all started with one thing, genes and physical enhancement.
Some weak White Threat Level monster couldn't even do much damage to a K3 or K4 Phantom, because it would be like an ant trying to bite through the thick skin of a hippo.
But, what about the Hybrid?
