Gigantic

The first thing Kyle saw was how a gigantic head squeezed itself through the portal's blue liquid. 

His first reaction was to attack it before it would be able to pass through the portal. 

But, it looked like Kyle was unable to move. 

He felt as if he had been paralyzed for a minute. 

It was only then that he realized that death aura was leaking from the undead. 

Kyle bit his lower lip as he waited for his body to adjust to the sudden increase of the death aura that filled the entire entrance hall. 

This was easier said than done because the death aura was something he had sensed for the first time in more than a month. 

Even if the Skeletons and Ghouls were undead, they weren't a lethal threat to him. 

Furthermore, they had never been formidable existences, even before turning into Undeads. 

Unfortunately, the same didn't apply to the gigantic being that had now fully emerged from the portal.
