Dr. Hayashi examined his new specimens with a twisted sense of pride, yet impatience gnawed at him. Fifteen wasn't enough. He needed more—an army. Fifty, perhaps a hundred, regular zombies transformed into obedient specimens would be a solid foundation to begin expanding his control. Only with overwhelming numbers could he hope to capture one of the elusive Striders, or, if luck allowed, a Creeper.
Creepers, he reminded himself, were unlike the regular undead. They were quick, lurking in the shadows, emerging only at night and always in packs. Encountering one alone was rare, and a swarm of Creepers could take down a group of humans or specimens within moments. For Hayashi, capturing a Creeper was an ambition he couldn't yet afford. He needed more specimens first, enough to handle the brutal pack attacks of these nocturnal hunters.
