Base of Operations
Reiji Nogi, known by his victims and simply as the Cassis Worm, stared at the display in front of him. The map showed large red Xs surrounding a structure in the middle. The Worms higher-up were panicking and expedited his transport from the front lines back east. 'Weaklings...' he thought.
Previously, his objective was to thin out civilian numbers while also countering the efforts of the so-called Neo-ZECT. Reiji was recommended to ease up on ZECT, but he paid no mind. He knew about the long-term plan, so as long as he didn't attack the main ZECT facility, the leaders were willing to brush it under the rug. Reiji had just finished executing an entire squadron of human snipers when he got the call.
Much like the others, he dismissed the early claims of the threat. The worms that died were simply weak if one human was too much. It was too bad that he couldn't feed. However, as the body count began to rise, so did his interest. He crossed his arms. ZECT would be implementing 'their' plan soon, and he wanted to see this new threat for himself before the extinction began. He had crossed paths with the one known as the Caucasus a few times. They shared a similar philosophy of strength. He did not care for humanity, just like his fellow worms. Power was what mattered. Unfortunately, he was ordered to keep his blade against him. They were on the same side, if only loosely. Reiji could not test his power and speed against him.
Suddenly, the room darkened, and a red alarm blared. Low-rank Worms around the meteor complex went into a frenzy to find shelter or escape.
"We're under attack!"
"It's here!"
"We're all gonna die!"
Meanwhile, Reiji simply smirked. More worms would come after the ZECTs mission. He could feed now before the fight and simply say that this Worm Slayer got to them first.
The Field Commander turned to a Worm in the same room who was sweating in fear at the security footage outside. An entire garrison had been eviscerated before his eyes. Then, he heard a loud crunch and felt a sharp pain. Slowly looking down, the lone worm saw the hand of his superior run through him.
Outside
When the Slayer first arrived, he wasn't surprised to see that the remains of the meteor had been excavated into a makeshift base.
After evaluating the area, there were several options for him. However, more information regarding the Worm invasion is needed. They are likely spread all across the planet. It would be more entertaining if he opted for the simple route of bringing down the Lifeforce Max Atlan and turning the place into a new smoldering crater. Still, any information regarding their forces would be lost.
Step One: Collect the information for VEGA.
Step Two: Glass the place.
Deciding on an angle of approach, the Slayer pumped his shotgun and restarted his pest control.
Meanwhile
Japan
Atop a building, the space distorted, appearing like a silver curtain. A brunette dressed in a black suit with a very light magenta shirt stepped through in seconds. The camera hanging around his neck and a large belt-like device shared the same color scheme. He glanced around before new information flowed into his head. "Interesting, another branch from Kabuto, but something feels off. Time to see if this world should be destroyed or not."
Ground Zero Base
The Doom Slayer trudged through the darkness. The facility's lights had gone dark. Presumably, they thought they could inhibit his vision. They thought wrong. Suddenly, the ground began to shake, and a horde of Salis Worms emerged from the shadows. All at once, they molted into their enhanced forms and clocked up, converging on the lone warrior. To them, the world stilled. Sadly for them, speed was relative for those on the same or higher tachyon frequency.
