Five Hargreevess.

The other one had aftereffects from that drink... Dizziness and nausea, suddenly he was teleported to an unknown underground metro station... Entering the empty train car, he traveled to different stations, realizing they were timelines with different versions of his present.

As he cautiously advanced along the path, something suddenly emerged from the bushes—a silhouette, awakening Five's survival and defense instincts...

Pointing the weapon, he slowly and menacingly approached, he wouldn't let anything pass beyond the limits of his property...
