Battle For Your Life

Four gets corrupted by the darkness and becomes an overwhelmingly powerful threat

The Darkness; The Darkness is a giant, black, slimy, liquid-like mass of "pixelated darkness" that moves and flows like a sludge or shadow. The entity is surrounded by—and partially made of—glitching, colorful pixels that move at high speeds. It also has the 😃 emoji [no its victims don't get emojis] and its victims become mindless.

The Darkness amplifies it's victims power and strength in a dark and twisted way, and amplifies it's victims core traits. Four, being infected, had his protectiveness for his co-host X and his possessiveness to keep his contestants were amplified thousandfold, and his power and strength were amplified to an overwhelming degree, and his hatred for Two had been amplified thousandfold, making him a multiversal threat.

It was supposed to be a normal day in BFB, but The Darkness quickly took over Four, amplifying Four's power and possessiveness to keep everyone with him forever, and especially his overprotectiveness for his co-host X.
