**Carl Wyvern** is a physicist researching parallel worlds at North Arkham University. His work centers on Black Points emerging after an outbreak event, particularly concentrated in Japan. These phenomena link the present to five distinct future worlds, enabling coexistence with beings called Z/X from those futures. Carl investigates the convergence of these worlds, theorizing that dominance by one world's influence risks collapsing the others and realizing that specific future. He observes that contact with advanced civilizations from these futures can trigger unforeseen phenomena, such as the "awakening of power" in individuals to counter threats.

Carl also explores an alternative outcome: if all five future worlds achieve peaceful coexistence, a hypothetical "6th future world" marked by extreme peace might emerge. This potential future hinges on choices made by key individuals identified as singularity points. Illustrating this peaceful scenario, Carl once playfully proposed a hypothetical situation involving a beauty contest among female-type Z/X. He worries this "worldly-tainted hypothesis" could compromise his dignity as a father if discovered by someone referred to as "L," indicating a personal relationship he seeks to protect. His research blends rigorous scientific analysis with occasional speculative and playful elements, reflecting a multifaceted approach to multidimensional threats and opportunities.

Carl Wyvern's dialogue includes the distinct phrase, "Too bad, it's me." He communicates in a style merging academic discourse with subtle humor, often followed by self-correction when his thoughts drift toward less serious subjects.
