How Old Is Killua Zoldyck In Steins Gate

It’s a fascinating question that sparks curiosity for fans of both anime, but let's clear up the biggest misconception right away: Killua Zoldyck, the beloved deuteragonist of Hunter x Hunter, does not appear in the Steins Gate universe. These two incredible anime series exist in completely separate narratives, each with their own distinct characters, worlds, and timelines.
So, if Killua isn't in Steins Gate, why does this question come up? Often, it stems from the expansive and interconnected world of anime fandom, where characters might cross over in fan fiction, video games, or even just our imaginations. This hub article will dive deep into Killua's actual background and age within his own series, explore the distinct universe of Steins Gate, and help you understand why this particular question is a common source of confusion.

Unpacking the Mix-Up: Two Worlds, No Crossover

The initial question about Killua Zoldyck's age in Steins Gate immediately highlights a common pitfall in the vast world of anime and manga: the accidental blending of distinct universes. While it's fun to imagine character crossovers, Killua Zoldyck is a character entirely exclusive to Yoshihiro Togashi's Hunter x Hunter. He belongs to a world of Nen abilities, dangerous Hunters, and intricate power systems, a stark contrast to the time-traveling, scientific thriller that defines Steins Gate.
Understanding the unique setting and premise of both series is key to unraveling this common confusion. If you're curious to understand the foundations of his world, we've prepared a comprehensive guide to the full [hunter_x_hunter_overview text="Hunter x Hunter overview"].
