Isabelle from Animal Crossing sits at the top of Zachary Levi's similarity graph at 0.83 — a fictional character outranking every human neighbor in the set. That's the structural signal this data leads with.

The shape is two-peak. The first peak clusters around Isabelle (0.83) and Alan Tudyk (0.80), with Felicia Day (0.77) close behind. The second, lower peak runs through Nerdist (0.75), Wil Wheaton (0.72), and Simu Liu (0.72). Together these two clusters define the audience's shape: one neighborhood anchored by a gaming-adjacent fictional character, the other by actors and media properties associated with genre fandom and geek culture. Subcategory breakdown across the top 10 confirms this: six of the ten neighbors are Actors, one is a Fictional Character, one is a Website, and two are Directors — James Gunn (0.72) and Kevin Smith (0.71). No TV Shows, Musicals, or Entertainment Platforms appear in the top 10, though Wicked the Musical (0.72) and MoviePass (0.72) sit just outside the tightest cluster. The dominant neighbor type is Actors, but the presence of Isabelle at the apex — above every human in the set — marks this audience as one that bridges live-action genre fandom with gaming and animated character culture.

The two-peak structure suggests Levi's audience doesn't consolidate around a single type; it spans a fandom-oriented actor cluster and a gaming-inflected pop-culture cluster simultaneously.
