Alex Hirsch should get an honorable mention for voicing half the characters

The voice actors in this list had to have appeared in max. 3 episodes.

[@juliansenfr]

Maybe that's why Alex and Justin Roiland are best buds, they have a very specific idea on how certain characters should be & nobody could portray it the exact way they wanted it. So they did em all themselves.

It goes to show how first impressions change over time. For me, when Gravity Falls first came out, I didn't think I'd like it so much. But the more I uncovered of it, the more my admiration for it grew. To the point it became a contender for my favourite cartoon of the 2010s decade.
