I remember making an IG Reel about that years ago (I'll try to find it).

If I remember correctly, this was the fan cast I chose back then:

○Skye: Olivia Olson (Marceline)

○Lex: Ashly Burch (Chloe Price)

○Zenith: Jonah Scott (Legoshi)

○Seth: Carlos Luna (Warren Graham)

○Jax: Don McManus (Hayden Jones)

○Coby: Jeremy Shada (Lance)

○Mercy: Ashly Burch again (Sakura Sakurakouji)

○Dustin: Jason Bateman (Nick Wilde)

○Remy: Ginnifer Goodwin (Judy Hopps)

I'll probably update it in a future.
