Trivia, insights & behind the scenes
The entire series exists because Cartoon Network wanted to age up the franchise for the original 2005 audience. The creators literally watched their fans grow up.
Gwen and Kevin's slow-burn romance basically defined 'enemies to lovers' for an entire generation of animation fans. The trope owes them money.
