Ekko is not yet the champion we meet in League of Legends, but his look in the ARCANE series finale is a send-up of who he’ll later become.
“Ekko is a character that our fans love, but we knew he wouldn’t have all his abilities by the time of the finale,” Baudry explains. “We wanted to show the potential of the boy savior, the genius with the potential to defy time.”
Throughout ARCANE, Ekko wears his signature green and orange colors along with a white hourglass symbol painted on his head. Baudry notes that for his Episode 9 design, they wanted “to connect [Ekko] visually to Jinx,” so that both characters’ distinctive looks resonated with each other.
“The color palette of this costume of Ekko is mixed with Jinx’s color palette,” Baudry adds. “There are visual elements and graffiti that [call back to] their fight in Season One.”
