apparently in the new episode poster, "Hungry Larry", it looks like Star is dressed like Ludo and Marco looks like an elf Goku... or is that just me?
Marco was a nerdy kid obsessed with Dragon Ball, in Daron’s first draft for the story (when she was still making her own comics), so yeah, he’s probably supposed to look like a generic anime martial artist. Elf.
And Star is Ludo… with a tail? Like Toffee’s one? It shouldn’t have spikes, though.
