Luma created Korg’s excitable sidekick, Miek, in-house. The team shot high-energy punching, kicking, jumping and flipping in Luma's motion capture studio so that animators had a more specific type of motion to use in their shots.
Luma built and sculpted Biff from the ground up for his appearance in the Parade of Victors sequence. The team began with detailed concept art, which was then handed over to Character Supervisor Matheiu Aerni to run with the designs. He pulled reference from rhinoceros skin, lamprey eels and even from the elaborate costume design in Thor to achieve the look of the character. Biff is intended to give the audience a little jolt, so animators ensured that he felt weighty and imposing, his skin craggy and revolting and his roar freakishly terrifying.
