Guzzu: "I was assigned to do the inbetween and animating the goons / enemies. The first passes (rough) were by my friends Spencer Wan and the trailer director, Eric Huang. The inbetween pass was by me, then beautifully finalized by Kay (Kaynimatic, twitter)."

Actually I only scribbled a bit on this while I was drinking. First pass was by Max Collins.
