Steve is an expert crafter, and signs on to help Garrett and his comrades through the Overworld. He is played by Jack Black, who you will know from his extensive comedy career, including the “Jumanji” movies, “Shallow Hal,” “School of Rock” and more.

Steve was the original human discoverer of the Overworld, or the cubic universe like that of the Minecraft video game. He tamed his beloved dog Dennis with the bone of a dead skeleton and left the Orb of Dominance behind on Earth for Garrett (Jason Momoa) to discover and Henry (Sebastian Hansen) to put together.
