Mole Miner Max is the boss of the fourth world Cave in the game Donkey Kong Country Returns and Donkey Kong Country Returns 3D. He is possessed by Banjo and fights Donkey Kong and Diddy Kong on his own train. When Max loses the battle, his further fate is unknown. (It could be possible that he fell off the cliff).
Max's train is a small, red one, with a big drill in front, and 5 carriages used for storing the stolen bananas. Max, himself, is a mole of giant size (twice as big as the other Moles), clearly making him the leader of the moles. He wears a hardhat like all the other moles and wears a miner's vest. Like the other moles, he throws pickaxes at Donkey Kong and Diddy Kong to try and hurt them.
