Big Mickey first speaks in the episode High Tide when he loads steel for the Z-Stacks and the Star Fleet. In the episode Munitions, he loads the naval tramper Kraka-Toa with explosives. Later, a fire causes his dock to collapse and he sinks (in the TV version, it is said he is saved by landing in shallow water).
Big Mickey is known to be supportive towards the Star Fleet, as he roots for them in their competition against the Z-Stacks for the steel contract and according to Zorran, he is clearly his own boss as he noted that: "Nobody tells Big Mickey what to do!"
