A soldier-of-fortune and a high-stakes player, Lando Calrissian has long had a love-hate relationship with Han Solo. The suave Calrissian owned the Millennium Falcon before losing it to Han in a game of sabacc. But not long after, he won something of great value in another sabacc game: Bespin's Cloud City, where he took over as Baron Administrator.
Lando has proven surprisingly adept at running the Tibanna gas mining colony as a businessman. Lando's luck seems to run out with a visit by Darth Vader, who uses him against his will to spring a trap for Luke Skywalker. Vader entombs Solo in carbonite and hands him over to bounty hunter Boba Fett.
Finally convinced that the Empire will never leave his city alone, Calrissian orders the evacuation of Cloud City and fights back against Imperial forces, later helping to rescue a near-dead Skywalker from the very bottom of the floating city in the clouds.
Given the rank of General in the Alliance forces for past performance, especially at the Battle of Tanaab, Calrissian finally has a chance to fully redeem himself by piloting the Falcon for an a last-ditch assault against the second Death Star battle station in the Battle of Endor.
Here is the sound clip of Han saving Lando's life at the Sarlacc Pit in Episode vi.
