Can someone explain to me how Darth Maul is alive? I don't watch the cartoons.
Maul was falling for a long time, but his fall is stopped by the Emperor, as he still needs his apprentice and does not have one in the wings yet.
in a real elaborate scene similar to the end of Episode III, the emperor stabilizes maul and gives him magical robot legs that allow him to transform into a mini spaceship like some sort of Transformer.
However, the loss of his legs and rage at ObiWan drives him mad, so he transforms into his spaceship form and leaves for another world, ending up on Corellia where he meets and falls in love with a young princess named Lychore.
They get married and he takes her name. Also to honor that he is now part Transformer, he takes T as his middle initial and is forever after known as :
Maul T Lychore.
And now you know the rest of the story.
