According to Imperial databanks, Guardsman Lassicar was born to slave parents in the conquered system of Begeren. He gained the Empire's attention when he personally executed his parents and exposed their terrorist cell to Moff Harvus. Lassicar's subsequent rise through the ranks of the Imperial Guard is the fastest on record.
He has personally executed six Jedi and over two dozen Sith Lords who made the fatal mistake of crossing the Emperor. A team of SIS agents sent to assassinate him returned to Coruscant in a series of small containers. Lassicar's survival instincts and combat skills should not be underestimated.
