Although Evazan survived the blast and the subsequent fall , he squashed Rover in the drop , killing his loyal pet . Biography . At some point following the Battle of Yavin in 0 ABY , the male Meduza Rover came into the possession of Doctor Cornelius Evazan , who had taken up residence on Ando . Though Meduza were considered difficult to train , Evazan was able to tame Rover , using the creature as a bodyguard . Thought to be insane by many , Evazan was wanted in several systems for mutilating unsuspecting victims during routine surgeries in hopes of learning the secrets of immortality . During his time on Ando , multiple bounty hunters had attacked him , hoping to capture the doctor and collect the bounty on his head . However , all of the bounty hunters had failed , as the Meduza had helped to protect Evazan from these intruders , using his ability to produce an electrical current to subdue the would - be captors . After the bounty hunters were stunned or killed , Rover then devoured them . During one meeting with his benefactor , an Aqualish senator , Evazan was attacked by three intruders . However , he had been alerted to them by Rover , who had spotted the trio of assailants outside Evazan ' s castle home . Evazan and his assistant , Ponda Baba , each shot an intruder , while Rover touched the other from behind with the stalks on top of his head , electrocuting the man . The Meduza then proceeded to swallow the three dead men . However , Evazan was not safe . The Human bounty hunter Gurion Silizzar , who had waited outside while his partners infiltrated the castle , managed to make his way in and catch Evazan by surprise by using a holoshroud . Silizzar wanted revenge for the seven family members of his Evazan had killed and sought to bring the doctor to justice . Holding him at gunpoint , Silizzar took Evazan up to the castle ' s roof , where a starship piloted by the other two members of his team landed to take Evazan off - world to a planet where he would be tried for his crimes . Unbeknownst to Silizzar , Rover was following the two . While Evazan attempted to stall his captors when they reached the rooftop , Rover crept closer . Though Silizzar spotted the Meduza before it could engulf him , Rover was able to shock Silizzar ' s arm , causing him to drop his blaster . After a brief skirmish between Evazan and Silizzar , the doctor was able to throw Silizzar over the edge to his death . However , the senator — whose consciousness Evazan had mistakenly transferred into Ponda Baba ' s body in an experiment earlier in the evening — appeared on the roof , where he dropped a thermal detonator , preparing to kill the doctor for ruining his life as a senator . As Evazan screamed for help , his pet surrounded him , cushioning him from the blast . Though Evazan was protected by the Meduza in the subsequent fall , Rover himself was killed . The Meduza ' s final act had been one of sacrifice , saving his master at the expense of his own life . Personality and traits . Rover was highly loyal to his master , who in turn valued his pet ' s allegiance and protection . The Meduza saved his master from multiple bounty hunters and also protected Evazan from a thermal detonator explosion , though Rover was killed by the ensuing fall . Evazan was able to train Rover quite easily , despite the species ' reputation of being difficult to train . The doctor commented that one reason that the Meduza was so malleable was that he was supplied with a frequent diet of bodies , as a number of bounty hunters had attacked Evazan — and died in their attempts — during his time on Ando . The Meduza had a green , gelatinous body , and was covered in thin stalks that could produce an electrical current . Behind the scenes .

He later received a brief mention in both " The Essential Guide to Characters " and " The Complete Star Wars Encyclopedia " .
