Meteor has revealed very little about his past, along with his history with Jonas and few other Marines. Meteor had a full manned crew before he became a Shichibukai, though his crew appears to have abandoned him for mysterious reasons by the time he goes to Guardna Island.
Free Arc 1
Meteor Luzi was seen on Guardna Island, answering a call from marines that requested his assistance, arriving a little bit after Spik did. Meteor wasn't really involved in Zone's plot, he might not even know now, due to Jonas attacking him. Jonas claimed that Meteor had slain his own brother, though the latter had no recollection of such a thing. The two briefly fought before they were interrupted by Jonas' LiuetenantGrace, who he killed. He left soon afterwards.
Free Arc 2
Meteor recieved a call on his way off of Guardna Island to head over to Skiathos Island. He met up with Kazu, who was at the docks, then used his devil's fruit to make a ship out of pumice rocks. Upon arrival, he met up with Commodore James, who requested that he take some prisoners to Impel Down. When Meteor asked why he would do such a thing, James threatened to blackmail him, forcing Meteor to reluctantly agree. James took him to where a deathmatch was being held between Makoto and Erza, and Meteor asked about the contestants and the rules before dropping in to interrupt the battle. He promptly dealt a killing blow to Erza, then told both Makoto and Johnny, who'd killed the observing marines, to meet him at the docks and brought them on board a stolen ship. Meteor then informed the two of them, as well as Kazu, who was on board the ship as well, that their next destination was Impel Down. He explained that they were going to break someone out, and when he was asked about who they were freeing, he told them that it was a former pirate known as the Tarot Master. He then led the crew to torture Zone in order to get him to convince the Marines to let them into Impel Down, before setting sail towards the undersea gaol.
