Early Life
Like most Pirates, Leon began as an ordinary Pirate. He sailed the seas in search of adventure, doing quests, killing monsters, and everything that a Pirate would do.
Becoming a Pirate Lord
Leon docked at Tortuga one day, after plundering some ships. He came across a fellow named Clint, who eventually recruited him, for he was a wanted man during a War. This War was no ordinary War, it was a War among Pirates, unlike any other. Leon loves adventure, and this was just the adventure he had always wanted, and so, Clint made Leon a Pirate Lord, along with Jack Sharkskull, and Luis Shipsilver.
Wolf Badfox
Leon Fireskull and Wolf Badfox were rivals, whom also trusted each other at times. Leon met Wolf Badfox at Raven's Cove, as he was searching for intel about the enemy, Edward Bladeskull, during his time as a Pirate Lord. Leon and Wolf were rivals for quite some time, but as the War raged on, Leon had no choice but to ask Wolf if he knew anything about Edward. Wolf gave Leon advice, which remains a mystery to this day.
The End of the Pirate Lords
Leon was in Padres Del Fuego, and Lilly was there, the girl who had betrayed Clint. Lilly knew what Edward was doing was wrong, and she told Leon horrible news. Clint and Jack had left Tortuga to Raven's Cove to meet Wolf Badfox, who they knew Leon trusts. However, this was not the case. Yes, Clint and Jack thought they were meeting Wolf Badfox, but Lilly told Leon that Wolf was captured, and was forced to bring Clint and Jack to Raven's Cove. She also told Leon that Luis had betrayed them all, and Leon already knew he was too late.
The Death of the Pirate King
The next day, Leon had recieved news that Clint had died to Edward. Without a Leader, Leon didn't know what to do. Leon had retired as a Pirate Lord, and was never seen again. It is said, that he will return when the Caribbean needs the Pirate Lords once again.
