El Jefe

El Jefe was a high-ranking mercenary commander who had managed to conquer many countries across the entire world, selling them to the highest bidder.
Being a military strategist of the highest rank, he once boasted that he was capable of conquering a country using only three blind mice armed with nothing more than plastic spoons.
El Jefe vanished into obscurity sometime after Interpol forces were closing in on his operation.

After doing so he was more than likely contacted and hired by Cyrille Le Paradox to take on the task of erasing Rioichi Cooper from history.
El Jefe is more than likely the fiend who poisoned the feudal era's shogun's sushi in order to frame Rioichi and have him thrown in jail.

Then at some point, El Jefe constructed a 1,000 ft statue of himself, showing he thinks highly of himself, and also stole Rioichi's cane, most likely using a time machine to travel back in time.
He imprisons Rioichi, who is then freed and helps the Cooper Gang overthrow El Jefe.

Before being defeated and taken to jail, El Jefe gives one of Rioichi's canes to Le Paradox, who escapes with his blimp.
At the end of the game, it is revealed that he was transferred to a South American prison, given a job rolling cigars, but forbidden to smoke them, much to his annoyance.

In the set up/introduction, Sly describes El Jefe as a ruthless and cunning military commander.
He also notes that his glory has caused El Jefe to develop a level of arrogance and cowardice when faced with an even battle.
This is evident during his battle with Sly, as despite boasts of his superiority over Sly, his constant retreats during the battle say otherwise.
