El Jefe

During the events of Sly 4: Thieves in Time, a mercenary tiger called El Jefe appears as the main antagonist of the game's first past level set in Feudal Japan.

Sly 4: Thieves in Time
El Jefe first appears as his men have taken over Rioichi Cooper's sushi house and led to Rioichi being imprisoned for "tainted sushi". After Sly frees Rioichi, Bentley pulls up information regarding El Jefe, noting his past successes in bringing down governments for the highest bidder as well as evading the law. During the events of Sly 4, he works on behalf of Le Paradox in order to collect Rioichi's cane. Naturally, this puts him at odds with the Gang.

Towards the end of the level, El Jefe ambushes Rioichi and steals his cane, prompting Sly to give chase. El Jefe proves to be quite formidable due to his speed, swords, and element attacks. Nevertheless, Sly defeats the tiger, although he loses the cane to one of Le Paradox's goons. Following his defeat, El Jefe is finally arrrested for his crimes.

Attributes
El Jefe proves to be quite the formidable fighter as shown during his boss fight when he leaps over burning and spiked towers all while taunting Sly. The tiger has a massive ego, believing this to be a demonstration of his true strength and once being noted by Bentley as claiming that he could arrange for "three blind mice with spoons" to overturn a country. Despite his ego, El Jefe is a tough opponent until Sly deflects his fire attacks back at him, leaving El Jefe open for attack.

He is also a bit of a pervert, as he is shown slapping Murray on the butt while the hippo is disguised as a Geisha.

Given his appearance, cigar-smoking, and Spanish accent, El Jefe is an anthropomorphic tiger version of Fidel Castro. Even his title "El Jefe" was also a nickname for the former Cuban dictator.
