Flame Fu!

"Insolent child! You shall pay dearly for your disrespect! Still, to honor your Cooper ancestry, I will send you to your doom with the beauty of my new firework technique... Flame-Fu!"

- The Panda King to Sly, just before they fight

"Flame Fu!" was the final job and boss fight in "Fire in the Sky" of Sly Cooper and the Thievius Raccoonus.

Synopsis
Sly launched himself up to the Panda King's statue, where he engaged in battle with the Panda King. The Panda King insisted on making Sly pay for his disrespect by sending him to his doom, with the beauty of his new firework technique, Flame-Fu.

However, the panda was bested by the Cooper, and before passing out, the Panda King told Sly that his skill with his cane was unparalleled. Bentley informed Sly that he did a cross-analysis of the metal used in the "high tech blasting vehicle" they used in a recent mission and discovered that it could only be found in one place: the Krakarov Volcano in Russia. Bentley deduced that the volcano had to be where they could find the fifth and final member of the Fiendish Five, and urged Sly to find the pages of the Thievius Raccoonus the Panda King stole before fleeing the statue.

The Panda King on Ice
Sly received Otto van Cooper's pages from the Thievius Raccoonus, and used these pages to make technological advances to the van, which would come in handy for their next adventure. Carmelita missed her chance at busting Sly, but she managed to place the Panda King under arrest, thus putting an end to his destructive schemes and ensuring the safety of villages throughout the Kunlun Mountains. The gang took a break and visited Hong Kong, where they did a bit of shopping. They soon returned home to plan their next move.

Behind the Scenes
The Panda King uses the same introductory dialogue when this boss fight is recreated in the "King of Fire" mission in Sly 3: Honor Among Thieves, albeit with his lines re-recorded with proper grammar.
