Easiest and Hardest Sly Cooper Bosses

My easiest boss was the Panda King in the first game and the hardest was the final boss in the third one. What was yours

Really Panda King for easiest ? None of the bosses are really hard, but the hardest for me was probably DR M (LAST BOSS FROM 3) or MZ Ruby from 1. Muggshot was pretty easy so was the frog from 1 and the pirate from 3. Those are the only ones I really remember.

WE NEED A SLY 4

Well all the bosses from the first one were easy,and I mean EASY. But Panda King was the easiest because he only has 3 attacks that he can use and it is the exact same thing over and over. And yes we NEED a Sly 4
