Now someone mentioned that Joker from Batman was alike. That's completely untrue. Joker threw in jokes, and very sick ones, as he did even sicker things. Joker was *not* a comic relief. Every stupid think Joker ever did or said is morbid and freakish. As people say, clowns are funny in the circus, but there's nothing funny about a smiling clown by your doorstep at night. Joker has the bizarre-factor that Palawa Joko lacks completely. The Joker probably never faced an unexpected bad turn of events for his side, and his getaway schemes are always far more complex than running away through the sand at maximum speed.
Although Palawa Joko *might* have been like Joker, now he is certainly not. If that's due to lack of power in the present of lack of character depth, I don't know.
