Just a passing through Master wrote: Mephistopheles is similar to Blackbeard but worse, he pretend to be fooling around, but no doubt, he is the dangerous one, even his bio warn you that you shouldn't trust him. (Irony that he never show his real capability yet.) Bonus point, Koyasu provide JP dub for Joker twice.

Joker actually death for real at least more than twice... but he just cheating his own death and comeback like nothing happen to him. I don't remember much since there will be retcons and the fact the DC Rebirth happened in 2016 (Yes it is a reboot as well given the elements of DC's New 52 series and its continuity has been incorporated) so those deaths may or may not count at all.
