Little Penguins of Madagascar things

Which makes our first revelation… Danny Jacobs.  Known to Fanguins as “King Julian”  Danny Jacobs plays Victor Zsasz.

According to Wikipedia:

Origin story

In Batman Chronicles #3, told by Zsasz himself, it is learned that Victor Zsasz was the head of his own international company and had amassed a large personal fortune in addition to his family’s wealth. At the age of 25 his parents died in a boating accident, sending him into a deep depression. He turned to gambling, losing money in competitions around the world. One night, he ended up in a Gotham City casino, where he gambled everything he owned and ended up losing it all to the Penguin; afterwards he saw that his life was empty, driven by desire, and there was no point to his existence. While he was attempting to commit suicide by jumping from Gotham Bridge, a homeless man tried to assault him with a knife after he refused to give him money. Instinctively grabbing the knife, Zsasz saw in the man’s eyes that all life is meaningless and that nothing nor anyone matters. He then proceeded to stab the man to death as a “gift” for saving his life. From then on, he dedicated himself to “liberating” others from their pointless existence (Zsasz often refers to victims as “zombies”). He usually preys on young women, but has no qualms over whom he murders. He slits his victims’ throats and leaves them in lifelike poses, adding a tally mark to himself each time. He has been diagnosed as insane and is regularly incarcerated in Arkham Asylum courtesy of Batman, breaking out on occasion to carry on killing.

In addition: he appears as mini boss in Lego Batman 2.
