What is the strongest antipsychotic in the world?

I'm curious to know, what is the most potent antipsychotic medication currently available on the market? Are there any recent developments or breakthroughs in this field that have resulted in the creation of a more effective antipsychotic than what's currently being used? Could you elaborate on the mechanisms of action of this strongest antipsychotic and how it differs from other medications in its class? Additionally, what are the potential side effects and risks associated with its use, and who would typically be prescribed this medication?
