That third eye of shiva won't do much good on the monkey king. If you remember correctly, that primate was supposed to get roasted with heaven's fire after he was captured. All it did was make him stronger and give him those fiery eye.
Hence, you can't beat monkey king with fire

Even if you send the legion of angels on him ( which I must emphasize is not allowed ), he took on heaven's army a couple of times already. And still he is up, running and ass whooping.
Hence, nameless, expendable, staff fodders won't count as much when up against this guy.
