Lord Downy would be offended if he had any thoughts of other people at all.
I do not think Downy could take down four elephants, imaginary readers. In fact, I find it highly unlikely. I think it’s been pretty well established that he can’t even take down four tadpoles.
Maybe if they were tadpole sized elephants.
Would you rather fight four tadpole sized elephants or one elephant sized tadpole?
The benefit to fighting one elephant-sized tadpole: it loses the sneakiness advantage of a ninja.
