Compared to kars ultimate life form he stood no chance if he were to try an fight and kill him hamon was rendered useless

Shikamaru is smarter than Otsutsukis, for me this is a feat that equals Batman Outsmarting gods.

The Otsutsuki ain't that smart though.

They are Aliens with Thousands of years with Huge Wisdom accumulated by the mileniums.

Awesome, name three complex inventions they've created.

You cannot Sum inteligence by Inventions, Kira is very inteligent and he never invented anything.

Riiiight, so can you show Shika outsmarting the Otsutsuki?

When did he outsmart an otsutsuki

He is able to deduce the plans of them, and what they want to do.

..So can you show Shika outsmarting an Otsutsuki, or..?
