Not a Navi like companion. Like someone who travels with you. BOTW was good but one thing I really wanted to do was travel with some people in such a lonely world. The next game you should be able to travel with a memeber who gives you advantages ( Zoras swim really fast, Ritos could fly you up a certain distance ). And you could upgrade them through armor and weapons. AI would have a dedicated button ( Up on the D-Pad ) and have a wheel on commands ( like follow me! or go there! ).
