The iPhone SE (Also known as the iPhone Stupid Edition) is King's second iPhone, he received it after he broke his iPhone 5s. It is currently his secondary camera.
It has the same appearance as the iPhone 5s, the only difference is that the back says SE and the Edges are Matte unlike the iPhone 5s.
The iPhone SE is shown to have a similar personality as the 5s as it got salty when King blamed Mario for killing Shy Guys in I HATE PAPER MARIO COLOR SPLASH. It is also shown to be smarter than King since he is the one controlling Mario.
The phone was bought by King to replace his old iPhone 5S that he broke. He currently uses it as a phone and his secondary camera.
