Who will he alter first ?

Your Best Friend

You picked up your phone and quickly dialed your best friend, Richard, he picked up after 5 seconds. "Who is it?" "It's me John, Richard, I got something cool I wanna show you." "Alright sure, wanna meet up at the park closest to your house in 30 minutes? "Sure."

You hung up, and took a shower, you were excited to use this power with your best friend. Richard was a kid of Indian descent, he was 2 inches short than you, and was thin as a twig with black hair. You two could become anything, from sexual gods, to kings, to robots. The ideas were endless.

30 Minutes Later, you were there at the park, Richard was already there, scrolling through his phone. "Yo Richard! Come here, I wanna show you what I got." Richard walked up to you, looking interested "What is it? But if it's a prank I swear to god."

You thought about changing him first, but what did you change about him?
