Stranger tend to be perceptive and cryptic. He's concerned for Sunny's well being, and at the moment, hates Aubrey, Hero and the Hooligang for being the reason why Sunny is closing himself back in HEADSPACE with Omori. He seems to like however Kel and Basil, as they are supportive of Sunny. Stranger can create a bunch of tentacles that he uses to attack, and he's extremely strong and powerful, unlike Basil, who he takes the form of, probably for the fact that he's Sunny's best friend.
