Linka refers to Boris as her favourite cousin, describing him as "charming" when Wheeler prompts a slight comparison.
In order to get further supply of the drug from Skumm, Boris hides some pills in Linka's food, prompting the Wind Planeteer to become addicted. As a result, Wheeler has very little sympathy for Boris in his final moments. Gi is more sympathetic, claiming Boris was not himself when he hurt Linka and that the drug made him do it.
Boris dies of a drug overdose (possibly hastened by loss of blood via wounds on his arms) on top of The Capitol in Washington DC.
Boris is a similar age to Linka, and shares her looks, with blond hair and blue eyes. In his first scene, he is wearing a red shirt and blue jeans, though he later on his shirt changes to black with the image of a skull wearing a party hat. He goes back to his red shirt before his final scenes. He also wears mirrored sunglasses in order to hide the symptoms of his drug addiction - his eyes turn a reddish-brown whenever he is feeling the effects of the drug.
He often appears dishevelled and tired, due to his addiction.
Boris: These drugs can make you happier than you've ever been in your life.
Linka: Drugs! Boris, have you lost your mind? (She attempts to wrestle the bag of bills from him.)
Boris: Give those back! (The bag tears and the pills disappear down a drain.) You stupid cow! I needed those!
Boris: I need more Bliss...
Skumm: Sorry, kid, but the price of Bliss has gone sky-high. This isn't even enough to buy one pill.
Boris: Please, give me some! I am in agony!
Skumm: Now that's the funny thing. When you're used to Bliss, anything else is real pain.
Boris: What if I bring you a ring? With fantastic powers? A ring that controls the wind itself?
Skumm: A ring? You mean you know one of those Planeteers?
Boris: My cousin Linka.
Skumm: Forget the ring! Bring me the girl and you can have enough Bliss to last you the rest of your life.
Boris: No! I love my cousin - I will never betray her to you.
Skumm: Then go ahead and suffer.
Linka: Boris! I was afraid you were in that Blissed-out mob.
Boris: I have seen now that Bliss is bad news, so I have stopped using it. Thank you for setting me straight.
Linka: You should never have used drugs in the first place. I am so glad you've stopped.
After handing Linka a blintz contaminated with Bliss:
Boris: Isn't that the best thing you ever ate?
