This article focuses on the interactions between Russell and every other main character he has interacted with.
Despite being a pirate and rarely being around other characters, Russell is generally a nice character who never gets in negative ordeals with anyone, except for the characters who are considered antagonistic.
Russell is good friends with Cuddles. Every time they interact with each other, it happens while they are with other characters. They are seen trick-or-treating in Remains to be Seen; they're seen on a trip with others on a ship in Snow Place to Go, and they played baseball together in Can't Stop Coffin.
- Main article: Russell-Giggles Relationship
Russell and Giggles have had many romantic experiences throughout the series. They started dating in Sea of Love and later went on more dates in recent episodes such as You're Kraken Me Up and Put Your Back Into It. They even held hands around the burning school in Class Act.
Just like Cuddles, Russell is not only good friends with Toothy, but all of their interactions together happen while with other characters. They're seen trick-or-treating in Remains to be Seen; they're seen on a trip in a ship in Snow Place to Go, and they played baseball together in Can't Stop Coffin.
- Main article: Lumpy-Russell Relationship
Russell and Lumpy are shown to be very close friends to each other. They both worked together to escape the inside of a whale in Get Whale Soon. They also went fishing together and worked together to find buried treasure in Sea What I Found. Russell enjoys a trip with Lumpy on a ship in Snow Place to Go. He is also in a band with him in In a Jam.
Russell and Handy might be friends. They were both in a band together in In a Jam; they're also seen together in Ipso Fatso, appear to be getting along. However, Handy was unconcerned by Russell's death and celebrated his own lucky survival.
They interacted in a play in Something Fishy and rode a roller coaster together in Double Whammy Part I. In Easy Comb, Easy Go Russell buys Cotton Candy from Sniffles. However it is unknown (but likely) whether these characters are friends or not.
So far, the closest thing to an interaction between Russell and Cub happened in Bottled Up Inside, when Russell is shocked after he killed Cub.
Russell enjoys a trip on a ship with her in Snow Place to Go. However, he for some reason, is okay with forcing Flaky to get the can of beans from Giggles' rotting body.
Russell doesn't interact with The Mole that much, but seems to respect him as a blind person, as seen in A Sight for Sore Eyes; where he apologizes to The Mole for bumping into him and helps him up.
Russell and Disco Bear seem to be friends. They rode in the same cart on a roller coaster in The Wrong Side of the Tracks.
Like other characters, Russell dislikes the duo. They stole his buried treasure in Sea What I Found.
They don't interact that much, but have in a few episodes. Russell is angry at Mime in Mime to Five for killing his customers and fires him. In See What Develops, he has fun with the balloon sword that Mime made for him. He appears to be on somewhat good terms with Mime in Something Fishy.
Russell appears to be friends with Cro-Marmot. They both have fun with their balloons in See What Develops; they play baseball together in Can't Stop Coffin, and join a swimming competition in By The Seat Of Your Pants.
While not having properly interacted, Russell is most likely enemies with Flippy. He is run over by Flippy in Remains to be Seen and presumably runs away when Flippy flips out in By The Seat Of Your Pants.
He appears to be a fan of Splendid as seen in Wrath of Con; he was one of the few characters waiting in line to get an autograph from him.
