Steve is a non-player character that has been used as a promotional character for Borderlands. His appearances have thus far been in the form of a Bandit Raider (or as a Psycho in Borderlands 3) and it is Steve who is the character who first used the now-iconic Borderlands catch cry, "Heyoo!"
- Steve first appeared as a stuntman and actor in Claptrap Web Series Episode 1, a behind-the-scenes 'filming' of Borderlands. During this sequence he is humorously called upon to "do something" about the bumbling, off-camera sound recordist.
- Steve's second appearance is actually in the game itself when he is heard in the The Zombie Island of Dr. Ned. Audio logs in this expansion indicate that he has been turned into a zombie.
- A trailer for Mad Moxxi's Underdome Riot shows a silhouette of a bandit accompanied by Steve's signature greeting, "Heyooo!" This addition is curious, given that Moxxi's second husband, Mr. Shank, appears as part of the story in the following DLC, and Steve is not a participant.
- The fourth appearance introduces a midget version of Steve as an enemy in The Secret Armory of General Knoxx named Mini Steve.
- There is a painting of a Claptrap in Claptrap's New Robot Revolution on top of a building to the left of the vice president of Hyperion. Within the picture there is a chat bubble in binary which translates to "Steve the Bandit."
- In Borderlands 2, Steve appears as an NPC during the "Clan Wars" mission chain. Speaking to him triggers his signature greeting. In this capacity he is stationed in both The Dust and The Holy Spirits.
- Steve appears as a background character in Tell Tale Games' Poker Night at the Inventory 2. He first appears in the opening cutscene arriving with Claptrap, and can occasionally be heard shouting "Hey-oooh!" in the background. Occasionally when the player wins a hand, Claptrap says "Even Steve could have won with those cards, and all he can say is 'hey-ooh'!", followed by Steve responding with his catchphrase, and Claptrap snapping back at him, telling him to "shut the @#$% up". In the Borderlands setting, Steve will fire a rocket launcher (with a fake confetti-producing rocket) at eliminated players. Ash Williams is knocked off his chair but survives. Brock Sampson shrugs off the blast and, with an irritated expression, chases Steve with a bowie knife. Steve is reluctant to fire on Claptrap, but does so with a depressed "hey-ooh" until Claptrap gets back up and tells him to "stop being such a drama bandit". For Sam, rather than firing at him, Steve simply startles him by tapping him on the shoulder and gesturing that he has to leave the table.
- Steve appears at the end of the trailer for the Lady Hammerlock the Baroness Pack, where he is singing the trailer's music in the Up Over Bar after Aurelia has frozen all of the guests. He then stops to see what is going on with the guests, to only to realize that they are all solid ice. The shock sends Steve recoiling in terror and falling out of the bar's window.
- In Three Horns - Valley there is writing on the roof of the Catch-a-Ride station at the Happy Pig that says "Steve The Lion Heart".
- Steve and his catch-cry are now frequently used as a comical reference among Borderlands players.
- Steve's best friend is revealed to be Jethro Shedd. Jethro is very upset when Steve dies in The Zombie Island of Dr. Ned, and is killed by him in turn when Steve rises as a zombie (Jethro thinks that his friend merely "wants a hug"). Steve returns to normal in subsequent appearances after The Zombie Island of Dr. Ned storyline.
- In the Claptrap Web Series, Episode #3, spoken dialogue reveals Steve to speak with a British accent.
- In the Claptrap Web Series, Episode #3, CL4P-TP claims that Steve has eighteen children.
- His weapon of choice appears to be an incendiary Machine Pistol, which actually shares sounds with revolvers.
- Steve has only been noted to say something other than 'Heyoo!' in the third episode of Claptrap web series to which he explains what he was trying to reference before possibly shooting Claptrap.
- Steve's catchphrase is a reference to one of the many iconic lines from Ed McMahon, a comedian and long-time sidekick of Tonight Show host Johnny Carson.
- Steve is either a member of the Zaford clan or working for them, since he is first met in The Holy Spirits and later on, Mick Zaford refers to him as "his man". In both encounters, he will respond with his signature "Heyoo" greeting.
- Joshua Davidson voices as Steve in the Lady Baroness launch trailer.
