Adam: Works in garden furniture. Seems perfectly normal.
Alfred J. Pilbrook: Owner/manager of Arthur C. Clock's timepiece shop. A timid, aging gentleman.
Ali: Head of the power tools department.
Angela MacGregor: Head of the curtains and blinds department. Angela rarely impacts on the plot directly, but is often present when someone makes an uncharacteristically unpleasant or ruthless decision. Sister of Sadie MacGregor.
Axel Platzoff: a 'reformed' supervillain, formerly known as Professor Devastato. Axel has been channelling his villainous tendencies into the struggle against the DIY Barn. Archenemy of Captain Stellar, sometimes mentor to Norman and Fiona.
Belinda: An extremely annoying Pavilion staffmember. She changes departments frequently, presumably deliberately shuffled around by irate superiors.
Bruce: The ghost of one of the electrician. He was one of contractors who originally built the Handy Pavilion. Another contractor – a concreter – discovered that Bruce was sleeping with his wife, and buried him in the concrete. Bruce finds the afterlife somewhat unrewarding.
Buck Dusty: A cowboy who works in power tools. Buck reports to a mysterious organisation of mysterious western types known as COWBO. COWBO seems to report to something called the 'Grey Barn', though it is not clear if this is related to the DIY Barn.
Captain Pete: Sinister one-handed aquarium specialist at the Place O'Pets.
Captain Stellar: aka 'Vincent'. Superhero and member of the Vigilancers superhero team. Former archenemy of Axel Platoff. Boyfriend/former boyfriend of Cycloman
Carol: Owner/barrista at the Super Centre's only good source of coffee. A slightly annoying new-agey hipster type, Carol is also completely fearless. In love with Zorbar.

Laura Cho: A new employee who gains super powers when one of Axel's superweapons explodes. She becomes the superhero Voyager, and is vexed by the appearance of her own doppelganger from the future. In love with Carlos.
Marlon Dillinger: The duty manager at the Handy Pavilion. A soft-hearted tyrant. Ally of Ms Shan.
McKinley: A cartoon cat.
Mildred Po: Owner of the Stars in their Eyes telescope shop and amateur rocket scientist.
Mr Smith: The General Manager of the DIY Barn. A somewhat inept Fascist who is nevertheless a threat. Fortunately he is entirely fictional; in the real world inept businessmen/Fascists never threaten anybody.
Ms Shan: Jasu Shan, the General Manager of the Handy Pavilion. Ms Shan wants to view the Pavilion in a bloodless, corporate sort of way but discovers a hidden sense of loyalty to her employees. In love with Claudia Lebeaux. Occasionally also spelled 'Ms Shen' for reasons that I can only assume stem from subconscious racism on my part. Seriously, I can't remember a four letter name?
Nalda Teheintausand: A killer cyborg from the future who works in the arts and crafts department. Also an excellent arts teacher. Very good with children. Friend of Fanaka.
Norman: A young man who dreams of being a big deal in power tool retail. Friend of Fiona, after their involvement in Axel's first plot against the DIY Barn. Comes from a strange family background.

Richard Pennington: A customer. An alchemist, almost certainly with sinister intent.

Sadie MacGregor: Head of the lighting department. Sadie is an extremely moral person, possibly supernatural in nature. She is often present when someone makes an uncharacteristically high-minded decision. Sister to Angela MacGregor, mentor to Donna.
Seamus: A garden gnome who comes to life under the full moon. Speaks in a stereotypical Irish dialect, but the good people of Ireland would like to disavow all knowledge of him. Friend of Zorbar and Bruce.
Stavros Theopoulos: Owner of the Super Center's kebab shop.
Wellsey: Former petty criminal, now head of the plumbing/bathrooms department. Well meaning, but basically in over his head.
Woman in Laplander Hat: Too mysterious to possibly.
