Other characters
Pete Walker (Patrick Niknejad) (1999–2005) One of Josh's long-suffering friends. Pete has a pessimistic outlook on life and easily spots Josh's scams, but usually ends up getting drawn in anyway. His voice broke in Season 2. Pete is often seen feeling sorry for himself. He is also the first to realize all the signs that Brian and Sophie were aliens after Wendy reveals it in "Thanks For All The Earthworm Custard".
Frankie Perkins (Jordan Maxwell) (1999–2005) Along with Pete he's often the target of Josh's scams. He has a long-held crush on Mel (when Mel asked Scott out to the disco, Frankie claims he would have attacked Scott if the table wasn't in the way, (‘First Christmas') and, in Series 7, he has a crush on Harry. Pete and Frankie have tried to desert Josh on several occasions, but have always come back.
Wendy Richardson (Isabella Melling) (1999–2005), Lucy's only friend. In her scientifically minded and studious nature she is very similar to Lucy, but as has been seen throughout the episodes, is perhaps not as smart and is even less in touch with popular culture than Lucy. Pompous, and somewhat arrogant, she will always lose exams/tests to Lucy by 1%. Despite originally having strong feelings for Josh, she gets together with Frankie at the end of series seven due to Brian messing with both of their brains. (‘Thanks For All The Earthworm Custard’).
Terence ‘Trent’ Clements (Keith Warwick) (2000–2005), Mel's long-time friend. He endures Mel's mood swings with resignation and good humour; it is hinted that he is romantically interested in her. They finally get together in series 6. In series 7, it is revealed that his Scottish accent is fake (although Warwick's Scottish accent is real). He is also known as a lothario of the series, much to Josh's resentment; a fan of music and cultural activities. Trent befriends Harry in her first appearance in the show, after finding her using Mel's old locker. He and Harry have a similar friendship to him and Mel's. Trent also shows that he looks out for her by trying his best to convince her not to enter a boxing competition.
Mr Graham Whiteside (Dan O'Brien) (2000–2005), a very grumpy teacher with a particular dislike for Josh Barker. Sophie has a bit of an obsession with him, whilst he has an obsession with Kate Winslet. He can be quite judgmental and is the most feared of all the teachers. Graham often includes himself in after school activities such as first aid, chess club and advanced mathematics classes.
Mrs Alison Hardman (Beatrice Kelley) (1999–2005), another of Josh's and Lucy's teachers who] has a dislike for Josh, and a liking for Lucy. In ‘The Box’, she went to the house to tell Josh that he might have dyslexia. He did not believe her and, thinking that she was Brian in disguise, threw several scoops of ice cream over her head resulting in her leaving the house and vowing to tell his Doctor and The School Counselor to give him extra work about being dyslexic. In ‘Thanks For All The Earthworm Custard’, at the leaving party for Canada she said sorry about giving him extra work. She cannot take criticism shown in the episode ‘Brian's Eleven (Minus 8)’. It's revealed in the episode ‘Dirty Dancing’ that Mrs Hardman had an unquestionable talent for ballroom dancing; she also enjoys her usual job as a Brownie leader.
Poppy Manning (Kirsha Southward) (2002–2005), a girl who frequently appears as a rival to Josh, due to her similarly scheming, sneaky personality. She is also a rival to Lucy because of their moral differences and competitive attitude. She appears mostly in series 4 & 5. She also has the catchphrase of ‘It's too easy’ which she uses against Josh on many occasions while scamming him.
Tania Thomas (Zoe Thorne) (1999); Emily Fleeshman (2001–2002) Sasha Tilley (2004–2005), the object of Josh's affections. In the ‘Valentine's Day’ episode she is shown to harbour a secret affection for Josh, though he mistakenly believes she has sent him hate mail and is determined to get back at her. Brian's well-meaning attempts to ask her out while morphed as Josh apparently ruin any potential relationship. She gets together with Pete Walker in series 7.
Mikey (Chris Cornwell) (1999, 2005) appears in the first series, as good friends with Josh Barker, Pete Walker and Frankie Perkins. He is perfectly happy being Josh's third-in-command and is most commonly used as a look-out. He makes a cameo at the end of series 7.
Dave Locket (Julian Triandafyllou) (1999), a cool, good-looking and popular - but very unintelligent - boy in school. Although originally Josh's idol, the two later sink into rivalry, most notably in the episode, ‘The Home Team’. He is particularly fond of his hair.
Andy ‘the Freak’ (Danny Robinson) (2000–2005) appears throughout the Barker era as a repulsively geeky boy who is in love with Mel and is deluded in thinking that she returns his ardour. In an episode in Series 6 (‘Le Freak C'est Chic’), he gets a makeover. His cousin's name is Jamie, a football player who Mel was briefly infatuated with in the episode, ‘Magic Johnson’. He almost discovered that the Johnsons were aliens after seeing Sophie as a mermaid while fishing. However, the family successfully convince him otherwise as he went in pursuit of her after falling in love.
Scott Taylor (Marco Williamson) (2000) is a popular boy who Mel had a date with in the episode ‘First Christmas’. He is the head of the school football team and will not, to Josh's dismay, let him have a place on the team.
