Född 1961 i Lund, uppvuxen i Stockholm och bor i Nacka utanför Stockholm. Måns Gahrton är mycket produktiv som författare. Han tecknade sin första serie som femåring och skrev sin första bok när han var sex. Han fortsatte skriva berättelser under hela sin uppväxt, men det var första när han träffade illustratören Johan Unenge (vid den tiden reklamtecknare), som han vågade gå till ett förlag. "Vi träffades på en fest för tjugo år sedan. Jag ville göra serier, men kunde inte rita, Johan kunde rita, men inte skriva. ’Jag hittar på och du ritar’, föreslog jag fram på småtimmarna, och dan därpå träffades vi och satte igång med vår första figur, som vi döpte till Agent Annorlunda."

ohan Unenge, född 1963 i Stockholm och nu boende i Enskede, är mycket produktiv både som tecknare och författare. "När jag ska hitta på historien i mina serier blir det tvärstopp", sa Johan Unenge när han på 80-talet träffade Måns Gahrton och började teckna till hans manus. Men i Mållösa United delade de på författarskapet (fortfarande med Johan som tecknare) och därefter har de tillsammans skrivit ett antal serier ihop, bland andra Livet enligt Rosa och Hotell Gyllene knorren. År 2002 debuterade Johan dessutom som författare på egen hand och det har blivit ett tjugotal böcker hittills. Johan Unenge försågs tidigt med drivor av ritblock av sina tecknande föräldrar och gjorde sin första riktiga längre serie som tolvåring. Han har tecknat hela sitt liv, och arbetade under en period som reklamtecknare. Redan som 25-åring debuterade han med tecknade serien "Agent Annorlunda" tillsammans med Måns Gahrton. Därefter har de arbetat tillsammans med en mängd projekt. Ibland med Johan som illustratör men oftast som författarpar.
