Diego is very friendly. She gets most of her advice from Stoick the Vast. She is quite energetic as Reg And Zed and often gets her work wrong. She is not that calm inside but worries when something goes wrong. She often makes some mistakes. She takes her work like fun.
Diego resembles a JCB 930 Rough Terrain forklift
Diego is Red with her cab, forks, exhaust pipes and tyres being black; she has an orange-yellow warning light on her cab. One of her exhausts seem to have a silver band around it.
