Eva is the one of the characters for the book and the series by the same name.
She's a ecological giraffe who wants to protect nature. However, it fails to raise his comrades, quite the contrary. Its a bit aggressive nature led her to use bad methods to prevent others from polluting. Transformed into Superécolo, it has the power to grow plants in one second from seed. It ignores the feelings of Malo to him. In an episode of the Gang of Minijusticiers, we learn that she has a small white dog named Praline.
Eva has always loved animals, and since childhood, she fought tooth and nail. Well, it's true that sometimes it makes it a little too much, and well aware. So, with time, she learns to respect the choices of each. But woe to him who touches a horse, cat or even a gnat!
