There are multiple different types of avatars that you can create online for free. You can make a superhero version of yourself with the Marvel Create Your Own Superhero website. You can also create a Mad Men avatar on the AMC website under Mad Men exclusives.
Marvel Create Your Own Superhero allows you to create a superhero or superheroine avatar. First, select which body type you'd prefer, then utilize the menu on the left to navigate through different attributes, outfits, and accessories. Use the color picker to choose which colors you prefer for each attribute. In order to color in each attribute on your avatar, you must hover with the marker tool until that attribute is highlighted and then right click to fill it in with your chosen color. You can also choose a name for your avatar and then share it with friends or save it.
With the Mad Men avatar creator, Mad Men Yourself, first choose "suit" or "skirt," then select your skin color, body type, hair style and color, facial features, outfit and accessories. The avatar builder allows you to navigate backward and forward through options in case you change your mind about a characteristic you've already chosen. After you've finished your avatar, you can choose a backdrop and then share your creation on Facebook or save it to your computer.
