I'm bored, so I thought I'd share with あなた a few websites online that あなた can デザイン your characters! There are tons of websites out there, these are just a few.

This website is によって far the best superhero generator I've found. Basically あなた use it to make your character in costume. They have endless options of costume parts for both male and female characters, and they even allow あなた to 移動する parts around, resize them, and color them. あなた can save the character to the game, and then load it later, but if あなた want to save an image to the computer, あなた have to take a screenshot.
Heromachine 3 Superhero Generator

There are lots and lots of アニメ maker games on Deviantart, but this one is によって far the best, and one of the cutest, in my opinion. It has an almost overwhelming amount of hair choices, and other face options. Since the アバター is from the shoulders up, あなた only see the 上, ページのトップへ part of the clothes, but they still offer a wide range of clothes options. あなた can do a boy または a girl (the only thing that has seperate items for different genders is the clothes) and the only way to save is によって taking a screenshot.

あなた probably know that there are tons of dress-up game websites out there, but I find this one to be によって far the best. They have lots and lots of games to play, some アニメ style, others not so much, that vary in the amount of options and items あなた can use. Some of my お気に入り games are the Fashion Creator Dress Up (where あなた can デザイン an outfit), the Shoujo マンガ アバター creators (limited options, but really cute) and the link (there are 11 pages in all, most of them are on the romantic side). This website does have a save option, which automatically saves an image to your computer.
Rinmaru Games (Video Game アバター Creator V2)

link
This makes cute, tiny, chibi-style characters that あなた can save によって taking a screenshot または によって saving it to the website. There are lots of clothing options, so many in fact that it's almost impossible to find what あなた need によって browsing, so I recommend that あなた use the 検索 bar または narrow the 一覧 によって color または item type.

This is just one of the many Deviantart ちび makers out there. It's a simple little drag-and-drop game, and it's really cute. The only way to save is to take a screenshot. (Plus there's a special hidden button...find it if あなた dare!)

From the creator of the アニメ face maker, this ちび Maker is pretty much a full body version. It has a lot of great options (especially for hair) and an amazing range of clothes and accessories. Plus, it's super cute! There is a save button, but I personally prefer taking screenshots.
ちび Maker 1.1

link
This is a super cute little ちび creator. There is a huge range of options for hair, face, outfits (mostly dresses and anime-type clothes but there are literally thousands of things to choose from and lots of 'boy clothes' and stuff also), and accessories/backgrounds. The 検索 feature isn't all that great, however, but it's endless fun to look through the different categories and pick cute stuff (you can sort によって theme-category, color, type [shirt, hairstyle, etc.], または search). To save an image to your computer you'll have to screenshot but the site gives あなた the option to save a link which あなた can bookmark on your computer and access anytime, and a window to view and screenshot a big または small image of your chibi.

So that's all I've got. If あなた guys know of any other good websites, let me know and I'll add them to this list! Bai now!
