Its just a chibi Santa Natsu. I think yours has already been guessed...but it was wrong. I don't know either...
That looks like Super Sonico from Nitroplus.
Also, Natsu Dragneel from Fairy Tale?
My mind is going crazy right now...
I know, it's a video game and not anime related, but the video show some anime content in it. This video shows all the emblem/decals that was created on a video game called Armored Core V. These images are amazing and just wondering how much effort they put into it.
And as for bonus, can you tell what emblem/decals are shown (character, anime, video games, etc)? Also, what is your favorite emblem/decals in this video?
EDIT: Damn. This topic suppose to go on "Off-topic" forums, but let see what the moderator thinks.
