Scratch

I am trying to find movements for a project I am making. The movements could be something like this: http://i238.photobucket.com/albums/ff94/Zaraxion1021/Bleach%20GIF/Ichigo.gif

I am having difficulty knowing what I should type in to search for images that can preform actions. Note that what I am trying to find is a picture or pictures that show frames of movement like that, so that when I use them in the project, I can put in or cut out the pictures separately to make actual movement in the game. If someone could help me find out what I should search for, that would be much appreciated.
