In the cartoon though, there are only 5 stones. The film series HAS confirmed 6 total, right? Wonder why they did that.
It also made me want to see Doctor Strange, too.
not really familiar with the original story as I'd like, but in the cartoon they may have cut it down to 5 to simplify it. However GOTG hinted that there were more infinity stones, (1 per a original galaxy.) so there may be 7 or 9? not sure of the exact number.
