Ben 10: Hidden Aliens
Ben Tennyson, the master of omnitrix transform into different aliens to battle the scum of the universe. With each battle, the number of aliens to which he can transform remains the same, but the aliens are becoming more powerful. This game would see if you have a 20/20 vision. It is true that all the aliens to which he can transform into are all in the picture, but those aren't the aliens that you need to look for. The aliens that you need to find are little and can't be easily seen if you are not going to look for them.
