Ben cannot do without excellent visual memory. By the nature of his activity, he has to meet with a variety of creatures from distant planets. Some of them are friendly and help earthlings and Ben as well, but most of those who want to either destroy our planet, or conquer and enslave, or pump out all the resources and turn it into a lifeless desert. The creatures inhabiting the Universe are completely different, each race has its own characteristics and our hero in Ben 10 Memory Universe needs to remember everyone in order to know their strengths and weaknesses. Therefore, the hero regularly trains his memory in pictures depicting aliens. You, too, can join the Ben 10 Memory Universe in the training and show your skills and abilities.
