NEON GENESIS: EVANGELION
If you clicked on the NERV picture, you are probably wondering what it is. NERV is an organization that was setup to help the human race combat some mysterious beings called angels on the anime Neon Genesis Evangelion. I put this link here to tell you about this excellent series and if you ever get the oppourtunity to, you should watch it, the ending is especially confusing and good. Plus, if you like giant creature combat, it has lots of that too and some funny parts.
