Community's non-official tier list. Day 35: Nanomech

This tier list is driving me crazy. You guys managed to put Brainstorm above Gray Matter (They at least should be in the same tier), Four Arms above Humungousaur (He's stronger) and Jetray in the same tier as Wildmutt. But that's not a bad thing, I decided to do this because I wanted to see what happens when you put more than one person doing a tier list. And so far, the results are... somehow goofy. But I like that most of the respected aliens like Big Chill, Swampfire, Rath and Cannonbolt are in the S tier not only for their powerscale, but because they are loved by you. Oh, and, Alien X in F tier... uhhhm... just DON'T DO THAT AGAIN

Most upvoted comment decides his spot on the list.

I'm not going to include ultimates, fusions or aliens outside the main series, just the 67 aliens that appeared and were used by Ben on-screen. Ken's Sandbox, Shellhead and Snakepit aren't included

Reboot aliens Overflow, Gax, Shock Rock, Slapback and Surge are going to be included at the end

I didn't find anyone doing this before, so I'm attempting to do this now. If someone already beated me to it, please let me know. I'll just delete this tier list.
