I actually was making a character who essentially can inflate essentially into a big brick character, having two of them wouldn't be bad but I'm just letting you know now.

Also don't be afraid to share your ideas.  Its good to get an idea what people are picturing, especially since it'll be three Earthlings and three aliens.

To give an idea on the suits I was going.  The suit themselves will be a particular color on the main, then silver/white lining and black outlines.  The color in the middle symbolizes which galaxy that particular trooper is from.  With dark blue being the color for Milky Way based troopers.  They all have headpieces which are not only team and HQ communicators but universal translators as well, so if you want to make an Earthling who isn't from an English speaking country it won't be any kind of issue.
