Everyone's character should be based on a Warframe character design, but our origins and such will be a little different. I actually thought of tying the Dark Sector game that came before Warframe into the story somewhat, at least to give our Vanguards a little more backstory. 

For example, centuries earlier when the Vanguard were created... they were regular humans who volunteered for the program. They were injected with nano-machines that gave them more of a bio-mechanical nature and outer shell on their first mission against invading aliens. 

Basically the nano-machines slowly remake your body, almost similar to the symbiotes in Spiderman. 

First you're normal...

Then after the nano-machines begin readying you for battle...

And then after you've completely been augmented by the nano-machines...

Of course at this point we've all already been augmented completely. We're still human under the armor, but we've only been released maybe a total of one month during the three invasions in the last few centuries. If we move forward with the RP and we get through the Unknown, we may keep the Vanguard out of cryo-stasis this time around.
