okay so here is the full armored version now. she still looks like something from gears of war and for a big Charizard like her, it does fit.

I did have some idea of Karen's background too on how she would be part of the 40k world. one idea I had is that during an Ork Waaagh Karen mom who was pregnant at the time with her. took combat knight from an Astartes cut her self open and gave birth to Karen a day early and Handed her off to she can live on while she stayed and behind to take fight Orks that invaded the facility. this would give the Astartes time to get away with her child to a safe area.
it gives an epic Idea of how Karen came to the 40K world. she was born in battle. it would also give her a reason why she battles so hard and wins every fight she in. It for the honor of her mother's sacrifice.

that just one of the ideas

but yeah to keep this short this was fun and I think I might do more of this version of Karen and work on her bio more.
also taken inspiration from Gears of war too.
