I made a Big Barda cosplay for Rose City Comic Con this past weekend, and it came out great! I got a lot of compliments, and I only sweat moderately. (Note to self, it doesn't matter how much you like the blue yarn for the legs and torso, worsted weight is not con-friendly).
With the exception of the hexagons, I didn't use any patterns.
Legs, torso, and gauntlets are crocodile stitch. The cape is triple crochet. The rest of it is half-double. The megarod (my totally not-phallic weapon) is single crochet with bubble stitch on the top and the buttons were stitched on separately.
Let me know if you have any questions! I actually got some in-progess shots for this one!
