I like the high speed andmobility design and I especially like how it's rifle is used. By modifying it and still maintaining it's main structure, it's possible that the weapon could be altered during combat.
I'll give a brief description. It's a mobile suit with a head like the Vayeate from Gundam Wing, has thick armor plating on its hand, forearms and shoulders, normal sized legs, feet and torso and only uses an assault sword. I got the idea from a fan made mech that I found off the internet somewhere.
