ya know what, tadpole? screw the dimensions. gather information from bubblegum crisis, gundam, and macross to create the ultimate small yet powerful (and morphing?) mech, then cross-reference it with a cool fighter from mortal kombat. that way you've got not only cool mech weapons, but if it came down to it, you can also throw a spear, do a superman lunge, teleport kick, or hell even a freeze bolt in order to achieve the dominance you desire
