Abilities
Snake-Eyes was a master of ninjitsu and was probably the most deadly fighter in the whole of GI Joe. He was a master swordsman and hand to hand combatant as well as being a master of wielding tonfas. He was also able to throw shurikens with lethal accuracy and during his youth his also displayed skill with a nunchaku though he was unable to best Storm Shadow whilst using the weapon. Snake was the only known person in GI Joe who was able to combat Storm Shadow as an equal. He was capable to performing amazing athletic feats as well as moving with great agility. At one point he even managed to fight Shadow whilst gripping onto the side of their vehicle.
Abilities
Queens are much larger than Drones and Warriors. They stand approximately fifteen to twenty feet tall at the hip. They have twin sets of arms and are built more similarly to a large theropod dinosaur than a humanoid. They also have a much larger braincase than the average adult Xenomorph, protected by a large crest above their heads. They also have a slightly stronger tail, which can be used as a weapon, along with their limbs and inner jaw, as shown in the climactic battle with Ripley in Aliens. Due to their immense size, they are extremely strong.
Another well-known feature is the immense ovipositor in the Queen's lower torso, which is responsible for creating eggs (similar to a queen termite). She is able to detach from the ovipositor in an emergency, and will regenerate a new one when the danger is over. Queens also have a higher ability to relate cause and effect, and to make observations and deductions, allowing them a rudimentary understanding of technology in the same way as some primates - ex. The Queen's use of an elevator on LV-426.
The Queen is also considered to be the strongest caste of Xenomorph, able to evenly fight Ripley in a Power Loader in Aliens. Queens seem more resilient to damage than the rest of the hive (even when adjusted for size), as demonstrated in Alien vs. Predator. She receives several deep throat wounds and is speared through the head, and yet remains alive.
