A 200 year old Wookie native to Kashyyk, Chewbacca is one of the few characters in the Star Wars universe to be considered war heroes in both The Clone Wars and the Rebellion against The Empire. He was one of the main go to guys in the Battle Of Kashyyyk against separatist forces. After the war, Kashyyyk was enslaved by the Empire. Chewbacca managed to escape captivity and spent the next few years of his live as a smuggler alongside Han Solo.
As a Wookie, Chewie is much larger and stronger than even a peak condition human. He stands at approximately seven and a half feet tall (2.28 meters), and has enough natural strength to dismember most opponents. Chewie's main weapon is the wookie "bowcaster" which fumctions similarly to a crossbow, but fires energy blasts. He also has natural claws which can be used as weapons, but Wookie culture considers use against unarmed opponents to be dishonorable.
Skeletor possesses an array of mystic powers and is an extremely powerful sorcerer with control over a vast range of dark magical powers. He also possesses considerable scientific skill, and is shown to have skill in creating various machines and devices in both the Filmation and New Adventures animated series.
He is usually armed with a magical weapon called the Havoc Staff; a long pole crowned with a ram's skull (and in some depictions, a crystal ball embedded within). He can discharge bolts of mystic force from the head of the staff, or use it as a focus for more powerful forms of magic. Skeletor has also displayed the ability to discharge energy from his own body, as is seen in the 1987 film where he casts lightning from his hands, and in the original animated series where he projects energy from his fingertips. In the 2002 series, his innate powers seem much more limited; though his abilities, when in conjunction with his Havoc Staff seem nearly unmitigated in scope and highly potent in raw power.
In the early mini-comics, Skeletor sometimes possesses one half of the power sword. From this weapon he could also project magical energies. He also displays many other skills, such as the ability to teleport himself and others over vast distances, send telepathic commands to his minions, open gateways between dimensions or perform remote viewing. He has also shown himself to be a gifted swordsman. As a master of the occult arts, he is also privy to much secret knowledge about the universe.
