@geraldthesloth: Because of Orion's location of creation which is in a realm called the Source, it seems as if using the energy from the Source Wall and using their own kind of technology has evolved Orion into something of a perfect superhuman. That way, they have the same physical image of humans, but are smarter, stronger and faster. His strength is unmeasured, but he has been able to defeat Darkseid once and has been able to hold up against the heavyweights such as Superman and Wonder Woman. He is impossible to stop on Earth as any substance has been known to have been destroyed, but barriers from the Source Wall have been known to stop him at some point. Because of his rage, Orion does not tire easily though he is not entirely unstoppable, showing fatigue when fighting against Darkseid. In battle, his healing factor is shown to help, healing him if severe injuries ever occur. With more serious injuries, he can use the Mother Box to heal him and supply him with more energy to continue fighting.
Orion also is able to harness an inter dimensional energy called the "Astro Force". Also known as the "wrath of the Source" it is an energy powerful enough to destroy planets, equaled only by the Omega Force under Darkseid's control. While Orion himself is a conduit for the Astro Force, he can use either the Astro Harness or his wristbands as a valve through which he can project this energy. He uses the Astro Force primarily as a weapon, but once he was shown to be able to use the Astro Force to create an energy shield powerful enough to deflect Darkseid's "Omega Effect". It should be noted that Darkseid wanted this to happen, so the end result might not be that accurate.
Even though a god, Orion still has weaknesses. One weakness is a substance called Radion. The average god cannot withstand its damage, though Orion who is more advanced, with armor and the Mother Box can take a couple hits and survive, though it probably puts Orion in a very weak state. Another weakness is the way he thinks and how he goes about doing things. He is a warrior of rage and will stop at nothing to defeat his enemy, even if it means destroying many innocent lives. For him to be restrained, he has to be constantly reminded and on one occasion, been punched to calm him down. Also, because of his warrior trait, he does not know the difference between weakness and defenselessness even though he is highly intelligent because of his race.
