Who has greater fighting ability? Logically it should be Orion due to the intensive training he has had and the chance to practice said abilities for thousands of years. He does however lose his temper and resort to straightforward brawling. However WW has had the chance to show better feats, so WW. Whos physically stronger ? WW. Orion has a strength level that was around the same level as Kalibak's and on par with Darkseids, both of which have usually shown to be inferior to Superman's. WW runs a close second to Superman in strength so I favour her for being the stronger. Whos faster? In reaction speed and acceleration, WW, as she has the true super speed power. Orion has significantly enhanced reaction speed but not to the level that WW can employ via her super speed. In top flight speed, I think that Orion should win as the Astro-harness proviides him with vast flight capabilities. Whos tougher? I don't think that there is a lot in it between the 2. Both have taken on Superman and other major powerhouses and both have taken damage from these battles. If I had to favour one, I might be tempted to go with Orion, but only by the slimest of margins. Whos smarter? WW from what we have seen. Orion has the capacity for very clever tactical and strategic thinking and has shown a keen intellect in these areas but his anger get's in the way.
