I am a bit puzzled by it I think the "orus" is like "saurus" which is used at the end of many dinosuar names like Tyrannosaurus. The first part I think is a combo of Hack and Axe because they his pre-evolution he has axe like teeth or tusks. Also it could refer to Hax as in his attack is so high and with D-dance it is practically hax. so is he a hack-axe-osaurus or a Hax-osaurus?
