Suggested by Anonymous Lumine is a pretty epic villain and has one of the better designs in the X series. He has an extremely wide variety of moves since he can tap into other Reploid abilities. Eternatus is a fierce Pokemon and one of the strongest dragon types as well, but I don’t see him being able to take down Lumine. Lumine will be able to match him blast for blast while also dealing extra damage with other attacks. He can fire off more lasers at once than Eternatus can and that will be the difference in this battle. Eternatus just won’t be able to keep up. Lumine wins.
