My best Arkadion is Glazio then Georex and then Vulcaraptor those are my best each lvl 99 exept Vulcuraptor hes 96, whats the arkadion I need to beat him
Just have as many strong arkadions in your team. But be careful if you have strong Shadow monsters. They'll die very fast and they don't deal a lot of damage.
Always have Don Penguini with you.
And yes, after you defeat him you can use him in battles too.
What do you think?
