Well I’m afraid Marth can’t beat the Hero of Legend. Roy is just too powerful for Marth and won’t lose here. Marth may have a decent sword but Roy has the legendary fire sword used only against true opponents, so in other words he probably wouldn’t even use it in this match. Roy wins.

Ike could beat them both
I agree that he could beat Marth, but Roy? Roy was pretty impressive in the Fire Emblem manga. He took on this super powerful being named….forgot his name. And he showed pretty good speed and power. Of course Ike probably has more power as showed in SSBB. (He didn’t win, but it was a good fight)
