Sorry but, wich relation there is between Link and Marth? Why they ever argue????

there is none in the legend of zelda games i playd BRALW and there is no conetion there as well so...

There is no relation between them, since they re from different games (Link from LoZ and Marth from 火, 消防 Emblem). Not even in Subspace Emissary of Super Smash Bros Brawl they get directly together. The only thing is that both are in the good side :)

there is no relationship

I have no idea.....(gets attacked 由 RedLink) AHHHH!
