Representation in smash games:
Three Times Tier
FE1 (Marth melee/Marth brawl/Marth ssb4, also Tiki trophy)
Once Tier
FE6 (Roy)
FE9 (Ike melee, various trophies)
FE10 (Ike brawl, Sothe trophy?)
FE7 (Lyn assist)
FE13 (Arena Ferox stage)
Never Tier
FE2
FE3
FE4
FE5
FE8
FE9
FE11
FE12
this might be a little controversial but I maintain that because the Marth trophies point to his original appearance in FE1 as his home title FE3/11/12 have never been represented
