With LLyn and LHector now we can say IS will introduce various legendary characters from the same game (FE7 in this case).
SOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOoooo there is a little chance to see Eirika in future legendary banners!
Also Alm a/o Celica, Sigurd a/o Seliph, Leif, Micaiah or even Hinoka and Takumi.
I mostly wonder what will the devs do when they release each stat bonus (atk, def, res, spd) legendary hero for each type of blessing. Are they going to come up with a second generation of legendary heroes or up the ante with divine godlike heroes who will use different mechanics than the blessings?
There's a good news and then there's bad news. First of all, yes, Marth, Seliph, Alm/Celica, Eliwood, and Eirika are headed, they always have. It just hasn't been their color. Now, to make matters worse however, I don't want FE Fates LEgendary Heroes other than Corrin and Ill explain.
They posted a little chart with a set number of spaces for what we could get in the LHeroes department (Likely to be expanded, but Im assuming it wont for the moment) That only makes it seem worse. There is also the fact that we already have a legendary hero for FE8-9 is Ike, as historically, people remember the Radiant Hero. Then again, we got Ryoma (still annoyed by this one) so I guess it's not surprising.
Honesltly, I think IS wont stop making new legendary heroes even when all types and colors are completed. I mean, its an easy and attractive way to obtein money. And Legendary banners are actually like a normal part of the game. I think every Lord (and some tacticians) will have their own legendary version:
Marth, Alm, Celica, Sigurd, Seliph, Leaf, Roy, Eirika, Ephraim, Lyn, Eliwood, Hector, Ike, Micaiah, RobinM, RobinF, Chrom, Lucina, CorrinM, CorrinF, and maybe Xander and Ryoma (I dont think little princes get a legendary version).
If they want to expand the legendary slots, they can introduce Caeda/SHiida (Marth`s cannon wife), Lilina (very important character in FE6) or even Julia, Deirdre, Leo, Elise, Camilla, Sakura, Hinoka, Takumi and Azura.
