Lana
Chance: 0%
While Hyrule Warriors was a successful game on the WiiU to the point it has a 3DS port, Lana isn't a true Zelda character. In fact, she's basically your modern day Geno; she was developed by a third party that appears in a game filled with Zelda characters. While she could make for an interesting mage-like moveset (which is a fighting style Smash could use more of), her third party + spin-off status and lack of ballot support don't help her much, especially with Zelda characters like Tetra, Impa, and Beast Ganon being the more probable candidates due to having far more ballot support and actually being first party characters.
Want: 1%
As interesting of a fighter she could be, I think there are
far more deserving characters for the 5th Zelda slot.
Oliver
Chance and Want:
While returning from the local castle, Oliver was just walking down an open path leading to the nearby woods when he noticed a giant, floating object emerge from the nearby lake that resembled a dragon with extra armor.
"What a
beautiful dragon!" exclaimed Oliver.
The floating object flew toward the sky. It then became enveloped in what looked like whirls of wind as a large hole suddenly opened up in front of it. The floating object flew through it, and the hole closed. Oliver, shocked, thought to himself, "That beam had a certain air of beauty to it, and so did that hole. Perhaps the gods blessed it with such profound
beauty that it can do these
beautiful things".
But suddenly, an explosion of energy appeared behind Oliver, blasting him so high that he eventually landed within the lake.
"Oh... ahh... I... cannot... fall here... It cannot... be... such a... loss... to beauty," muttered Oliver just seconds before he landed into the lake.
^Oliver's death quote as a boss in Path of Radiance
We then see where the object went when it floated through the hole. A shadowed figure can be seen talking in the next scene.
"What a pity, Oliver. Because of your boss characters status and minuscule ballot support, you have no possibility of joining Smash Bros.. but I'll help you. *Laughs*
^This line is based around a quote Zero says in 11th Pokemon movie, where he says, "What a pity, Giratina. Because of Dialga, you lost your ability to travel back to the real world... but I'll help you. *Laughs*
Then, a large pink blade emerges from the bottom of the object and attacks a nearby crystal. This attack is revealed to be the cause of that explosion that sent Oliver flying. Ominous music starts playing as the camera zooms into the control pit of the floating object as the perpetuator of the attack is revealed to be...
Regarding Chance:
While Oliver already has some form of representation in Smash thanks to his theme song, Power-Hungry Fool, appearing as one of the music pieces for the Castle Siege stage, he is nothing more than a minor boss character in both of the games he appeared in. When it comes to adding boss characters, the ones that are added are usually the ones that have the most importance to the story, like the main villain or the main villain's sidekick. Oliver is neither of those, so adding Oliver would be like adding Rawk Hawk from Paper Mario:TTYD or the Paint Roller from the Kirby series.
While he is playable in Radiant Dawn, the playable Fire Emblem characters that are picked for Smash are the ones that are the main stars from the games they come from (like Ike, Micaiah, Marth, Robin, etc.), not the ones that are support playable characters like Oliver. In that regard, adding Oliver would be like adding Libra or Cynthia from Fire Emblem Awakening.
Finally, he also has minuscule ballot support and fans are already starting to think 5 Fire Emblem reps are enough now that we have Roy. I think it's safe to conclude things aren't looking good for the beauty-fascinated man.
Regarding Want:
I'd take Micaiah over this power-hungry fool for a Fire Emblem rep from Ike's games, and in terms of Fire Emblem villains in the Smash roster, I'd take Validar over him; at least Validar was far more important to his game (from the Fire Emblem game that saved the franchise, whereas Path of Radiance and Radiant Dawn were the low points of Fire Emblem in terms of sales) compared to Oliver, but even then, I'm more interested in seeing the main heroes of the Fire Emblem franchise join the Smash roster.
