Useless characters

[Depression Moon]

I don't see how Freya, Vivi, or Eiko drop out of the plot.

Freya is affected by the plot when she meets Zidane. He is a former friend of hers and is integrated into the plot when Queen Brahne makes an attack on her home. The attack expands to the other Burme- rat home in Cleyra. Fratley her long lost love shows up saves Zidane's skin talks to Freya. Freya finds out he has lost his memory. The general Beatrix shows up steals the kingdom's ancient jewel, and Freya wants to get her revenge. They lose and Brahne is about to destroy Cleyra in minutes. There is barely any time to escape and there's no choice for her but to escape in one of those pods.

With both Burmecian homes destroyed Freya is bent on avenging her people. She is a Dragon Knight after all so she had some rank and dedication to her country. I can't remember clearly, but after the event in Alexandria I believe she and the others stayed to see Garnet's coronation. I sort of forgot how they wound up in Lindblum. Ultimately Freya continues on she wants to keep close to her friends and wants to protect her people and/or avenge her home by eliminating the person who started the whole mess, Kuja.

As for Vivi, well there's little need for any explanation for that. Black Mages is all you need and I believe Vivi had to be lonely as well and a bit afraid. He stayed in a secluded area with his grandpa and was alone for a few months after he died. So lonely people feel comfortable with company.

Eiko had to be the loneliest of them all though. She was the last survivor of her tribe and was living only with moogles for a time being. She also had to steal to eat. When she met Garnet, she was excited to see another summoner. The main point when she becomes a part of the party is when she breaks her promise to her grandfather and leaves the village so that she can see the world.

Amarant joined because he was interested in finding out what Zidane's deal was as he didn't believe anyone could be that noble and what made him so strong. He also had a bit of beef against since he set him up a few years ago. He was curious astounded when he saw the power of the Eidolons. When they went back to Alexandria...hmm, I guess he just continues because he's still not sure about Zidane?

As for Quina yes she was primarily meant to be a humorous character, but Quina also shows that the bizarre are actually not so bizarre and she shows that she cares more than just about food. As for battle purposes, maybe you don't know how to use her. She is a Blue Mage that acquires her abilities by eating weakened monsters. These abilties come with a wide amount of varities. I mostly used White Wind (healing), Magic Hammer (MP depleting), Earthshake (ground damaging), Twister (air damaging), Frog Drop (number, lvl based damage), Angel's Snack (erasing), and Matra Magic (Quick eating and boost for Pumpkin Head and Limit Glove) with her, but I also used Mighty Guard on occasion along with Limit Glove, Pumpkin Head, Frost, and Mustard Bomb for 1 hit kills. Quina's weapon deals random damage but there is a good chance for it to do a lot of damage and some of her weapons have excellent effects like Needle Fork which petrifies, Silver Fork which slows, and I can't remember if any others had effects attached. You can also use 1000 Needles to have her do consistent damage. Quina is also the only one who has the Gillionaire ability.

See? She has a lot of options.
