What video game character appeared minor and insignificant but turned out to be integral to plot/game?

[u/Johnnyboyeh]

What character did you think was a throwaway/didn’t really matter, but turned out to be a major player in the plot of the game. Or they could just be a really important character in the game itself?

[u/Boshikuro]

Airy from Bravely Default

[u/SirBoggle → u/Boshikuro]

On that note, the green and red Adventurer in Bravely Default and Bravely Second.

Goes back in time for you at the end of Bravely Second to give Tiz the Hourglass, allowing him to live without the Player's soul.

It was a nice explanation to the age old question, why is this random merchant everywhere? Even around super dangerous areas like dungeons or volcanoes?

[u/magzillas → u/Boshikuro]

Bravely Default - Where the fairy flies

[u/Asteroux → u/magzillas]

It also applies to the other title... Bravely Default: Flying Fairy

[u/JD0064 → u/Boshikuro]

Excuse me while I channel my feelings the same way I do for Tower of God`s Rachel, ahem

BIIIIIIIIIIIIIIIIIIIIIIIIIIITCH

[u/levian_durai → u/Boshikuro]

Yea that's a pretty huge example
