And now we're at Day 15. Actually, the day was here several days ago, but I've been busy, what with will be in another post. Sufficed to say, this is our Video Game Music Challenge post!

For those of you just joining us, this is Day 15 of a 30 Day Video Game Music Challenge; if you missed the first fourteen days, they're all grouped together in the same category, at the top of the article. Each day consists of a different category of music, and I respond with a song that I feel fits it well, in terms of being one of my favorites of that category. Hard mode: I can't repeat games. Challenge mode: I can't repeat franchises either. (Repeat characters appearing in other franchises are fine.) In each entry, I've also been providing an honorable mention, a song that fits the bill quite well; in order to avoid removing other franchises from the running, I've been keeping these honorable mentions within the same franchise as the original item. Got it? Good!

Today's topic is "Boss battle music", and while I had a hard time coming up with anything that came from a franchise I hadn't already used, I finally decided on the final battle theme for Illusion of Gaia, titled "Threat of Dark Gaia". This song plays during the climactic final battle of the game (though not the most challenging boss battle, if you know about Gem~), and when I finally reached it, OH, I was thoroughly impressed. It's still a wonderful song, and I feel truly matches the level of the destiny of this battle. If you win, you save mankind--at great personal cost. But if you lose, the world as you know it is destroyed.

For an honorable mention, there's really only one other boss song in this soundtrack, and that's the general boss track, "The Guardian". It's a good song too--really, every song on this soundtrack is amazing, and if you've never played the game I cannot recommend it enough--but its intent is to match the intensity of the battle on Earth, strong and stressful, but with no idea as to the gravity of the situation.
