Xenogears - Unknown Enemy Revealed! - Id (Boss) 

Extremely badass fight. That is all. Also, no video for Friday.
Overview
In this fight, you will get your ass handed to you by Id, who is now revealed to be that unknown enemy. Don't think this is one of those scripted to lose fights that you might be able to win. You CAN lose this, and will Game Over if you do.
Video Spoilers
So if you recall from the "Unknown Enemy" video I put up, I mentioned how this enemy is Fei when he goes "out of control" and becomes this scary intimidating powerful enemy. So you're probably wondering why he doesn't look like Fei. Well, both Fei and his Gear transform to look different in this state. Only Citan knows who he is and for some reason does not bother cluing everyone else in (or perhaps he isn't certain).
You'll probably also remember that Id looks exactly like the person in the flashback from the first Xenogears video I put up. That's because Id is that person. You also probably remember I stated that Id will be explained fully eventually. This is not the video it will be explained in.
Stats (note: copied from previous fight, might be a level off for some)
Citan: LV42 - Penguin Coat, Metal Helmet, Step Shoes
Bart: LV41 - Black Snake - Penguin Coat, Leather Hat, Stanima Ring
Elly: LV42 - Lunar Rod - Penguin Coat, Silver Beret, AntiEthStone
Strategy
Okay, the general strategy is to just freaking stay alive. Which is hard to do with Id constantly pummeling you. He's able to do two Deathblows in one move sometimes, meaning if he hits the same target with it, they're KOed. So hope you packed plenty of Zetasols to revive them right away.
If you were smart and brought Billy into this dungeon unlike me, then his full heal will be immensely helpful here. If not, you'll have to rely on Citan to heal, which will suck because he may be your power character right now with his strong Deathblows.
There's really nothing else to mention about this fight. Just keep everyone alive at high HP at all times and keep slamming him with Deathblows when you get the chance and you should become victorious.
