The Gundam They Called Xero
Work on a colony is underway to prepare for their joining the OZ, as an unidentified shuttle suddenly shows up on their radars. As the shuttle doesn't answer, the colony sends out mobile suits to protect them, and fire at it as it is in range. They believe they have hit it, when the object they thought was a shuttle transforms into a Gundam... The soldiers panic, and fire at it. They think they have the Gundam immobilised, when it suddenly turns around and fires at the colony, blowing it up. Inside the Mobile Suit, the pilot is breathing heavily, only one wide eye visible in the darkness...
Tsubarov argues with Lady Une - why keep the Gundam pilots and the scientists, they're far too dangerous. Lady Une comments that they're excellent pilots, and that Tsubarov is only jealous. Lady Une suddenly gets a report that their new resource satellite has been destroyed by a Gundam not previously in their records. When Tsubarov wants to know how they know it's a Gundam, the messenger says that the pilot sent out a warning message that he'll destroy a civilian colony, and attached Sandrock's blueprints to it... Lady Une orders Vayeate and Mercurius to be sent out.
On someone's computer, pictures matching the Gundam pilots with their scientists shows up, but the 4th slot for the pilot working with Professor H is not filled in.
In the moon base prison, the professors note that something is going on, when Trowa arrives and gives them a report of what's up. He tells them that a new Gundam has appeared, and that it's threatening to blow up a private colony. The professors wants to know about the suit, does Trowa have any more details on weapons and configuraion? Trowa tells them that is appears to be based on 04, Sandrock. Professor H is surprised - Quatre? Trowa thinks it's probably him, and comments that the suit has enough power to totally destroy a colony. He says he'll investigate more before he leaves. The professors realise that Quatre has done what even they hesitated to do - built the origial Gundam from the blueprints left behind on L4 by Professor H. Dr J has a bad feeling about this, and professor G comments that Quatre is either stupid, or has gone wild. Either way, one or two colonie is about to be destroyed.
Trowa recruits Heero for the mission of piloting Mercurius, and Duo protests this, he's better than Heero! Trowa states that he's in no condition to fight this enemy, which is a Gundam. Heero wants to know the details, and Trowa tells him what he knows. Heero says he'll use the Mercurius, it will be suitable to fight the Gundam with. Duo gets angry, Trowa's just going to sit there and watch as two Gundam pilots fight each other? Then he tells Heero to not help them. Trowa answers with hitting him in the stomach, stating that he'll get his opportunity later... After they leave, Wufei comments that Trowa plays his part so well there's questions whether he's not switched sides completely. Duo doesnt think so, he says they can trust Trowa. As Wufei wonders why, Duo picks up a little device that Trowa gave him whille hitting him. It's a image displayer from the professors, and it shows the specs for the new upgraded Deathscythe and Shenlong.
On their way to Vayeate and Mercurius' carrier, Trowa tells Heero that Deathscythe and Shenlong have both been upgraded now, and that the unknown Gundam has to be Quatre. Trowa states it's time to join up with Quatre, and attack the OZ. Heero questions this - how can Trowa know he's still on their side, assumtions like this can lead to mistakes. Heero says they'll investigate the Gundam first, then destoy it if it isn't what they expect it is. He says it's better for Trowa to stay under cover until he has a chance to kill Treize. Trowa agrees.
The colony Quatre threatened has been evacuated, as he appears by it and orders it to surrender or he'll blow it up. The colony decides to attack him instead, and this angers Quatre so much he fires at the colony, which explodes. As Quatre's tears floats by in the zero gravity, he comments that he finds it strange, because he isn't sad at all...
Trowa and Heero gets news about the destroyed colony, and change their course to the next one Quatre threatened. Trowa tells Heero about their orders to investigate, but says they don't have to worry, since it's Quatre they're up against. Heero once again questions Trowa's trust in Quatre, saying that something is wrong with the situation. As they approach the colony, Trowa sends Heero away in another direction to approach the Gundam, while he goes into the area commaning the other forces.
Back in the prison, Duo is optimistic. With Quatre showing up, they'll be busy soon. Wufei is more suspicious, they can't know the new suit is their friend. Wufei also states he has a bad feeling about this.
Meanwhile, Tsubarov cuts the oxygen supply for the prison cells of the Gundam pilots and the scientists, stating Lady Une is too soft, he'll give the orders from now on. In the prison, the professors realise what's about to happen, and mourns all the things they never got to do, such as finish the upgrades on Shenlong. Duo in his cell is angry, he should've been chosen for the mission instead of Heero. Wufei approaches the situation with calm, and continues preparing for when he gets his Shenlong back.
Trowa's group approach the colony, but as no Gundam is in the area, three suits enter it to investigate. In the colony, Quatre is randomly destroying buildings, and as he comes across the OZ suits, he promptly destroys them, and an amusement park that is in his way... After that, he exits the colony, where more OZ forces are waiting. They attack him, and Quatre displays the destructive abilities of the new Gundam. He manages to destroy all mobile suits in the area (except Trowa...), and Trowa is happy to see that this is the best mobile suit so far.
Trowa approaches Quatre, and identifies himself, asking if Quatre can hear him. Quatre says he can hear him just fine, but as Trowa flies closer, Quatre screams at him to stay away, before he blasts Vayeate with his beam cannon, nearly demolishing Trowa's suit. Quatre explains that the he's going to destroy everything insane in the universe, and all the weapons. Trowa is horrified - what's wrong with Quatre? Quatre tells him to tell the others that they should all stay away from him, or he'll have to destroy them all. As Heero approaches, Quatre fires at him, whereupon Heero says he'll kill Quatre.
