Every one wants Zechs, everyone likes Zechs, everyone has a crush on Zechs

Treize Khushrenada He claims that he is the best friend of Zechs, according his aristocratic soul, this may as well mean, he is the best person who qualifies to love Zechs. Being Zechs' superior, he has helped Zechs in various ways, from sparing Relena's life to staging a war for Zechs to escape the judgement of the alliance. What makes it so obvious that he loves him? In the near ending part of GW, Zechs once again stood up to the world as the leader of the White Fang, and Treize, in no time, came out from his vacation to take the place of Relena on earth (thank god! how can they let a little girl like Relena lead the earth, ridiculous ...), just to be in Zechs plan! Later on, in space, Zechs refused Treize's challenge for a duo and wanted to kill Treize with Libra's main weapon, Treize didn't try to escape a bit, just wishing to be killed by Zechs! Being killed by his love, what a way to die! However, at the last moment Lady Une came from nowhere and kicked Treize's mobile suit away, ruining the moment. Having planned to die in battle already, Treize has to find his second best choice, Wufei, to kill him. How can Wufei compare to Zechs? Poor Treize, being killed by this sexist who knows nothing except fighting ... Treize's last wish of meeting Zechs in the other world marked the glory-less-ness of his death ....
Relena Committed to total pacificm, and logically to family values, she has to love his only blood brother left in this world ... Even though Relena always questions Zechs' action whenever it is war related, Zechs never ceases to pave the way for Relena to be a total pacifist, how touching! Relena should just break down and cry, instead of challenging her brother's motives, annoying the audience.
Quatre and Trowa These two are too busy playing musical instruments together that they don't even notice the earth is revolving around the sun. But we know they admire Zechs' superior ability, be it piloting the MS, programming the MS system, saving the world secretively, etc, something that no one else can accomplish alone.
Noin Follower of Zechs from the very beginning (back when they were in school together). She is willing to sacrifice any time for Zechs, she is willing to follow Zechs even if she thinks that his actions are out of line. My favourite female character in GW! Noin probably understands Zechs better than anybody except Treize, who can understand him from an aristocratic and idealistic point of view. No one can understand this fallen prince unless they have been through something as traumatic as Zechs has been through.
Heero Definitely not a follower of Zechs but he has been following Zechs as long as GW runs! In the first episode, he was defeated by Zechs and had to abandon his MS. In the last episode, Zechs saved his life by preventing him from self-destructing. And not to mention all that happened in between! In every battle with Zechs, Heero's only target was Zechs. He kept emphasizing everytime that he was the only one who could stop Zechs, he would assign responsibilities to other pilots (e.g., ordering Quatre to monitor and control the battle using the Zero System), and then went straight to where Zechs was residing. From the audience's point of view, Heero was just trying to get to meet Zechs, isn't Heero obsessed with Zechs? Obsessed with winning the duo he thought, but subconciously, Heero just wanted to spend time with the handsome blonde prince!! At the end of GW, Heero was trying to save Relena and return her safely from Libra to earth, what did he say about helping Relena? He said that he didn't want to owe Zechs a favour, after finding out that Zechs is paving the way for Relena's reign, so after all, Heero was doing everything for the sake of the prince.
Wufei This seems to be the least politically correct guy in GW, calling the female species woman, despising the weak, and insisting that he can fight alone and need no friend. Despising the weak as he does, Wufei must have a strong admiration for the strong, that's why he loves to go after Treize for duo from time to time. Zechs, being such a powerful figure on earth and in space, must have drawn a lot of attention from this politically incorrect guy, of course, being so cool, Wufei has to hide whatever feeling he has for the prince!
Duo Duo seems to be chasing after Heero all the time, and Heero was always after Zechs, so indirectly, Duo is after Zechs too ... Dorothy Dorothy seems to be a royalty hag. She likes to be around Treize, her grandfather, and the Peacecrafts, and later on just became a nuisance for Relena and Zechs. She may know something about war and strategy, but she should have been grateful that Zechs actually allowed her to fool around in his battle, such an important battle, such inexperience from a youngster that must have reminded Zechs of his sister. Otto Remember Otto? The guy Zechs made responsible for the restoration of Tallgeese. Flying the tallgeese alone broke this poor guy's ribcage already, but after seeing that Zechs himself got hurt too on this powerful MS, Otto decided to sacrifice himself in order to serve Zechs and Zechs only, not OZ or the alliance. Lady Une It is highly unlikely that this woman will hate whatever her superior loves, she's obsessed with Treize to the point that she'll follow whatever path Treize chooses. Others Who else can you think of?
