Dragonaut: The Resonance

Many similarities with Dragon Crisis except that it's a more older version , both involve dragons, the main character is attached to his dragon which is a girl. Also the dragon girl saves him when they first met. 

Similar idea.. boy meets a girl who's not a human. dargonaut and elemental gelade both are about people who turn into fighting machines... 

well its actually both this and r2 the main character and his best friend developed from best of friends to the worst of enemies 

The female main character is in a way similar, and there is alot action in them, but the main reason might be, similarity of the character styles. i recommend both, dragonaut has a light style, while blassreiter has dark style to it, but for you to think more than boring of these serie, you have to watch more than one episode. 

atleast the first half of Dragonaut will remind you of Melody. 1. they ride machines, that have a human form. 2. the riders have a special bond with machine 3. the protagonist's lover gets captured (first half of Dragonaut) 4. the lover is condemned to fate forced away from protagonist 5. they go in space 6. the lover has pink hair sorry for spoilers, and Dragonaut's machines are dragons not machines, i think, they kinda look like machines though 

wow on the first episode i saw of tis i automaticaly thougt "wow this is VERY CLOSE to dragonaut :the resonance" ex.thye both have some people in outerspace that "fight" aginst the earth ppl with mecha,faanservice,"alien" like people i swear its a good match 

both are the same because the main characters have special links or bonds between him and the person they are linked to, which help in fighting enemies and making allies. 

Both have mechas to fight with. (Dragons- in Dragonaut and AHSBM units- in Majestic Prince). Both have to fight enemy from unknown race. Both are set in space  

Both anime explore the idea of collectivism for the common good and it's effects on individualism. 

Both shows feature high concentrations of fanservice and prominently include relationships, both friendly and otherwise, between humans and dragons, as well as several of the secrets being the state of their worlds. 

Both Anime Has the Same Type Of Story But Different Ending, In Gin-Iro No Olynsis The Earth is Being Attacked by Gardeners(Creatures From the Moon) That Trying to Erase the Remaining Human Kind and in Dragonaut the Earth is Being Attacked by the Thanatos(Giant Dragon) That Roam Around the Universe Destroying planets that contains its Dragon Egg's. In Gin-Iro No Olynsis The Girl Main Character can Transform into a Robot and Can be Piloted Only by the Chosen One. In Dragonaut The Girl Can also Transform into a Dragon and Can be also Piloted by there Resonance.  

Dragonaut will remind you Eureka Seven every moment while watching it. We have mechas, we have a newbie boy and experienced girl as a main characters, we have great airships, we have crazy enemies and we have a problem with the destruction of the Earth. 

Well lets say both of them are really interesting to watch. While Asura Cryin is more like a Mecha/Robot Stuff, where dragonaut is about Dragons. Well lets say they are kinda the same because Both of the Main Girls in Both Anime's are able to transform into a Robot(Asura Cryin) and Dragon(Dragonaut). The both Main male character's are the one who's piloting the Robot(Asura Cryin) and Dragon(Dragonaut). There is also some Romance, but Asura Cryin has less Romance than Dragonaut. 

The yuri-licious possibilities* of the master/servant relationship Dragons have to their (usually) same-sex Masters may make Dragonaut ~ The Resonance appealing to Mai-Otome fans who enjoy slashing Meisters and the person they've contracted with. (Or Meisters and Meisters, for that matter.) Compelling cast and story; lots of fanservice, but more subtle and less distracting than, say, Godannar. * For the same reason, may also appeal to yaoi fans, with the bonus that character designer Makoto Uno mostly succeeds in making the male characters as sexy as their female counterparts. There's something for everyone here. :D 

they both have a child(hime) and dragon(dragonaut) and if the child die someone will die something like that ^^ 

You have the same fighting to save the planet from Alien invaders idea. You also have a love triangle, although not as clearly defined. It gave off the same feel as Macross Frontier.
