Because in the end I LOVE most of the AUs out there so... Pacific rim.
A three pilot Jaeger (similar to crimson typhoon I guess, but in blue colors) piloted, of course by romeo, ben and mercutio. ["cutio did you really had to kick that kaiju?" "yep." "... Good. Because now it's pissed at us! Move those fucking legs you have and run!!!"]
Juliet manage to enter the program in secret and drags her cousin along with her. Despite what everyone else would say their bond is one of the strongest. (they tried other partners too but tybalt was so unstable he could barely connect, and juliet wasn't taken seriously at first, being a woman, young and quite small. Some even called her a distraction. Oh, they show all of them what Capulets can do together.)
Of course, romeo and juliet fell in love, and through the bond is hard to hide things. And tybalt is definitely not pleased. Until the Montague Jaeger arrives just in time to save them. (he's still not pleased... But the nephew of Marshal Escalus is--cute. Kinda. Juliet kept saying he said that, he doesn't remember. He's actually cute, tho. Again. Hiding things is impossible, right?)
But then a really big kaiju arrives and to kill it they give everything. They manage to remain in contact during the whole fight, to fight better knowing exactly what the other will do.
The first to die is tybbs, almost by accident. The Capulet Jaeger start to lose control because juliet, who's screaming and that's all the others can hear, along with her voice calling for her cousin, can't pilot it alone.
Then mercutio, because upon hearing her he reacts by instinct and run to the kaiju to get it away from the others.
Somehow the other three survive, the kaiju is defeated by a third Jaeger that the will only later recognize as the Esxalus one.
Romeo and ben keep fighting, though it's just the two of them, in a different Jaeger that feels cold and foreign. Juliet doesn't. She tried once to find a new partner but she can't help but get stuck in the memories every single time, stuck on the day her cousin died after using their Jaeger shield to protect her and taking all the blow on himself.
It never gets easier, and the day the Montague Jaeger sink at the bottom of the ocean she gives up. (not knowing of the two escaping pods the pilots used just in time.)
In the end there are two broken, abandoned Jaegers in the hangar, whose parts will be used to build and repair other Jaegers, and two friends, or lover, or whatever they were or were not, watching as their most loved ones lives fell apart after their death.
(I'm... Sorry? I guess. I just want my capulets babies being close and cute and juliet dragging him around and them being the only one that can connect with the other. (somehow along the line in the Borgias show "only a Borgia can love a Borgia")
I don't know if romeo will survive or not... I think yes, but.. Who knows.)
Also, the eacalus Jaeger is probably piloted by Paris and valentine I think...
