Star Struck is a very vain young stallion, he is constantly paying attention to his looks and buying the newest clothes, hair products and accessories, he refuses to leave the house unless he looks his absolute best. Despite this he is very elegant and kind hearted. He is very cowardly and whimpy for the most part and cannot handle much.  
He is a very fast runner and can beat pretty much anyone in a race, but unlike his mother and brother he has no interest in racing as a career, he only does it for fun, once in a while he does enter small competitions though  
He works for Rarity as a fashion model, he loves to crossdress  
He is very close to Fluttershy’s daughter, Sunshine, they are best friends.
 
Goldrush is a rude, spoiled brat of a stallion who cannot stand when he does not get his way, he’s very conceded and overly confident, has no manners and loves to pull pranks, especially on the servants of the castle (Blueblood had Rainbow Dashes cloud home reconstructed into an even larger castle to fit his royal needs). He tried serving for the weather team in ponyville but was kicked out for not following rules, so he spends most of his time joining, and winning, small and large races, he does not want to join the Wonderbolts because there are too many rules. Like his mother, he’s a very talented flyer, although he has yet to make a sonic rainboom.  
Despite all his bad qualities he has a few good ones, Goldrush is funny and sassy, he knows how to make others laugh, he’s also a lot of fun to hang out with because of his adventurous, carfree spirit.  
Goldrush is obsessed with diamonds, gold, gems, and other metals and stones, and likes to go hunting for them in his free time. He has a huge collection of them.
