A New Purr-spective (Mario Bros AU)

Two twins, growing up with only themselves to rely on. They have been to literal hell and back for eachother and the sake of their friends and kingdom, and neither can imagine their life without the other.

Mario, the older, more confident twin. He is the hero known all over the kingdom and in many others as well, and has a reputation of the fearless hero to uphold. He appears outgoing, fearless and confident on the outside, but is constantly stressed and fears for others in bad situations on the inside, his mind still holding guilt from his past attitude and the way he was to his brother before he saved Mario from the mansion.

Luigi, the younger, sweet, scaredy-cat twin. He is the over-looked brother, still a hero in his own right, but not remembered or praised as much. This suits him for the most part, attention isn't something he cares for, but it does hurt when his brother gets main credit for his actions, and his screw-ups are noticed more than his skills. He's the jumpy one, always having to face his fears, that struggles to see his own skills, even when they are pointed out. Despite being jealous of his brother, Luigi loves him even more and would always want to stand by his side, though he often worries he is just making life harder or is bothering his friends and brother.

So, what happens when one is forced to face the worst situation they could imagine? When an odd magic occurance during battle forces the two into an odd situation, how will they handle it? And will they learn how to work through each of their issues, or continue to hide the worst of them.
