Rosalina & Luma
These two being as powerful as they are came as a bit of a surprise. Rosalina glides her way across the battlefield like the Star Princess she is. And while she is by no means the epitome of speed, she is certainly a solidly maneuverable character. However, what makes her considerably strong is just how hard she hits. Her attacks and smashes have a decent amount of range and some serious launching power.
Luma fights alongside Rosalina and tends to reciprocate some of the moves that she herself makes. The most standout move that Rosalina and Luma have, however, is the neutral special. Assuming that Luma has been called back to Rosalina’s side, Rosalina can charge Luma up and shoot him a pretty good distance forward. The move is deceptively powerful and, at full charge, can launch an opponent off the stage at a mere 50%. The full charge occurs fairly quickly and would be spammable were it not for the fact that Luma needs to be reeled back in to Rosalina’s side to use it again. But even then, calling Luma back is a quick process.
Rosalina’s recovery is alright, albeit a bit difficult to control, and her Final Smash leaves much to be desired. But despite these flaws, Rosalina and Luma can get a lot of work done through their fairly simple standard and special moves. Rosalina and Luma are, interestingly enough, not amazingly powerful or unique when considering their capabilities at an individual level, but holistically, everything comes together in a very powerful way.
