Rosalina & Luma - Defensive Wall

Rosalina controls Luma, and they work together in order to fight. Rosalina can shoot out Luma and bring it back, leading to some interesting neutral and attack strings. Luma itself can take damage for Rosalina so it's best for Rosalina to use Luma defensively. Once Rosalina knows how you like to play, its hard to get in. She however has a large hitbox, and is very light.
