Her Neutral Special is strange, the charge shot is the archetypical Smash Bros charged projectile, and everyone recognizes it as coming from the Metroid games, but taking a closer look, it’s bizarre how off the move is from its inspiration.
In Metroid, the move is a more passive part of Samus’ arsenal and it’s typical for players to have a charge shot ready as they traverse alien planets...
In Smash, it’s a move that you have to stop and charge fully before you can move with it. In Metroid, the move can be charged decently quickly to get an average sized orange ball of energy. In Smash, the move takes much longer to charge and the energy ball is huge and the wrong color. In fact, the move in Metroid isn’t even called the charge shot it’s called the charge beam.
