Now this is a battle of top tiers! Both of these fighters are near the very top of the Smash Bros roster and they share many of the same advantages. Both of them have a large arsenal of attacks at their disposal and super speed is an ability that they possess. Greninja can try to overwhelm Samus with his water abilities, but her armors can stand up to just about any element. I can see Samus pulling ahead in this round thanks to her Zero laser, but it will definitely be a close fight that could go either way. Samus wins.
