Race w/out Hyper speed- The Flash wins in the end because Surfer can't use his hyper-speed he will lose to Flash and even to Superman.
To be honest, Sakura did have feelings for Naruto. However it only developed during shippuden. Mashashi kishimoto hints on it when Naruto had finished his fight with orochimaru and was unconscious. Sakura was with captain yamoto and he had told her that he had noticed her slight feelings for her.
Shannarō has no literal meaning, but can translate into Hell yeah!, Hell no!, or Damn it! (depending on the situation). In the English dub, the phrase was replaced by a forceful Cha, which Sakura has a unique way of saying.
