Spike complements Twilight well, being cautious, socially confident and down to earth in a way that she often isn't. He is quick to give advice or criticism when he feels that she is on the wrong path, and will often pre-empt disasters before they occur. Indeed he is the classic valet in many ways, devoted and organized, often providing what Twilight wants before she has even asked for it. Despite his tendency to criticize and mock he is extremely protective of his friends, in A Dog and Pony Show he eagerly entered combat against the Diamond Dogs to save Rarity despite them being quite a bit bigger than him.
