Fluttershy

When Fluttershy is first introduced in the series, she barely manages to tell Twilight Sparkle her name on account of her timidness, whispering so quietly that Twilight can't hear her, and even going so far as to shying away behind her own hair. However, she immediately becomes enthusiastic when she sees Spike, imploring the baby Dragon to hold a conversation with her, which he ends up doing, and follows him and Twilight all the way to the library. Her shy nature contrasts with Rainbow Dash's abrasiveness, most notably in Dragonshy, and to a lesser extent in Sonic Rainboom. What is noticeable is that throughout season 1, Fluttershy's inability to speak up often annoys Rainbow Dash, and Rainbow expresses her aggravation more than once. One instance is when Fluttershy produces cheers to the best of her extent for Rainbow Dash at the beginning of Sonic Rainboom, none of them coming close to being loud and encouraging, much to the latter's dismay. Season 2 shows them having grown closer to each other as friends despite their differences. Voice: Andrea Libman.
