Rainbow Dash v.s. Russell Edgington
Rainbow Dash, Equestria's premiere athlete and patron of coolness, awesomeness, and ofcourse, radicalness, comes across a particularly rude man with pointy teeth harrassing Fluttershy.
This, unsurprisingly, upsets Rainbow Dash, who goes about confronting him at nose-to-nose-stare-of-doom range.
Fluttershy, sensing that things are about to get radical dons her best cheering outfit and "yays" to the best of her ability. From within her home.
This is current, end of Season 2 Rainbow Dash who has shown to be able to replicate Rainbooms on command.
Her Filly-Dash feat is counted for this thread.
