Rainbow Dash is a female pegasus and one of the main characters in My Little Pony Friendship is Magic. She is responsible for maintaining the weather and clearing the skies in Ponyville. She dreams of one day joining the Wonderbolts. She is the only pony to be able to do a Sonic Rainboom, but this doesn't prevent you from being able to do one with portals. Rainbow Dash has a pet tortoise named Tank. She represents the element of loyalty.
In Mari0, while she herself does not appear, her mane and ear is the 33rd hat that you can wear in the game. You can wear Bestpony by going to the character customization screen, but you will also recieve it after preforming a Sonic Rainboom once you enable your ability to do so by completing world 8 of SMB.
In Mari0: SE, Rainbow Dash reached playable character status. Maurice has livestreamed him coding flight and actually playing as her. MM102 also made a Rainbow Dash character, which was later included in beta 9, although her flight ability was removed.
- One of the game's loading texts is "Raising coolness by 20 percent.." in refrence to her catch phrase that she only said twice (once during a hot topic video) which got picked up when she said her dress needed to be '20% cooler' without saying specifically how to make it cooler.
- She is apparently a natural born flyer, even as a human, as seen in Equestria Girls when an alternate dimension human replica version of her flies as soon as she gets wings, despite never having wings before then. She could also fly in Mari0: SE, but this was removed in beta 9.
- The hat based on her mane is called 'Bestpony' in Mari0's source, probably because Maurice thinks Rainbow Dash is the best pony.
