Her name is Lovenote Tango, but everyone she knows just calls her Tango.
 
She’s a very upbeat pony,has a peculiar sense of humor, almost always in a good mood. A bit of a stallion chaser.
 
Tango is a former resident of the mining and nearly sub-terrain community of Hollow Shades, making her a rare instance of a pegasus who is used to confined underground spaces. But at some point she moved to Cloudsdale, made friends there, and joined the Chariot Pull Team, the Drumfires. While she is built more for speed, she is stronger than she looks, and enjoys the challenge of performing well with the extra weight of the chariot.
