Meet Purple Strings :3

Purple Strings is a punk rocker chick, whose also an angel pony :3

When she was still alive, she was a punk who enjoyed punk rock and other types of rock music and was an earth pony. However, most of the ponies in her town frowned upon her interests and found her an annoyance, even when she wasn’t trying to be annoying and was genuinely trying to be nice and helpful.

Despite how others treated her, she still tried to remain positive and enjoy her lifestyle.

However, she ended up dying, where she saw a little kid about to be crushed by a falling piece form an old building. She rushed towards her and was able to push them out of the way, but at the cost of the price of building landing on her, crushing her and causing part of her ribcage to pierce her heart, killing her instantly. 

She was then brought back to life as an angel pony (complete with a brand new pair of wings),  and she was told by another angel pony that because f her attitude on Equestira, and for her act of kindness and heroism, they decided to give her a new life as a Angel pony to help others

Although she stas in Heaven, she does like to spend a lot of time back down in Equestira, and she mostly helps out other music ponies, especially ones that are struggling (either musically or personally).
