I decided to draw Rainbow Dash with Thunderhead, an OC I made for her to be her husband in my "Flurry Heart's Story" sequel fanfiction. They meet before the end of the show and start dating and are married some time after Twilight's coronation. At the time FHS starts, they already have three kids and Dashie has quit the Wonderbolts to become a stay-at-home mom while Thunder works with weather patrol ponies for Ponyville. Thunder's a very supportive husband and dad. He enjoys Daring Do just like Dash does and has always been a huge fan of the Wonderbolts. Their oldest son, Storm Streak, becomes fast friends with Flurry Heart at some point in the story and goes on adventures with her, the Cake twins, and Applejack's twins.

I know it's an OCxCanon pairing, but I just love these two and I'm so happy with the reception that Thunder has gotten! :)
