A line-up of the first-born children of my royalty next-gens in order from eldest to youngest.
From left to right:
Princess Flurry Heart
Species: Alicorn
Parents: Princess Cadence, Shining Armor
Aqua Iris
Species: Unicorn
Parents: unknown - adopted by Twilight as a foal
Prince Apollo
Species: Alicorn-Sphinx hybrid
Parents: Princess Celestia, Prince Scorpan
Prince Amour
Species: Unicorn
Parents: Prince Blueblood, unknown mother
Prince Pyrinos
Species: Unicorn-Umbrum hybrid
Parents: Princess Luna, Sombra
As Aqua Iris was adopted by Twilight and Twilight herself never has any children, I consider her part of the line-up even though she does not inherit the title of Princess. Also, despite the fact that in my nextgen universe Tempest and Twilight end up together, I do not consider Victory Vale to be true royalty and thus did not include him in the line-up.
