Ever since Valkyrie was teased before the MI transition, I knew I had to give her a flying horse to ride. Technically, Aragorn is not a pegasus - he is a genetically modified horse. Dane Whitman's uncle, the first Black Knight, was a villain who was also an expert at genetic manipulation. He genetically modified a horse to have wings and to fly. The criminal Black Knight's horse (the original flying horse) mutated further into Hellhorse and became the mount of Deathknight. I guess there's just no reforming an evil horse.
Dane Whitman used the process to create a second flying horse. Black Knight left Aragorn in the care of Valkyrie while he moved temporarily to live in the Middle Ages, but the companionship of Aragorn and Valkyrie ended up being permanent.
Aragorn's recipe is simple - the World Peacekeepers brown horse, repainted (available at Big Lots now in my area) and Angel wings. These are the 6-pack Angel wings repainted to match the horse.
Duplicolor took care of the brown, but I added shadings and some grays because no horse is truly white - and this is a warhorse, not a show horse.
There are a few other horse options out there. The articulation is just so-so on this one. The rear legs are not jointed below the hip and the tail is immovable hard plastic. The bridle and saddle are also cheap feeling. But it is inexpensive! There is also a Prince of Persia black horse - it is better, but will cost more. The Raiders of the Lost Ark horse is already white, but is undersized for this figure IMO.

I also modded Valkyrie by adding a spare Black Knight cape (and painting the metal silver to match her):
