Indigo Wreath

"Indigo Wreath" was a student at Canterlot High who was the owner, or at least the one who walked a blue dog. He was the first human witnessed upon entering the strange new world. He appeared to be an easy going guy, not really weirded out by Twilight's antics. He attended the battle of the bands as an audience member and was under The Dazzlings curse.

He may have related to Caesar as the two have remarkably similar appearances and have been seen walking the same dog.

History
Indigo was an athlete who played in various school sporting events, such as a tennis, soccer and finally golf game against Crystal Prep Academy alongside Mystery Mint and Cloudy Kicks - all of which he lost.

He was the first students who saw when she first entered the human world, though he just shrugged when he noticed how weird she was acting.

When Sunset Shimmer tripped on his dog leash, Indigo helped her up and made sure his umbrella was over her.

He is a member of the Art club and painted abstract paintings.

Personality
Indigo has been shown to be very kind, friendly and easy-going. He helped Sunset Shimmer up when she fell and offered her room under his umbrella and supported Aqua Blossom when she was hurt during the Midnight Sparkle incident. He tends to be relaxed, rarely getting caught up in the antics of the school and tries to help others. He appears to be close with his dog, whom he walks to school.

Naming
The closest thing to an actual name Indigo has ever been referred to as was "two-legged creature" by Spike. On r/listofponies, it was decided his name would be listed as "Indigo Wreath", though other suggestions included Roman and Ivy League.
