Wheat Leigh is a studious, dapper-looking
Pegasus with a white coat and gray mane and
tail, though that is to be expected due to the
black-and-white noir shift. Ironically, once the
color is restored, his coloration does not change,
nor does his outfit. “I tell you, I know what I’m
about,” he’ll chuckle. He speaks with a soft
British accent, is somewhat cynical in personality,
and is easily startled. He wears a dark gray
overcoat and a matching fedora.

Wheat Leigh loves the science and magic of
motion and transportation. He has spent his adult
life in joyous study and pointed experimentation
in the name of furthering everypony’s mobility.
So what if a Pegasus doesn’t typically learn
Magical Studies? Wheat so loves the subject, he
is determined to someday master long-distance
teleportation through extensive use of specialized
mechanized transference systems. In short…he is
a portal nerd.

Wheat Leigh is fascinated with portals and
thinks it’s finally his moment to shine! He can
figure out the mystery of the changeling portal
and do his part to save Equestria. Everypony will
be so impressed that maybe they’ll make him a
Professor of Portalism! Portaling? Portal Ponies?
We’ll workshop it!

Wow I wonder who this guy's a reference too. Despite his color palette apparently being naturally gray-scaled and not changing after color is restored at the end of this chapter, his eyes are noted to be a "beautiful, blazing blue". You can probably imagine what the exact color is.
