Basic Information: They are a sub species of Pegasi that have developed a resistance to harsh chemicals and lightning. They can touch rainbow mixture without side effects. They have a resistance to lightning hence the name "Thunder Ponies". More information will be in the Ability section
Appearance: This pony species unlike many other have a distinct mane/tail shape. The mane or/and tail always has a lightning shape at the end of their mane/tail style.
They also always have different coloured hooves, they are irremovable marks and can co in different shapes or colours. The hooves' colour are normally a darker colour compared to the coat. The marks can also be anywhere else on the body.
Their wings are also a different colour to the coat, and can be in full colour or shades.
Being a Thunder Pony isn't just a name, they have a role in Equestria to clear out dangerous fumes, clouds, and thunder storms. With generations of evolution they have an immunity to dangerous environmental hazards, but in the process leaving marks on their bodies.
They have the ability to be struck by lightning many times without damage (but they have a limit). Many Thunder Pegasi become extremely strong fliers that are able to handle extremely dangerous jobs and do them quickly.
Mainly found in Cloudsdale as well as danger zones to keep the weather under control. Some Thunder Pegasi move to different cities to follow their dreams and to see where their cutiemark leads them too.
