Thunderclanners tend to have lighter pelt colors, such as light browns or creams. However, you can occasionally spot cats with darker shades of browns as well. Tabby patterns and thick fur are also quite common among them. Thunderclanners also appear very well-built and burly, adjusted to the prickly undergrowth they commonly hunt in.
Thunderclanners are incredibly hostile towards others not apart of their clan, being quick to lash-out when threatened. They are still very stubborn and aren't ones to change from their controversial ways. Despite this, they are extremely brave in battle, using fierce fighting techniques to easily overpower their foes. Thunderclan cats are also intensely loyal to those they love.
