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 aren't afraid to speak out for what is right, even if it challenges the warrior code. They are determined to show what is right, though sometimes that can get ahead of them and lead to stubbornness in them. They generally do try to present themselves as a peaceful clan, however.
