Only one mimic a hero might come across in a circus full of them (shh, don't worry, it will be ok), the taming mimic is an offshoot of the stump mimic. It carries an innate ability to communicate and control animals. However, the taming mimic does not make friends. Instead, it commands fear from the beasts under its shadow. Whether a lion tamer's whip or a beast master's scepter, the mimic dominates the wills of simple animals as directed. Though it is capable of doing so without someone holding it. As such, it's developed a cruel streak that a proper circus would abhor. It views show animals as things to be exploited and then either discarded or eaten. Oddly, this perspective doesn't extend to humanoids. Oh, the monstrosity will still certainly eat them for nothing gets in the way if it's hunger. As is often the case, however, a bully is afraid of those who bully them and the mimic cowers under the thumb of the circus members who employ it.
