Telepathy was famously portrayed by Aquaman, though not in the exact form that the term was later connected to, as he could just mentally communicate to marine life. It was popularized by heroes such as Captain Comet and Martian Manhunter, who had what could be known as 'true' telepathy. Telepathy, put as basically as possible, is the ability to read the thoughts of, and to mentally communicate with others. As time moved on, telepathy grew more and more popular, introducing prominent characters such as Jean Grey, Professor X, and Psylocke. As stated previously with Aquaman, other forms of telepathy include being able to communicate with animals, or more specific groups of animals (such as insects with Ant-Man or reptiles with Lizard).
