I write Telepaths, and gave an example above of one.
Let's take 4 DC telepaths to change it up some.
**Saturn Girl**
Saturn Girl specializes more in Psychotherapeutic aspects of Telepathy. She is Highly skilled in Mind Reading, understanding Emotions, Probing deeply into the Minds of other people at a faster rate of speed, using Illusions to great effect. Ability to calm single or Large crowds, prefers to use Sleep, Calm, techniques, rather than harming the brain. She provides the team with quick and in depth information. Her Telpathy as far as Mind Reading and Communication extends to animals, and aliens with no ill effects. Plant Suggestions in weak minds. Detect Mental Life, Etc. She's got a ton of feats if not raw power.
She's a bit weak on attack, but is able to last long enough for help to arrive, as she is mind linked constantly to the team. Usually the Linchpin for victory, which is why she is Leader so often. Tactics is her thing. She'd be Pre-Ninja Psylocke without the Psychoblast.
**Saturn Queen**
Saturn Queen understands the mind in so far as Mental Domination. She's got VERY weak Telepathic attacks, but is able to Mentally control almost anymind, and has even almost defeated Saturn Girl by going after her mind, but Saturn Girl is a prodigy and able to repulse the attack. Saturn Queen Probes minds only so far as learning about personal gain. She never uses mind links, and is very "selfish" with her powers. She can read minds, but not as many or as fast as Saturn Girl. She's got a lot of Raw Power but limits herself to basically being a master Puppet Master. mentally enslaving large groups of people. But lacks the versatility of Saturn Girl. She's Emma Frost, a master manipulator.
**Esper Lass**
Esper lass has DEVASTATING Mind Blasts and mental attacks, she is almost always in attack mode, crippling and disabling her foes from range, and showing no ability to control minds, even though she can read a couple minds at a time. She doesn't probe minds, control them, or trick them, she just reads and attacks. she defeated Saturn Girl once because Saturn Girl was unprepared for her attacks, even though her shields held for a time, Esper Lass just brute forced her way in.
