These are all straight from the worm wiki, but it's pretty well detailed on what the different abilities are.

Mover- A mover has the ability to transport themselves and/or others to other locations, by means of enhanced speed, teleportation, flight, vehicles or the like. PRT typically appends the mover classification with the specific type of capability, eg Mover: Teleporter.

Shaker- A Shaker can affect a broader area, asserting some degree of control over the battlefield.  May include gas, explosions, forcefields, and ambient or radiated effects. Most wide-area-effect, forcefield and spacetime manipulation powers fall under the Shaker classification.

Brute- A Brute classification typically indicates enhanced strength or durability, capes who are most dangerous in a melee and are typically very difficult to put down.  While the execution may remain fairly stable, the source of this power can vary.

Breaker- A breaker is those who have some ability to ‘break’ the natural laws of the universe as far as those laws apply to them. This is frequently a side effect of powers to prevent them from harming their owners. They typically have the ability to alter themselves to a different state in which they maintain different abilities.  Appends other powers, but only in this state.  Can also include general altered states.

Master-A cape whose powers let them control others or create minions (be they humans, parahumans, animals or specific objects). Can range from ability to control simple insects all the way up to superhuman/projections. Varies from area (touch to long distance), number of beings affected (one being to nearly infinite), simple commands to absolute control and across a spectrum of time lengths and programming (short durations vs. indefinitely or programmed commands). Can be of pseudo-telepathic variety (there are no true telepaths except for the Simurgh) or require voice commands. The PRT typically designates Masters as the second-highest threat in any situation.

Tinker-Covers anyone with powers that give them an advanced grasp of science. Lets them make technology years ahead of its time. They can intuitively create or alter many devices beyond the usual restrictions of knowledge, resources and physics. Tinkers are less dangerous when removed from their gear, but should not be assumed to be harmless.  A typical tinker can artificially assume any number of other classifications, depending on speciality. Speciality should be appended to the classification in every case possible. Many Tinker devices cannot be maintained or used safely by anyone except the Tinker in question.

Blaster- A cape with ranged, offensive attacks of some form.  Can include blasts, thrown or moved objects, grenades.  Not always damaging, but generally deleterious.

Thinker- Possesses enhanced knowledge, skills and/or perceptions beyond any reasonable norm.  Includes clairvoyance, precognition, skill acquisition, enhanced hearing and enhanced sight.

Striker- A cape with the ability to apply some effect by touch or at point-blank range. Has a power that applies on physical contact.  Often applies a changed state, like the breaker classification, but isn’t personal.  Melee range, including strength only without any durability, else it is classified as a Brute power. The striker classification could include certain Breaker effects as they were applied to things other than the cape themselves, but not always. Other strikers included those who used energy weapons, those who had certain kinds of superstrength that weren’t accompanied by durability and those with pyrokinesis or such that didn’t extend more than a foot around them.

Changer- Can alter their form, appearance, and/or natural abilities through some manipulation of their bodies.  Does not include new powers beyond natural weapons, armor, or durability.

Trump- Can manipulate powers in some capacity, altering, granting, strengthening, weakening or removing them entirely, or has powers that interact solely with the powers of others. Can have different powers or effects based on circumstances.
