The Foci Of A Tag: Elemental Manipulation, Invulnerability
Invulnerability appears in 7 powersets we have so far: Steadfast, Antaeus, Frostbite, Golem, Lightstep, Man'O'War, and Zeno.
Invulnerability is mostly the "has durability" keyword. It covers all sorts of defenses.
Steadfast's version is the most simple: He's the toughest man alive and unable to be harmed. Antaeus is similar, but with a weakness of having to be touching the ground. Lightstep could also do so and become invulnerable, albeit only for short bursts while his speed was active.
Man'O'War is the type with enhanced durability, which was dependent on how many arms he had manifested, scaling up with more.
Meanwhile, Frostbite, Golem, and Zeno instead had armor made of another of their abilities, from ice, to stone, to compressed space.
Elemental Manipulation is both highly varied and highly simple. It's the manipulation of a specific part of the world. Most of the differences revolve around specific variations, and the difference between manipulating existing elements vs generating them, or both.
Hydrocity creates water, but can't manipulate it.
Frostbite generates and controlled ice.
Deadman, upon dying, would be able to generate and manipulate magma/lava.
Golem manipulated rock/stone/dirt/gravel/concrete?, but had to find it instead of generating it.
Feth Faida manipulated and generated mist/smoke/fog.
Umibozu manipulated water, but couldn't generate it.
Automne manipulated wind/air. As it's literally everywhere around us, generation isn't a problem.
Novalight generated light and radiation. (I'm not sure which was the Element and which was the Energy, though.)
