The Aspects take many forms both subtle and overt. Pumpkins, shaving cream and rays of light are all expressions of one Aspect or another. When gods and prophets go to war, however, they frequently employ a purer form of their Aspects, one I’ve taken to calling Elemental [Aspect], a shapeless energy field of tremendous power, unique in nature to each Aspect.
Elemental Time: The Clockwork Majyyks (https://www.homestuck.com/story/4043), a twisty, spiraling technicolor power wielded by the Handmaid, a Witch of Time, and later Jack Noir when he is infused with the essence of Lord English.
Elemental Space: The flames of the Green Sun. Kind of obvious, but come on, it’s a torrent of green fire formed from ignited spacetime.
Elemental Breath: The Breeze. Again, obvious. Wind given shape, color, and occasionally solidity by the power of the Heir of Breath.
Elemental Blood: The Red Miles. Never wielded by a Hero of Blood, but as a semisolid crimson energy emanating from a symbol of duty and expanding into the shape of branching blood vessels, it seems likely.
Elemental Heart: Soul-rending lightning (https://www.homestuck.com/story/6745). Probably not soul-rending in the hands of a non-Prince, but the lightning theme seems pretty solid for the intensity of the Heart Aspect, especially with
Elemental Mind: Neural electricity (https://www.homestuck.com/story/7956) Terezi uses Elemental Mind more to perceive alternate timelines than as a weapon, but the neuron pattern is consistently associated with her and the tamed electricity works well as a contrast to Dirk’s lightning.
Elemental Light: Pure Light (https://www.homestuck.com/story/6832). A bit on the nose, perhaps, but Rose weaponises Light well with the skills she learned as a Void magician. A similar energy surrounds Vriska when she initiates her Ancestral Awakening. (https://www.homestuck.com/story/3825). Varies in color from white to blue to purple.
Elemental Void: Stabby Darkness (https://www.youtube.com/watch?v=Y5wYN6rB_Rg&t=3m18s) Only really seen in Collide, Roxy’s darkness tendrils resemble the Void symbol in shape and fit right in with John and Rose’s similar elemental attacks.
Elemental Life: Raw Aura (https://www.homestuck.com/story/4408). Elemental Life is unique in that it conforms to the text color of the user, Jane’s is pale blue while Meenah’s is Fuschia (https://www.youtube.com/watch?v=Y5wYN6rB_Rg&t=10m52s).
Elemental Doom: Hithertoo unseen, unless you count Sollux’s red/blue psionics (questionable).
Elemental Hope: It’s the big yellow Hope field. I mean duh.
