Hypnos/Somnus= Sleep and Morpheus/Somnia: Sleep and Dreams

-Wings of Slumber: Has retractable wings they can use to fly with. People who look at them will be slightly swayed, distracted, even wanting to go to sleep.
-Sleep Charge: when their physical bodies are injured, if they have put opponents to sleep, their recovery rate and regeneration speed up dramatically. When they themselves go to sleep, they heal faster.
-Last Sleep: Can drain the life force of any opponent they have put to sleep.
-Master Hypnotist: Able to hypnotize people with their eyes, voice, or touch, but only on those with minds weaker than theirs or those who let them.
-Lethe Blessing: Are immune to the effects of the River Lethe.
-Poppy and Opium Master: Can summon and use opium. Can summon a field of poppy that put people to sleep

+Morpheus= Sleep and Dreams
-Worst Nightmare: Can make an illusion of their opponent's worst nightmares appear, only works on one person at a time.
-Dream Charge: when their physical bodies are injured, if they have put opponents to sleep, their recovery rate and regeneration speed up drastically but will depend on what dreams they give their opponent.
-Last Nightmare: Can drain the life force of any opponent they are giving nightmares to, the more horrific, the faster their opponent's life is drained.
-Dream Demon: Can summon their shadow as an apparition that fights with them, appearing as their opponent's worst nightmare and their allies' wildest dreams. Able to use on multiple enemies at once.
-Dream Vision: Can see the last dream of anyone they look at.

Both:
-Sleep Induction: Able to drain an opponent's energy, which puts them to sleep, through touch.
-Aura Of Relaxation: Always emitting an aura that makes others sleep. Can differ between allies and enemies, as allies will be relaxed enough to enable them to be able to think more clearly, and enemies will be drowsy and sluggish, weakening them.
-Oneiroi Companion: Can summon their Oneiroi counterpart from within themselves, use its powers, or see through their eyes.
-Astral Master: Can astral project. Cannot physically attack other beings with their spirit forms while projecting, only see, hear, and smell. Spirit-self doesn't feel any pain or exhaust from their physical bodies while projecting.
-Sleep Steroid: Since their bodies are asleep, their spirit-self is supplied an endless amount of strength. The physical attributes of their physical bodies also increase, but how much depends on how much power they've built.
-Astral Command: Can control their own bodies while astral projecting as naturally as if they were still in them. If the user is doing using Astral Command, you wouldn't even know or be able to tell because they're moving their physical bodies so naturally, unless you see their eyes, which are close, or try and talk to them, which they can't because they're asleep. Does not use any power at all.
However, their physical bodies still get exhausted, even with the physical boost from Sleep Steroid. The user will feel whatever physical exhaustion or pain their body has got while they were "out" when they stepped back "in".
-Winds Of Som: Can summon and control Winds Of Som, a type of wind that can put different aspects of a being to sleep temporarily, like senses, body parts, memories, and emotions. (when it's the senses, the target will become blind, deaf, unable to smell, feel or taste. Body parts mean the target won't be able to move them for a certain amount of time. Memories mean they will temporarily forget whatever the wielder wants them to. Emotions mean the target will be unable to feel whatever one emotion the user wants)
-Shadow Travel: Able to shadow travel since their father is a descendant from Nyx and Erebus, but is in short distances and, therefore, is easier to use.
-Astral Regen: Can use some of their astral power to heal injuries on their physical body.
