Just been thinking about how characters from Sentinels of the Multiverse don't always tend to be 'alive' in the way we understand it. I was thinking of gathering a list, as my own reference/amusement.
Ones I can think of, off the top of my head:
Any others we know of?
Medico and Writhe fall into this to me to a degree moreso Medico being pure energy. The Operative gets resurrected like Fixer and who knows what her status is.
Omnitron.
Haka. (Does he even need to eat and sleep?)
DW Nightmist, she's almost all mist.
Doctor Medico, he's all energy.
The Idealist. Is she alive in a legal sense? How on earth did Dr medico adopt her?
Progeny. What even are they?
Biomancer.
Citizen Winter was pronounced dead at birth and doesn't't breathe
"Aliveness" in the Sentinels verse seems to revolve around the twin ideas of sapience (re: stuff like how discussion of what beings could become a Virtuoso seems to revolve around sapience and what counts as being sapient) and some sort of nebulous idea of the "soul" (re: stuff like the weird Void afterlife thing, Fixer's situation, how Idealist wasn't seen as being truly alive until she got that life energy spark, etc.)
Though granted this still raises about as many questions as it answers.
Visionary w is slowly dying and by tactics is essentially a walking corpse before her death. La capitan who should have died when she fell through that time vortex.
Miss information who should have been killed in an accident but fell through universes.
Yeah, quite a few "do their bodies count as alive" characters
Dark Watch Fixer
Fanatic
Apostate
Absolute Zero
Writhe
Medico
Omnitron
Gloomweaver in both forms
Spite… yeah drugged monstrosity and undead spite
Akash of many names
Anubis
The Vampires
Biomancer and his children
Zhu Long
Wager Master
Oblivaeon and the scions and aeon men (Borr, Nixious, Darkmind, Voidsoul, Aeon Master, Sanction, Empyreon, Progeny, Faultless)
Balarian
Spoiler AeonGirl
Mangrove
And then with the "defintely alive but confusing" section I'd put
Nightmist
Scholar
Guise
Haka
Idealist
Idolater
Kaagra and the Bloodsworn
Jansa and Endlings
And I probably forgot a few obvious places on the list
