Undead, yes. I consider her status to be unknown. The Prime writers essentially wrote her out of existence.
She's considered undead. And also might be actually dead now, depending on whether or not she was rescued before she ran out of energy.
I feel like she is "alive" to an extent. Maybe she'll show up in RiD, and the Prime Autobots all team up again?
That's almost certainly just a generic that uses her model, not Airachnid herself actually being in the show; remember that last we saw, she was basically stuck on one of Cybertron's moons and slowly killing her Insecticon swarm for their Energon. Once that supply is gone, Airachnid is SOL. And given how nobody's ever even mentioned her in RiD, I think she's probably dead. And good riddance! I would have been entirely disinterested if they brought Airachnid back at all.
she (and her insecticon army) probably in stasis on one of the moon of cybertron... it's a horror movie waiting to happen..
This orange "Airachnid" is an unnamed generic reusing her character model. Note how it has no spider legs or propeller on its back. It's from the NuRID "Metal Meltdown" episode. All generics on Glowstrike and Scorponok hip were reused old models - they also reused Vehicons and Underbite models in different colors.
Man, i kinda wished Hasbro or Takara made those as actual toys. I mean,it be neat if they made redecos of prime toys as exclusives or something? I mean i wished generics that share body types with existing characters with toys could be used as a redeco choice (I mean all those Armada Generics that share with all those combiner components for example, they could totally be done. I just wanna see the back story of those guys. Even if it's a bio) Wait we talking about Airachnid? Well she's dead. In more ways than one. Spoiler (She's dead to ussss... Also she's a Zombie,i'm not sure she will come back in a sequel to RID though as a focus... just to end her. For good.)
