In Tempest’s bio it mentions that a few other Maerynians survived the crash landing on Earth. I imagine that they also have the power to control lighting/weather like Tempest, so where are they? It would be kind of cool if there were (in the Sentinels Comics Universe) a strike team of Maerynians who work together for heroic or nefarious aims. Would they all be good guys fighting for their adopted planet or would they in a Magneto-esque twist want to enslave the Earth as Voss and the Thorathians enslaved their people?
There were only a few of them, and they were wounded, so I don’t think it’s unlikely that they died when captured by F.I.L.T.E.R. Even so, the Maerynians being a peaceful people as they are, they would most likely look down on Tempest’s choice to become a combatant. So if they are still around, it’s likely they’re in hiding, and we may not see them for a long, long time.
