Why do these CINO’s have their arms outstretched? Are they doing some holy wave?
It’s the Jack Kirby posture. ZAAARK!!! Bless rays shoot from their extended arms, spoiling the evil intentions of Galactus! Yay, the Earth is saved once again by these brave super heroes!!

They are supposedly extending their hands in prayer (assisting whoever might be pronouncing the prayer). It was done frequently in the Charismatic Renewal. They are "helping," so to speak. I don't know how appropriate or licit it might be. Some speakers (priests or otherwise) invite the congregation to add their prayers in this manner.
