Captain America and Air Wave

 

I actually experienced a few Brooklyn blackouts during my 20 years living in NYC.  I remember one time my friend in the building came to my place and we cooked everything in the fridge on the gas stove and played scrabble by candlelight while listening to battery operated radio.  We definitely made the best of it, it was a fun night actually!

Firestorm and Beta Ray Bill

 

I've been waiting for Beta Ray Bill to show up in the MCU for a decade, but other than an Easter egg statue, he has yet to be seen.  With the underperformance of Thor: Love and Thunder and Chris Hemsworth's desire to slow down his acting career, who knows when or if we will get another installment?  Hopefully even if Thor himself is out of the picture for a while, BRB can still find a place to appear in the MCU.

Hyperion and The Atom Vs. Brainiac

 

There have been reports of Marvel looking for a leading man type to play the antagonist in the upcoming Thunderbolts movie, an extremely powerful character that they are reportedly considering Ryan Gosling (or someone like him) to portray.  Some have speculated that this is Hyperion, while others think it will be The Sentry.  I think The Sentry is more likely as well.  I'd love to see Hyperion join the MCU - but he would ideally have the rest of the Squadron Supreme with him so that a full on slugfest with The Avengers can go down.
