X-Men Red (2018) #4: "The Hate Machine, Part 4 - Small Problem"

Since the earlier review of a Vision and Scarlet Witch issue turned out to be quite brief, I thought I would knock another one off with this X-Men Red offering.

Namor appeared in the first issue of the series but did not show up again until this one, and barely so. But the first panel below at least explains his purpose in this book. 

They mean that literally. Certain people are being infected with some nanotech that causes them to be susceptible to mind control directed towards killing mutants. The clothes to which the ladies (the Laura Kinney Wolverine on the left and someone annoying named Gabby who goes by Honey Badger on the right) refer include a dampener that negates the tech's effects.

The X-(Wo)Man named Storm had been earlier affected by it and attacked the always lovely Jean Grey. They certainly don't want Namor turning on them.

So again, that's the extent of Namor's inclusion. His appearances in this book, at least first few issues, tend to be quite brief but they do have some significance. 

Vision And The Scarlet Witch (1985) #7: "Batteries Not Included"

 This is obviously inspired by the release of the Wanda Vision TV Show...

Namor appeared in the previous issue of this mini-series but contributed little more than comic relief. Based on the preview for this issue, it seemed like he played a larger role in this one, but unfortunately that's not the case.

He and Captain America are in the training room at Avengers Mansion when Vision phases through the ceiling and startles them. The distraction causes Namor to get tossed around by their robotic opponents.

That's right, Captain America gets corked by that machine behind him because he's preoccupied by Tony Stark's bottom line. Too bad he let himself be distracted! You can't do that when you're in combat! Jackass...

Vision is there to ask the two of them about the original Human Torch, whose body he inhabits. He is, once again, having an existential crisis of some sort. As a result, we are treated to some brief Invaders flashbacks. 

The information is of little use the Vision, as it turns out, so he takes his search to Project Pegasus. It's a solo thing though, so the former Invaders are not seen beyond these first couple of pages of the book.

I guess that's that. I'd hoped for a full-length guest-appearance but Namor's role was wrapped up by page 5. Bummer.
