Undersea Agent #5 (1966)I'll mainly comment on the first story, as that's the one by Gardner, but I can't resist throwing in something about a few of the ads too.
Cover - The mechanical/robotic monster immediately caught my eye. It made me want to open the book to see what this creature was and what it did.
Born is a WarriorSo they really called the hero Davy Jones? And yes, he did have a locker (p. 2). Of course, the Monkees TV show featuring real-life pop star Davy Jones made its debut in September 1966. By the time this comic book came out, pre-teen and teenage girls would be more interested in the pop star. Who can forget the Brady Bunch episode when Davy Jones goes to the prom with Marcia?
And while still on the subject of names, Panther mentioned the sidekick’s name ‘Skooby Doolittle’. Did he inspire the canine Scooby Doo? Scooby Doo didn’t debut until 1969, so who knows?
Anyway, back to this story.
I liked the story overall. Davy is a good mentor--skilled, humble and encouraging to his protege Skooby. I liked the way that Skooby was the one who ended up digging deep and saving the day, rather than just letting the hero save everyone. A self-sacrifice theme befitting the best superheroes.
Some good art in terms of action and perspective. A taste of the Batman TV series with all of those Pows and Sockos. I liked the way the mechanical monster was drawn, though he looked a bit too benign in some frames.
Couldn't help finding a typo at the top of p. 10 when Mike fires a charge. Mike?? I assume that's Davy. And speaking of typos, I had a quick flick through the other stories and the hero's name is sometimes spelt as Davey.
Anyway, a good story overall. I haven't come across this comic book title before, so I would have missed some of the background to the character in previous editions.
Selected AdsI love old comic book ads. You can usually find some gems.
Chet Atkins - If only my parents had known I could learn to play guitar like Chet Atkins for just $2.98 US, they wouldn't have had to fork out money for me to have guitar lessons from 1969 to 1973. Sshhh ... don't tell my Mum!
Refrigeration and Heating - Build a complete refrigeration system at home? It reminded me of the 'Young Sheldon' episode where boy Sheldon takes the family refrigerator apart and tries to fix it from a book. What could go wrong?
https://www.youtube.com/shorts/790UBQA0wLMFun Supermarket - In the middle of the Cold War, who wouldn't want a mushroom cloud-shaped ring of smoke coming out of an ashtray? And if that wasn't to your taste, you could always stick a snowstorm tablet on the end of your Dad's cigarette and watch tiny snow fill the room; or electrocute your friends with the miniature electric chair effect. Hours of fun for the whole family.
Sell Grit - Ah, the good ol' days when an honest lad could sell newspapers and have prizes like hunting knives and tomahawks coming through the mail.
U.S. Government Surplus - Better still, send away for the U.S. Government Surplus catalogue and buy yourself that machette, hand grenade or cannon you've always wanted

Cheers
