Adventures of Rex the Wonder Dog #4 (1952)
by John Broome & Carmine Infantino
When it comes to animal superheroes, DC Comics is the undisputed champion. Already in the 50s, they didn’t just have Rex the Wonder Dog fighting Nazis…
![]()
…but also a chimp, whose story is being told by Sheriff Florida here.
![]()
Already from the start, Bobo is smarter than your average ape.
![]()
The story kicks off when the sheriff is called to investigate a murder, and Bob was the only witness.
![]()
If you’re finding it strange that the chimpanzee is not able to talk with full sentences… you might have read a bit too many Silver Age stories.
![]()
Sir, this is the DC Universe. Never understimate how smart an ape can be.
![]()
Case in point: not only he nearly solved the case, but he can think like a human unlike regular chimps.*

![]()
He escapes from his cage during the night.
![]()
The assassin tries to shoot him, but Bobo retreats into the jungle section of the zoo.
![]()
Where he is basically unbeatable.
![]()
This scares off the killer to the point of blaming Bobo for the death of his master…
![]()
…but Bobo has friends in high cages.
![]()
The killer is arrested, and Bobo is awarded a lifetime supply of bananas.
![]()
At the time of this review Detective Chim is still around 73 years later.
That’s a lot of bananas.
Historical significance:
/ 10
Modern stories basically ignore this story, even if Detective Chimp had a resurgence of popularity.
Silver Age-ness:
/ 10
The chimp thinks in full sentences, but that’s about it.
Does it stand the test of time?
/ 10
Well outside my genre, but it’s a cute little self-contained story.
He’s not even called Detective Chimp in the story, it’s just the story title.
It sure looks like this was intended to be a one-off story.
How close is this to the modern character?
/ ![]()
He doesn’t have the cap, doesn’t smoke, doesn’t talk, and isn’t really a full detective yet.
You’d think the premise wouldn’t be enough for many stories, but Detective Chimp skips only a few of the 46 issues of the series!
He gets his trademark deerstalker cap in his second story. That’s obviously a nod to Sherlock Holmes, despite the fact that he never wears it in any of the Arthur Conan Doyle stories (that’s a detail from later illustrations and adaptations).
![]()
Compared to Rex, Bobo’s adventures are less action-oriented and relatively more grounded.
He still CLEARLY has human intelligence, even if he barely manages to communicate.
![]()
Especially to the banks.
![]()
He might also be the first chimp to ever have a bank account.
Although this is set in Florida, so who knows.
![]()
Things don’t get too ridiculous until issue 29, where he’s able to disguise himself as a human.
![]()
This is a story about a chimp on stilts who wears a suit and a fake beard in order to visit a science exhibit.
In other words, one of the greatest achievements of the human race.
![]()
After Rex’s series ended in 1959, Detective Chimp faded into obscurity until 1981, when DC Comics Presents #35 showed what happened to Rex.
It’s the first time the two characters meet, they never did in the original series.
![]()
That’s the story where both animals drank from the Fountain of Youth.
![]()
He even manages to make a really, REALLY tiny cameo in Crisis On Infinite Earths #11 in 1986.
![]()
Given that EVERYBODY (except Hal Jordan) appeared in Crisis, Detective Chimp seemed to be destined to never show up again.
But already in 1989, Secret Origins vol2 #40 decided all was needed was to update his origin… to make it MORE Silver Age than the original!
Because now we learn that Bobo was a regular chimpanzee until he accidentally swallowed a microscopic alien ship.
![]()
I’m pretty sure you have to be on drugs to understand this one.
![]()
Detective Chimp returned, of all places, in Green Lantern vol3 #30.
A bit ironic when you consider that Green Lantern vol1 #30 was the first appearance of Streak The Wonder Dog, who eventually replaced the original Green Lantern.
The reason for Bobo’s return is a Gorilla Grodd story, so Green Lantern has to work with the Bureau of Amplified Animals.
![]()
Where Detective Chimp is the head of investigations, and he now has telepathic powers.
Just like with Rex, we will learn that it’s because of the Fountain Of Youth.
![]()
The story also firmly establishes Bobo’s friendship with Rex.
![]()
Detective Chimp continued making sporadic appearances in the corners of the DC Universe, until the 2005 event “Day of Vengeance” gave him a prominent role.
By this point he’s shown to be able to talk normally, he’s a chain smoker and has a drinking problem.
![]()
Which lead him to join Shadowpact the following year, becoming a prominent member of the team for its 25 issue run.
![]()
As a follow-up, in 2007 he came THIS close to become the next Doctor Fate.
![]()
But he renounces the title when the responsibility proves too much for him.
![]()
Still, it had its perks.
![]()
He’s proven to be as much as a detective as Batman, even helping him in a case against Riddler… who didn’t even notice he was talking online to a chimp.
![]()
The sci-fi origin introduced in 1989 seems to have been completely replaced by just having the Fountain of Youth making Bobo both immortal and sapient, at recently as Dark Knights Rising: The Wild Hunt in 2018.
![]()
He even got to join the Justice League!!!
Well, one of the spin-off teams (Justice League Dark), but still.
![]()
Very impressive turnaround for a write-up you said yesterday you hadn’t intended to write!
Wasn’t too hard… Chimp’s first story is very short and I already flipped through his original run while researching the Rex review. Plus he shares a lot of history with Rex, and since he’s a more popular character the are better resources to track his story.
All the same, this is a nice retrospective. Thanks for writing it.
Things don’t get more Silver Age than a zoo including quicksand as part of its jungle exhibit.
