Happily skipping along, gun in hand and brain tucked under arm...That's how I like to think of Monsieur Mallah!
Seriously, you have Gorilla Grodd, Monsieur Mallah, Detective Chimp, Bat-Ape (no, not Nightwing), and Beppo, and a host of ape versions of Marvel’s heroes residing in The Marvel Ape Universe.
Furthermore, it seems that shapeshifters like Changeling are most popular when they morph into chimps, gorillas, monkeys, etc. Hey JJ (J'onn to those not hip to my new starting a trend initiative), want to be more popular than Supes and Bats put together? Just morph into a chimp or a gorilla every few issues.
And it’s not limited to comics, either. In television, there’s Mojo Jojo from The Powerpuff Girls and the gorilla-themed Optimus Primal from Transformers Beast Wars and Transformers Beast Machines television series from the 1990s.
Of course, the vast majority of the DC primates are products of early Silver Age insanity, but that leads me to my next question (marked Question 2 for your convenience :).
Question 2: Why are the super-powered apes still popular with readers and some writers?
I couldn't resist this rather apt image...
Perhaps I should scrap my work in progress and write an ape script instead...
