Fun fact #1: I actually wrote this storyline - or some version of it, anyway - years ago. In the intervening time period, Max has been reimagined by others as an anonymous vigilante not once, but twice, once for the cause of animal rights as the Animal Avenger (in the radio play Sleuth!), and once for the cause of sexual gratification as Cherry Popper (that was a commission I did, it's in the gallery, obviously NSFW). Neither is especially canonical, of course, but both are pretty much in character.
Fun fact #2: Did you know Aquaman had a truck for a while? It's true. He had a truck full of water that he drove around in, and there were swordfish and anglerfish and such in there, and he used them as swords and flashlights, respectively, despite the fact that they would be worse at those jobs, objectively, than actual swords and flashlights.
I'm sorry, but Aquaman is the King of the Sea. He has unquestioned inherent dominion over three quarters of the Earth's surface. He commands - not "talks to", you don't have a conversation with a brine shrimp - he COMMANDS MOST of the animal life on the planet. He has an entire underwater kingdom full of subjects for which he is responsible. If something falls from space and lands in a random spot, odds are good it's his problem. If something burrows up from the core and emerges in a random spot, odds are good it's his problem. If a human ship hauling anything weird has any sort of problem in open water, it's his problem.
If you feel the need to give that character a fucking truck so that he can drive around downtown Chicago and thwart bank robbers and purse snatchers, you are a bad storyteller, and, I dare say, a bad person. Aquaman isn't boring. You're boring.
Fun fact #3: Whenever someone is brought low by their own hubris, the phrase my friends and I typically use is that they've "got a case of the hubes". It's fun to say.
