You can tell a lot about a character from what sort of people like them... I think. Sometimes the wrong people like certain characters, but it's not like their enjoyment of these characters comes from nothing. If a bunch of weird libertarians like The Punisher, then I can assume a sizeable portion of his comics agrees with their worldview. So, what am I supposed to feel knowing that Alan Moore is apparently a big fan of Herbie Popnecker (https://alanmooreworld.blogspot.com/2019/11/moore-on-jerusalem-eternalism-anarchy.html)?
So, you might look at this character along with his comic being named "Fat Fury" and understandably come to the conclusion that this character is a slightly mean-spirited joke. Indeed, he's quite the opposite of a superhero: short, out of shape, not particularly emotional, and his father absolutely hates him... but he's also basically a God. Satan cowers before him, World Leaders go to him for advice, and women find him absolutely irresistible!
Most of his powers came from magic lollipops procured from the Unknown, which enabled him to talk to animals, shoot beams of fire from his eyes, and whatever else the plot needed. They even help him Time Travel at one point, though there he also felt the need to sit down inside a Grandfather Clock.
I think that's why the character doesn't end up feeling too mean-spirited to me. He's fat, but it never bothers Herbie. To put it in his words, "So I'm fat. So what?". It's joked about, sure, but we also get jokes about how unphased he is by the goings on around him, or his dad getting furious at seeing his son winning, or various other gags that don't fit into these categories.
If you couldn't tell by Alan Moore being a fan, Herbie's had quite the legacy. He appeared in 29 comics (23 of which are his own self-titled series), has made many appearances in webcomics due to his accidental Public Domain-ness, and even has his own fansite (which I recommend checking out btw, it covers many topics I didn't have the time to go into https://herbiepopnecker.com/). Good on you, Herbie!
