PVZ COMICS/GAMES THEORY: ZOMBIES AMONG THE HUMANS
(Before starting, if i got anything wrong, im sorry! this is my first theory)
I'll be basing this theory largely on the comic called Bully for You. Other material will be included.
To start: I want to and will base myself on the headcanon/opinion that Zomboss is the same age as Dave (36) or that he is a little older.
In this image, you can see the zombie school. On the side, there are three signs. One of them points the way to a school FOR humans.
In my opinion, it's quite curious that zombies already had a school, a separate education.
They could be considered a separate species, with special schools for them.
At least in my country (Argentina), the minimum age to enter university is 18.
If we assume Zomboss is 36, 18 years ago, humans lived (apparently) in peace with zombies.
Interactions with zombies at that time are more casual, with people selling them things, etc.
And if we think about it this way, the zombies' current interactions with humans aren't so unusual.
It's known that humans in Neighborville act stupidly, as if they don't care or don't know about the danger they face.
But if we consider that they were used (at least before) to living with zombies, it's understandable.
Below are some examples/panels that can help explain this:
Now, let's talk about Timepocalypse and what happens in it.
Zomboss sends the zombies to retrieve parts from a machine.
Since it's based on PVZ2, the zombies are in ancient Egypt.
This causes a change in the timeline.
Remember, Bully for You canonically takes place AFTER the events of Timepocalypse (weeks or days later).
The timeline was altered because the zombies being in Ancient Egypt and staying THERE (there are no signs that they were all removed from there) would cause the zombies to begin living among humans from that moment on.
After the fight with the zombies, Patrice becomes the queen of Egypt (which also implies quite a few other things), and we're shown a zombie and a human as her servants.
The plants don't attack them.
Right after that, Patrice leaves, leaving the zombies there with the humans.
It's even possible that a zombie ended up in power, but that's up to you.
I almost missed it; zombies have existed since the time of the dinosaurs (following this same logic as before).
FROM THIS POINT ON, I'M GOING TO START MENTIONING THINGS THAT I BELIEVE, WITH ARGUMENTS.
Also, there's a chance that the Plants vs. Zombies: Garden Warfare comics and games are part of the same timeline/universe.
Since there are three comics for Plants vs. Zombies: Garden Warfare 1, 2, and BFN, there's a timeline (for example: Comics 2 and 3 are connected by the Thumb War event between Nate and a Gargantuar).
That's why the Gnomes are also important in this situation.
The timeline has already been altered several times (Plants vs. Zombies: Garden Warfare 2 comic, Timepocalypse), generating changes in history and, probably, in people's events and memories.
Humans have normalized zombies so much, but that's because they've been around since the time of the dinosaurs. In my opinion, after Zomboss graduated, he assembled his army of ALMOST every zombie he could (also mass-creating many more), causing them to distance themselves until the events of Lawnmaggedon happened.
That's why humans don't recognize zombies, because they haven't seen them in almost 18 years.
I think this is all I can refute for now. If you have anything to contribute or say, feel free to say it.
SOMETHING THAT HAS NOT MUCH TO DO WITH THIS, BUT IS INTERESTING:
The artist of the first three comics (Lawnmaggedon, Timepocalypse, Bully for You, Lawn of Doom, etc.)
believes that Zomboss was always a zombie (if you search his account you can find the post.)
