Vectorgreg is the first editor on Plants vs. Zombies Wiki. Although he did not officially found the Wikia, he created the original articles about the plants and zombies, as well as being the first user to adopt the Wikia after Wckd went inactive. Unfortunately, as of August 2016, his account was hacked and has been blocked globally from all of Wikia.
Drek'TharSuperSword is an bureaucrat on this wiki. He's known for hating zombies who wear one shoe and really likes the GW2 chemist zombie's appearance as well as zombies who wear a pair of shoes. Sometimes his friends call him a nerd because he just talks about computers and technology too much, and he doesn't like being called that. He likes doing back-end things that aren't easily spotted like MediaWiki editing, page management, etc.
LettuceBirb is a bureaucrat on this wiki. He specializes in uploading images, particularly icons. She also handles most of the Chinese exclusive games, most noticeably finding the long forgotten Social Edition plants. They also draw a lot and runs a PvZ related askblog (currently on hiatus tho).
TheZombiemelon is an administrator on the Plants vs. Zombies Wiki. He enjoys PvZ2C, CSS, fixing grammar on articles, cats, and the outdoors. Other games TZM enjoys are War Thunder, Borderlands 2, and Rocket League. He is also currently working on a secret project.
CWJ-D is a moderator on this wiki. He focuses on formatting, grammar, and strategies, and he freaks out when he sees sloppy editing. Has a few alternate universes in his mind, one being a Plants vs. Zombies Heroes AU known as Fanatic Fandom, where he (Eccentro) is the mastermind who created everything. Also owns an evil clone that (harmlessly) harasses users and works as a Bot on this wiki.
GamesterD is a moderator on the wiki and admin on discord who likes...games. Mostly PvZ, Smash, and Fire Emblem. Though he's mostly a forum guy and works more on discord, he will actively patrol the wiki's recent activity to see any screw ups and undo them (Probably).
Shark is a rollback on this wiki. Sharksurcool is no dunce in the field of ecology. He knows many facts about things that other people may not know. Mainly sharks, but also others. But there is one thing that everyone knows about that he doesn't know about: dogs.
Tile Denial is a rollback on this wiki, who has been playing Plants vs. Zombies 2 for a long time, but stopped eventually because of laziness and only checks back on updates. (S)he also likes creating inconsistent PvZ fanfics focusing on an underrated inventor and the lengths he goes just to get people's attention without getting an explosion in his face.
CWJ-D's evil clone is a very evil bot - at least, that's what he's supposed to be. Since CWJ-D doesn't interact with scumbags anymore, his evil clone has nothing to do but simply show up to work. (And even then, he always runs off somewhere else soon after that.)
Elemec is a veteran user from the Wikia and Discord themselves. Being on the Wikia since 2014 and on Discord since early 2017, he's shown to be pretty active, optimistic and enthusiastic towards the community. Has already set his heart for a special someone, who he really appreciates as not just his romantic partner, but as a whole.
Tito is a loser who "administrates" the server. He's been on the Wikia since 2015 and even without an account since 2013, and he will actually destroy you in a Fortnite 1v1. If you ever steal his V-Bucks™️, your life won't continue for much longer. He has HAD a streak of playing every Plants vs. Zombies 2: It's About Time™️ daily pinata for over three years now. He contributes to most active conversations in this server. Most of the time.
