Hmm? What? Urkel used the WildC.A.T.S’ blender again (let’s all be thankful Waldo didn’t get his hands on the Creation Equation again)?
Zealot is definitely going to roar when she finds the used blender in the morning…
Nothing but the chirps of crickets can be heard for the next few seconds.
Anyway, thanks for the heads-up, @HubCityQuestion. 
Cracks his knuckles over his keyboard, then hits Play on the WildC.A.T.S theme song and begins hitting the keys, ala Jessica Fletcher in the opening of TV’s Murder, She Wrote.
I’m glad you’re enjoying Zealot in the new BOP, @Chain_Twix! 
Her first appearance is in #1 of the following series:
She’s headlined her own mini:
Grifter is a frequent love interest of Zealot’s (especially in the pre-DC years of WildStorm), so check out his first series for some Zannah action (emphasis on #8):
Grifter v2 (emphasis on issues 7 and onward):
When Zealot got wild to the core:
For those who came in late: The above titles were originally published when WildStorm was part of Image Comics in the '90s and before DC acquired the WildStorm imprint in 1999. That is why relatively recent and current DC logos adorn the digital editions of pre-'99 WS books.
Consequently, you may see mention of or guest-stars from Image in the pages above, as WildStorm was part of the overall Image Universe when those particular comics were originally released in print.
This one isn’t available in digital yet, but it should be an easy back issue bin, used bookstore or eBay find:

If you’d like to see Zealot in animation, look no further than the below YouTube playlist, which features the entire WildC.A.T.S TV series (its 100% legal and official, as Nelvana owns the show and is affiliated with the Retro Rerun channel):
There are also Zealot action figures. More deets to follow if you want (this post is already long-enough 
).
There are other titles featuring Zealot in various capacities. The above highlights are a good starting point however, so I hope they will scratch your initial itches for more Zealot, @Chain_Twix and @RG02.
