Nerflower

The Nerflower is an instant-use plant in Plants vs. Zombies: The Final Showdown which "nerfs" every zombie onscreen, substantially debuffing powerful zombies but having little or no effect on weaker ones.

This effect causes any zombie with more than 1800 DPS (90 peas) to instantly have their health set to 1800, enabling instant-kills to OHKO them.

Additionally, it reduces the speed of any zombie that moves faster than a rate of one space every four seconds, causing them to move at that speed.

Lastly, it disables certain abilities across the board. Jumping zombies can no longer jump, zombies which summon others in any way (Wizards creating Zombie Sheep, Dancers producing Backup, Gargs throwing Imps) cannot use their summoning effect, and all zombies that have some form of healing effect lose that healing (whether it affects the user or ally zombies).

Despite this effect being very powerful, she is a very costly plant that can't directly defeat any zombies, and has an extraordinarily long recharge timer. In addition, she doesn't affect Micro Bosses.

It is unlocked after beating Night 11 of The Great Graveyard.

Origin
Her name is a portmanteau of "nerf", meaning to weaken something when rebalancing a game, and "flower", the type of plant she is based on.

Appearance
Similar in appearance to a Sunflower, but with a grey face and black petals, and a sort of glitched, blocky appearance.

Almanac Entry
Nerflower

Nerfs every zombie onscreen, reducing health and speed, and sometimes taking away other abilities.

Range: whole screen

Usage: single-use, instant

Special: reduces the health of any zombie that can survive massive damage, reduces the speed of any zombie faster than average, prevents zombie spawning and healing abilities

When asked how Nerflower does what she does, she simply responded mysteriously, "I can hack into the fabric of this fake world, and modify what I want at will." No one is quite sure what that means.

Cost: 300

Recharge: ultra slow

Strategies
Nerflower is ideally used during huge waves. When combined with a Doom-shroom, you can legitimately defeat any huge wave for 425 sun (500 during the day), no matter what, due to Nerflower allowing Doom-shroom to one-shot zombies such as Gargantuars, Weightlifters, or even Undying Zombies.

Despite its recharge timer, with most strategies you should have plenty of time for Nerflower to recharge in between flags, unless using extremely high DPS strategies (such as Fire Pea Pod or Fire Anger Pea strategies) which would likely defeat the strong zombies that this debuffs anyway.

When combined with Fastflowers and Imitater, you can potentially use this approximately once every 34 seconds. Combining this with sufficient stalling tactics could theoretically allow you to nerf every single zombie, but would require serious effort to set up, most likely only being viable in endless modes.
