Since both zombies and vampires are equally popular, why not combine the two? A Vampire Zombie would be devastating. It would attack only the first plant it encounters, and then die. It would bite only once, and the plant it bites would turn into a Dark Plant that would instead fight against you. A Dark Wall-nut will block projectiles (except lobbed shots), and Dark Snow Peas will attack the plant behind it and slow down its rate of fire. All Dark Plants will disappear after about 20 seconds after being bitten. On contact instant kills would still kill a Vampire Zombie. The Vampire Zombie's only two weaknesses are Garlic and Hypno-shrooms. Garlic would act as an instant kill for Vampire Zombies after one bite. A Vampire Zombie will eat the Hypno-shroom and then bite/hypnotize the first zombie it encounters, including Gargantuars.
