Reaper

Description
The Reaper is one of the event zombies in the Halloween Event 2019. It first appears on wave 12. It can also be summoned by Jack O' Bot.

The Reaper can be a threat as it can spawn in groups and summon lots of zombies while also being protected by other zombies making it easier for Reaper to summon more zombies and you ending up dealing with even more zombies.

Appearance
The Reaper represents the grim keeper. He wields a scythe, wears a black robe with a black hoodie, chains and white gloves.

This zombie acts the same as Necromancer and Dark Necromancer.

Strategy
Sometimes it's hard to deal with Reapers because groups of them summon many zombies keeping the Reaper protected. Towers like Turret and Outlaw can easily take care of Reaper if both set to "Strong".

As for now the Reaper only appears in the Halloween Event 2019.
