Bionic Bash is an ability for the Z-Mech in Plants vs. Zombies: Battle for Neighborville. When activated, the Z-Mech will punch the ground, dealing 75 damage and knocking enemies back, similarly to the Mech's Robo Stomp in Plants vs. Zombies: Garden Warfare 2.
Punches the ground, damaging and knocking back enemies back.
Bionic Bash is near identical to its predecessor, and can be used in the exact same way. Use it to vanquish nearby plants, and to break apart crowds of plants swarming an objective. If your primary weapon overheats or Missile Madness is on cool down, it serves as a great way to finish off enemies.
