Teenybopper

Teenybopper
This mutation extends the player's bat-wielding arm with a small writhing imp, passively increasing the range and width of the player's bat attacks. The melee buff is extremely useful for extending the reach of the Sword of Rejection. Its primary ability activates a "Rage" mode, dealing sustained bursts of damage to whatever enemy the player can hit, as long as it isn't interrupted. It is useful for attacking high-health enemies quickly, such as Bosses or Alphas.

Blast
Teenybopper can be upgraded to Teenybopper Blast, which adds an Area of Effect damage to surrounding enemies when Rage is activated.

Frenzy
Teenybopper can also be upgraded to Teenybopper Frenzy, which increases the duration of Rage attacks and decreases the recharge between Rage attacks.
