This enemy, while not so durable, has extremely powerful Long Distance Area Attacks, strong enough to destroy most units in one hit. Fortunately, Hackey has an extremely large blind spot of 1200, with his standing range being well within it, meaning most units can sneak inside due to his long attack delay.
Time your attackers perfectly to minimize Hackey's destruction, as anything he hits will lose a massive amount of health or outright perish immediately. Much of the same strategies that work against the original Tackey should also work against this enemy, but you do not want it getting a hit off on any of your important units. Luring can work, but be careful not to let him get too close to the Cat Base, because even a maxed base can only withstand three fastballs from this fiery pitcher.
A pitcher whose fighting spirit is as hot as his blood. Warms the bench for his teammates with his body heat. A tough opponent who ignites the ball and calls it a "demon ball" before throwing it from uber-long distance.
