Besides her decently high health and DPS, the scariest thing about Winged Pigge is that she has a 100% chance to weaken cats to 10%, making her much harder to defeat if she gets to the player's heavy hitters. She has only 10 more range than St. Pigge but can hit units up to 340px away from her, letting her weaken groups of mid-ranged cats while also tanking hits for other enemies.
Do not let her weaken your attackers as that will make her extremely difficult to get rid of.
Cyborg Cat outranges her, deals heavy damage when stacked, and is immune to her weaken ability, which allows her to fight on even after Winged Pigge attacks her. Beware her high cost though as if you don't stall beforehand, you could end up without money to continue spamming her.
Many Uber Rares from the Ultra Souls set are excellent counters to this enemy: King Gamereon for his resistance to Angels and immunity to Weaken, being able to nearly solo her at level 40; The Peach Devils for being able to freeze her, and if Talented, weaken her too; Jizo's Moving/Mega-Castle for its huge damage, being able to kill her in a few hits although if you are using his True Form, be mindful of other attackers that may do enough damage to cause Winged Pigge to be knocked back by the first two multi-hit attacks; and Kinrangers Robo/GigaForce for being able to slow her, and if True Formed, Curse her too.
Kalisa will be weakened and knocked back before she can hit Winged Pigge, so her first strike is the most valuable against her. Otherwise, it is recommended to use Lesser Demon Cat, as he deals extreme damage and is immune to weaken; and can effectively do what Kalisa should do. Even then, Winged Pigge attacks fast enough to nearly perma-kb Lesser Demon, so don't hesitate to invest in support, and his Talents.
Curling Cat is a useful tank against Winged Pigge; and should be unlocked at this point in the game. If not already, hypermax this cat without regret.
Kasli the Bane is excellent against Winged Pigge thanks to her ability to disable her weaken from a safe standing range.
