They watch the others go into a full attack, from the center tower to the outer defenses there was explosions galore.
But that doesn't mean the Powerpuff Girls call off their own assault, instead they took advantage of them and started on the top floors of the four non-collapsing towers.

Buttercup took north, she burst through a large pane glass window while two guards were readying their weapons and cleaved the one on the right then the one on the left in one swipe.
She flown down the hall breaking down doors and once in a while slicing a monster, a guard or a machine to pieces.
She came back to the point where she came in, figuring since she isn't going to be here again she shrugged and charged her special attack system.
The blade of the naginata glowed softly and then she raised the blade up and slammed it down.
The energy released pierced through the entire area, destroying about five feet all around the attack area and it went about two floor below and one floor above.
She charged another attack and destroyed a good chunk of the floor she was on, going through the hole in the ceiling and processed to reck terror on the poor souls on that floor.

While Buttercup was vaporizing the top of the north tower her girlfriend, Princess, was blazing through the creatures with her rapier in the east tower.
While her destructive waves weren't as bad as Buttercup's but they were just as painful, she created a large arc of fire with her sword.

While both were having fun Blossom was going straight for the west tower's core, which wasn't much.
This is too easy she thought as she fired round after round into the guards and monsters.

She charged her shots and below what appeared to be a computer center.

All three met in the south tower, leaving the other towers so close to collapsing then a mere breeze might destroy them.
A explosion rocked the base of the east tower, the girls watched as multiple explosions tore it apart and send it crashing into the west tower.
It seemed the computer core that Blossom destroyed in the west tower controlled the chemical flow in the labs in the east tower, if that computer were to shut down then a lot of nasty chemicals would mix and they would wind up with what they have right now.
A large bond fire.

"Well" Blossom said tearing her gaze away from the large inferno below, "it's time for the last one."

Angelique lead her team into the back of a unprepared guard troop, she stood on one foot and stun quickly while sending energy out, creating a large tornado that sucked up most of them and tore them to shreds with bouts of solid power within the twister.

Her soldiers sally forth and attacked with such a gusto that it terrified the enemy.
And while she was leading them into the center of chaos, Jack and Mitch was making sure that the large creatures that were coming out of the underground labs.
They fought and beaten every last creature on the ground.
Now it was time to enter the last tower standing.

----------------------------2

The west was the main computer center, controlling the info from the work offices of the northern tower and keeping millions of dangerous chemicals from clashing into each other in the east tower.
While they supported each other the southern tower was independent of the others, this tower house the worse of the worse.
Within large tubes and steel walls the crime syndicate's more powerful monsters and creatures.

Powerpuff Girls and the Gezoisya Zubatsu were going into this tower.
They were going to face the biggest challenge of they're lives.

When the CCPD destroyed the center tower Usagiko and Lichung were still in Dr. Zeighger labs, with all of the towers being destroyed they had to make a hesitate retreat through the train tunnel.

Unaware of what awaited the on the other side of the tunnel.
Which was Michelle holding a desert eagle and Dr. Zeighger might having a use for them.
