Evolve or die! 30

[More of me, Scruff, the Girl in Grey's cool teenaged sister, fighting crime with the uber-cool Black Kitten and the Outsider, who's also very cool]
"Toxic's here!" I hissed. Emily drew her crossbow and Laura dipped a hand into one of the equipment pouches in her belt. I decided not to ask what she was going to use - it couldn't be much more deadly than Emily, after all. Hey, Emily was trained to kill people!
"We've got to get to the hub before they do!" I warned. Laura nodded.
"Okay. Emily, cover us. Come on!"
I kept my black cape (boy, I'm glad I didn't pick a 1940s Robin costume. Cold legs AND a yellow cape!) drawn over my colourful costume. Laura was just invisible in her black outfit. Our night-vision lenses meant we didn't have any trouble seeing, despite the fact that the lights were out.
And boy what we saw! Toxic was a woman in a skin-tight green spandex costume. I heard Laura chuckle next to me.
"Is spandex really that functional?" she asked.
"Says girl in show-off black outfit," I joked back. I noticed that Toxic had some sort of gun stuck in the top of her right boot, and devices I didn't like the look of at all on the backs of her gloves. But then she was a super-villain.
"I'll go first," Laura whispered to me. "I don't have any exposed skin in this costume, so if she tries some sort of contact poison, I'll be okay."
"And if she tries to dissolve your costume with acid?"
"She's got another thing coming. I'm a whizz at chemistry."
The more I knew Laura, the more I thought she was very, very cool.
"I'll follow up. I may be a bit of a geek, but I do Judo as well."
"I've got a crossbow," Emily pointed out. "I can shoot from here."
"The truck tyres," Laura advised. "We need to keep them from escaping."
"As you wish."
Two bolts left Emily's little black crossbow in quick succession, puncturing the tyres of the truck on the side we could see. With a hiss of air the tyres deflated.
"We're being attacked!" Toxic cried. She pulled a mobile 'phone from her belt, but Emily shot it from her hand - breaking it in the process, of course. That's the fun thing about mobile 'phones, I guess, villains just buy theirs the same place the rest of us do.
"It's that Girl in Grey's friends!" Toxic cried venemously. "Shoot to kill!"
The result of that was predictable. Emily shot one of Toxic's men through the heart. She's kind of lethal like that.
"Hold them off! I'll plant the poison!"
Toxic and three of her men ran whilst the others tried to hold us off.
We were seriously racing against time!
