"Greenie"
Peter swung his way up yet another street as he patrolled his home borough of Queens. Stopping at the top a tall building, he paused for a rest and watched the people below. It had been a relatively quiet Saturday, actually. Spider-Man had only found two bicycle thefts and a mugging to stop so far.
Suddenly, a scuffle to his right caught Peter's attention. Cranking his neck, he saw a man with a large knife holding a young woman, the knife pointed at her throat. The man pulled the woman into the alley behind them.
Spider-man leaped into action, swinging down from the roof and toward the alley. What he did not know was that he was not the only one to see the unfolding incident.
When Spider-man dropped down into the alley, a witty quip on the tip of his tongue, he was startled by what he found. The man was already tied up and suspended from a light pole by...thick vines?
Peter's "spidey" senses zeroed in on the two other figures in the alley. One was the was the accosted young woman; the other was another female all in green, helping the victim up from the ground. Her forest green sweatshirt hood was up, hiding her hair and face as she helped the other women fix her hair and clothes.
"Hey!" Spider-Man called. The figure in green started, whirling to face him. A bright green leafy mask obscured her face within the deep hood. He thought he saw her eyes flash bright green as she threw an arm up and more vines appeared out of nowhere, climbing up the building. She grabbed a hanging tendril.
"See the authorities get him, mate?" she asked, her accent unmistakably British. Then she was gone, the vines swinging her away, much like Peter's webbing.
"Hey, Greenie!" he called in vain. "Wait! Who are you?" He sighed and turned to the victim. "You okay ma'am?"
"Yeah," she nodded, "Thanks to her."
Peter looked closely at the vines holding the would-be assailant captive. Hmm...English Ivy?
As soon as the police had the assailant in custody and the young woman and Spider-Man had given their testimonies, Peter slung himself up to the roof of his apartment building and called Tony.
"Mr. Stark, It's Peter...Yeah, I'm fine..." He toyed with the tendril of ivy in his hand. "Well, I think we have another enhanced here in Queens."
