Gwen Tennyson was waiting for Kevin and Ben at Mr. Smoothies. She was hoping that nothing could ruin this peaceful day.
But Gwen was dead wrong. She noticed some trouble going on nearby.
Gwen said, "I wonder what's going on over there." She went over to investigate.
Once Gwen came over there, she asked, "Okay. What's going on here?"
A crook in a ski mask was running in her direction with a suspicious looking briefcase. But Gwen stood in his path. The crook snarled, "Get out of my way, girlie! Or I'll snap your neck!"
Gwen said with a glare, ""I don't think so." She then threw a mana disc at the crook.
Before Gwen knew it, the crook was already knocked out. Gwen spotted the briefcase and asked, "Now what could be so important in that briefcase?"
Gwen opened the briefcase. Inside was a green vial. She said, "It's some kind of liquid. But I wonder what it does."
Gwen drank the vial. She makes a face and said, "That stuff didn't taste so good. Well, I better go back to Mr. Smoothy's. Ben and Kevin must be there by now." She then walked back to Mr. Smoothies.
Ben and Kevin were already sitting at their table by the time Gwen got back to Mr. Smoothy's. Ben said, "Hey, Gwen. You having a good day?"
"Yes, I am," was her response.As Gwen sat herself down, Kevin decided to tell a joke. He said to Ben and Gwen, "Hey, guys. I've got a joke for you two. How do you make a tissue dance?"
Gwen and Ben just groaned.
Kevin said, "You put a little boogie in it!" With that, Kevin laughed. But Gwen said while drinking her smoothie, "That joke isn't that funny, Kevin."
Kevin told Gwen, ""Chill, Gwen. It's just a joke."
Gwen growled, "And I'm saying that it's not that funny!" Ben and Kevin were shocked at this sudden display of anger. Gwen then said with an apologetic look, "Sorry, guys. I don't know why I'm feeling angry all of a sudden. I was in a good mood this morning."
That's when Ben noticed something. The Ultimatrix Wielder asked his cousin, "Is it just me or are your eyes greener then usual?"
Gwen asked in shock, "What?"
Ben said, "I'm not kidding, Gwen. Your eyes are really glowing green!"
Gwen goes to a mirror to see her eyes glowing green.
Gwen said, "Oh God! I think this has something to do with that formula that I drank earlier!"Kevin then realized something. He asked Gwen, "Gwen. That formula that you drank. What did it look like?"
She describes, "Well, it was green."
Kevin told her, "Gwen, that was the Hulk formula that you drank!"Ben asked, "Hulk formula?"Kevin explained, "It's a formula that the Plumbers have been tracking for a while now. Whoever drinks it will turn into a creature like the Hulk."Gwen said with a worried look, "Oh no. Will the formula affect my mind?"
Kevin replied, "You'll still have your mind, Gwen. But you'll need a change of clothes after the transformation's done. Ben, can you turn into Xlr8 and get some of Gwen's extra clothes from her house?""Will do," Ben turns Xlr8 and speeds away.
After that, Kevin said to Gwen, "Do you feel anything else changing besides your eyes?"
"My skin is turning green," was her response while looking at her hands.
Kevin told her, "Gwen, I need you to stay calm. Okay? I'll be with you the entire time you transform."
Gwen said, "I'll try. Now I know how you felt whenever you got mutated in the past."
Gwen grits her teeth as her transformation continued. Her hair tie snapped off causing her hair lose its ponytail state. Gwen now has her hair down. Her hair then lengthened down her back. Gwen said, "I haven't had my hair down for a while. Do you think it looks good on me, Kevin?"
Kevin smiled and said, "Of course it looks good."Kevin took out his Plumber's Badge and contacted Ben through the Ultimatrix. He asked Ben, "Ben, where are you right now?"
Ben replied, "Don't worry, Kevin! I'm going through Gwen's spare clothes right now!"Kevin said, "Your cousin, who's also my girlfriend, is going through a transformation that might scar her for life. And you're telling me not to worry?"
Ben said, "Cool your jets. I'll be right there."
Kevin said, "Alright. When you get back here, can you go Four Arms in case we have to calm Gwen down after her transformation?"
Ben replied, "That's the plan."
After Kevin hangs up, Gwen groans in pain as her hair turned green. She said, "Oh God! I look like a freak right now!"
"Don't worry, Gwen. Everything will be fine. I promise," he reassured her.
Gwen replied, "I hope so." Just then her clothes started to tighten right before Xlr8 zoomed by with Gwen's extra clothes.
Xlr8 said, "I haven't used Xlr8 for a long time. Kevin, how's Gwen doing with her transformation?"
"So far, her eyes and skin are green. Her clothes are now becoming tight on her."
Xlr8 placed Gwen's clothes on a nearby table before turning into Four Arms. After that, Gwen's high heels ripped off of her expanding feet. She said to Four Arms, "Go ahead and make fun of me now, Ben. I look absolutely hideous!"
Four Arms frowned and said, "Gwen, I would never make fun of you! Okay, maybe I have made fun of you before. But what makes you think I'll do it now?"
Before Gwen could reply, her skirt started to rip a little. But it still stayed on. Gwen said, "It's a good thing my skirt's staying on."
Four Arms said, "Of course it's a good thing."
Gwen's stocks then ripped off, revealing her green legs. Gwen asked, "Do you think I'll still have my Anodite powers?"
Kevin said, "Don't worry. I'm sure you'll still have them.
Gwen's sleeves then ripped apart. She then asked Kevin and Ben, "Is the transformation over?"
Four Arms said, "Yeah. I think your transformation's just about over. How do you feel about your new form?"
Gwen replied with a smile, "I actually like my new form. Now I know how you feel whenever you go alien! But I'm considering on getting a leotard for myself whenever I transform. What kind of leotard should I get?"
Kevin replied, "You should get a blue leotard."
Gwen said, "Good to know. Alright, I'm going to change back into my human form. When I do, I want one of you to hand me my spare clothes, okay?"
Kevin and Four Arms both said, "Got it."
Gwen closed her eyes and concentrated on her human form. Sure enough, her body started to shrink. Her skin pigment turned normal. Gwen's hair began to grow shorter before turning back into an orange color. Then her muscles began to shrink. Gwen's eyes returned to normal, finishing her transformation as Four Arms turned back into Ben. Gwen groaned as she stumbled forward but Ben caught her. Gwen said, "Thanks, Ben."
Gwen then dressed up into her spare clothes after Kevin handed them to her. A few minutes later, Gwen was wearing her spare clothes. She was wearing a white shirt under a dark blue sweater, black stockings under a black mini skirt, and black high heels. Kevin said, "Haven't seen you in that outfit for a while. You should wear it more often."
Gwen smiled and said, "Thanks."
Little did they know that Gwen's new powers would come in handy in the upcoming battles.
