A/N

I am super pumped for Across the Second Dimension so much that I've been coming up with ideas for it and imagining about Perry helping his alter self break free of Alter Doofy's control.

At the moment this is just an one-shot but it could be the beginning of something more.


Alter Doof cackled as he was watching both Alter Perry and the other Perry fight but Phineas along with Doofy was scared knowing both platypi didn't want to fight but Alter Perry had no choice as he was blocking Perry's blows but realised he was holding back.

"Why so afraid to fight me?

Afraid I'm the better egg laying mammal?

I thought you were an agent." he mocked.

Perry was holding back as he didn't want to hurt his alter self but saw him hesitate making him curious.

"I know you don't want to hurt me.

I can sense it in your aura." he told his alter self.

Alter Doof was nervous knowing this Perry wouldn't bend to his will like the Perry in this dimension but he noticed both platypu had stopped fighting.

"Why would you help Alter Doofy?

He took over this dimension!" Perry demanded.

Perry's alter self shook hearing that.

But he had a feeling he cared about him.

"i helped because nobody cares about me anymore.

When my Phineas and Ferb found out about my double life, they hated me.

So I left and turned to the one person I thought would help.

But I was so wrong.

He used his newfound sills to rnforce his will on me.

Then I helped him take over.

I'm so sorry!

I just wanted my life back!" he said sniffling.

Both Doof and Perry felt bad for this Alter Perry.

Doof then hugged him making Perry smile.

But Alter Doofy saw that his litle servant was beginning to break free.

"You obet me!

Now finish him!" Alter Doof ordered.

"N-No, No I won't.

Not anymore.

I want my life back.

You lied Doofus." he replied finding his voice.

Perry smiled hugging him.

"I'll take care of him.

His invention is what messed this dimension up.

I need your help.

But maybe Doofy can too.

He could distract Alter Doof for us." he told him.

"What about us?" Phineas asked.

Perry shook his head.

"No Phineas.

This is too dangerous for you to help.

I couldn't bear it if you got hurt or worse.

I can handle him.

It's been my life since I was hatched." he ordered.

Phineas then hugged him.

"Good luck." he whispered.

Perry smiled breaking the hug.

He smiled broadly seeing Alter Perry disabling Doofy's machine.

But he then helped destroy the inator but suddenly a vortex appeared as Alter Doof was scared knowing it would take them back to their dimension but Phineas was scared.

"It'll be okay Phineas.

I'm not gonna lose you again." Perry told him.

He then activated the hover car but saw Alter Perry in there but smiled.

"Come on guys let's go!" Perry said driving.

Doof was hugging Alter Perry as they went through the wormhole...
