Ever since Penny was little she'd always remembered her uncle gadget as fun loving and slightly dim-witted. Even when she found out her uncles job she had to admit that she was surprised. He was always inquisitive but she couldn't see him beating up bad guys.
When her parents died and he became her legal guardian she was fascinated by his robotic body with a human heart. She soon became worried about him though, his line of work was dangerous and she was terrified of losing him. So by the time she was eleven she began following him on missions. Penny was surprised at the fact he couldn't really solve the missions. As such Penny always solved them and gave him the credit.
When she turned twelve Gadget enrolled her at the agency where he worked and brought her on missions. He recognized her prodigy mind and told her if she was ever in danger to run as far as possible.
When Penny turned fifteen she and her uncle gadget went on their most dangerous mission yet, only for Penny to be kidnapped.
Her Uncle gadget found her in a MAD layer. That's when Penny saw how clever her uncle was. He had foiled MAD'S schemes and after finding his niece he ran back to headquarters.
At headquarters he had only five minutes to disarm the bomb. He had disarmed every one of them except one. He ran up the third floor corridor and up the stairs, penny hot on his heels. Gadget closed the door and put the entire level on lockdown before Penny could enter. When she reached the doors she could see the bomb counting down from ten. She banged on the doors begging her uncle to get out. Tears streamed down her face as gadget looked at her with resolution in his eyes.
"Penny listen to me I can't disarm the bomb and the only way to stop it from blowing the building up is to lock the floor down from the inside." Penny stared at her uncle wide eyed. He couldn't sacrifice himself he was all she had left.
"Penny I need you to listen ok?, I know you solved all my cases, look I'm not as thick as I portray. I know everything you've done for me. Remember that box? The one you are banned from looking in I need you to look in it."
The clock struck one as the metal panel slid down and blocked Penny's sight of her uncle. She ran away and out of the building as the bang of the bomb could be heard. Penny sunk to the floor as Brian came and Lay next to her, whining for his master. Once the chief said it was safe to enter the building he took penny aside.
"Listen penny we can't find him, not skin or metal, gone inspector gadget seemed to have escaped." Penny couldn't believe the stuff that she was hearing. Was it possible?. Could he have escaped. The thought was almost too much for Penny to bear. She looked at Quimby, "Chief my uncle had sacrificed himself, find me solid proof he has escaped and I'll lead the search but for now I just want to go home." Quimby saw the broken exteriors the girl now had even if she was trying so hard not to show it. As such he got one of his agents to drive her back to Gadgets house.

Penny got in the bath and finally let her emotions loose. Her beloved uncle was dead. DEAD. The uncle that without any experience had raised her from the age of five. The uncle that dressed up as a woman to attempt to cheer Penny up. Granted it didn't help but it made Penny laugh. This was a man who despite being goofy took Penny's first boyfriend aside and threatened him with his life if he dare ever hurt Penny. Penny sobbed as memory after memory entered her head. Everything from finally getting Penny to visit her parent's grave to attempting to help Penny out with homework. Her uncle truly was a great man. At his age and with his job he still found time to raise a five year old with absolutely no experience beforehand. To Penny her uncle was a man of different faces.

Upon getting out of the bath Penny fell into bed and Brian curled up beside her. Penny fell into a terrifying sleep.
