Your Time: A Transformers/Avengers Story

No Matter The Cost...

Prime, Bumblebee, Natasha and Peter saw the city. Engulfed in fire. Nat was trying to stay cool but Peter was freaking out. Bee looked up at Optimus, "Sir. Our friends?" Prime nodded as he stepped closer to the city. His hand clenched into a fist as he glared at Megatron, sitting on the Avengers Tower holding an Ironman helmet.
"Megatron must be stopped! No matter the cost..." Optimus said as he transformed and drove into the city at full speed. Peter nodded as he started web swinging in and Bumblebee drove with Nat as Prime cleared a path for them. He ran over and hit Decepticons, sending them flying as he transformed and jumped into the air. He pulled out his ion canon as he shot several cons and landed on one of them. Bee drove as Peter lead them to where the Avengers were being kept. They got into a compound as Bee blasted two guards away and started freeing the Avengers, "Hi! I'm Bumblebee! Natasha's best friend!" She giggled as Ratchet ran in with Brawn, "Bumblebee! Thank Primus you're okay! Brawn, help him out" Brawn nodded as he ran over and freed the others. The Avengers nodded at the bots as Ironhide tossed their weapons at them. Tony and Rhodey got suited up as Cap grabbed his shield as they walked outside, "Avengers! Light 'em up!" Tony shouted as the avengers ran or flew out firing and trying to bring down the Decepticons. Ironhide, Brawn and Ultra Magnus punched their way through the cons as the others followed behind. Bee and Nat ran as they reached Oscorp Tower where Megatronstood ready to bring Cybertron to Earth. "By Primus! He'll destroy the earth!" Bee shouted as Peter ran past them, "Not if we got anything to say about it!" he shouted as he scaled the building. Nat nodded at Bee as he threw her up into the air. He started parkouring his way up as Natasha landed on the top. Peter stood with her as Bee landed behind them. Megatron turned around and snarled as he aimed his fusion canon at the three of them. They jumped out of the way as Bee activated his battle-mask and sword and lashed at Megatron, Peter tried webbing Megatron down as Natasha fired all she had at his face. Megatron grunted as he grabbed Bee and threw him at Nat. Peter caught Bee as he nodded and fired at Megatron. Peter ran and tried punching Megatron, "Not today bucket-head!" he shouted as Megatron grabbed him and threw him into the ground. He kicked Natasha into a wall as Bee ran at him. Megatron growled as he grabbed him and slammed him into the ground, he aimed his canon as he smiled devilishly as Natasha and Peter scream, "NO!" Megatron's canon went off but Bee was still alive. The two Spiders looked up and realized Optimus arrived in the nick of time. Megatron's optics widened as Prime glared at him, "Don't...Touch...My friends..." He grabbed Megatron and threw him into the space bridge activator as it blew up. The roof began to blow as Prime grabbed Bee and the others, he started running off the tower as Peter held on to him and Natasha tightly. He jumped as he started falling. The Avengers watched with shock until some planes flew in, "From one ship-!" Powerglide said as he grabbed Bee, "To another-!" Skyfire said as he flew in and Jazz shot a grapple hook at Peter who caught it and was able to get him and Nat to safety, "No big deal!" Swoop shouted as he grabbed Optimus and threw him to Grimlock. He jumped and caught Prime as he shouted, "ME GRIMLOCK GOT PRIME ON IT!" Everyone cheered as the Decepticons and Megatron retreated from the battle. 

The Avengers relaxed as they sat and talked. Natasha sat alone until Prime and Bee sat with her. She smiled at them and then sighed. "Is this the part where you and the others leave?" she asked Optimus. He and Bee looked at each other as they looked down at her, "Megatron is still out there, and as long as he remains, we stand a better chance of victory with you and the Avengers." She smiled and turned to Bumblebee, "I'll stay if I become your guardian robot." She nodded and hugged him tightly. He hugged her back as all the others walked up to them. They smiled and looked up to the stars. More comets came raining down. One landed in front of them as an Autobot emerged and winked at them.
