With his now Blue Smack hands Rex landed one massive punch to Cosmos stomach making her slide back as he changed to his boogie pack as she yelled, "YOU LITTLE BRAT MAMA IS GOING TO HAVE TO BRAKE OUT HER BELT!" she summoned a dark magic whip and tried to strike him but rex was avoid it.

his turrets then turned and fired off their cable weights landed two hits to her eyes making her cover them and yell in pain.

that is when he landed on a ruined building and changed to Slam cannon and fired hitting her in the neck making her gasp for air and hold that while blinded as she called out, "How can you hurt your mama like this!?

Rex summoned the Rex ride and drove off at high speed with the ham hitting her foot with knocked her down as he flipped changing to Punk busters with he used to high kick her in the gut as she fell and he said, "My mom has been dead and gone along time lady!"

the kick made Cosmos spin as she hit the ground face first and Rex changed to Big fat sword like all his builds it was now blue as he set it ot buzz saw mode and charged as she got up slashing her stomach leaving a wound.

She screamed and hit the ground the quake knocking Rex back so he switched form sword buzz saw to Blast charger. His whip arm grabbed Cosmos finger letting Rex Swing to a roof while shocking her making her roar in pain.

Once on the roof he changed to funchucks and jumped off landing to impact strikes on her back between the wings making the goddess of Chaos scream in pain as she yelled out, "HOW COULD A RAISE SUCH A BRAT!" she said as her sight returned, turning her neck at a horrifying angle to look at him and spit a fireball

Rex charged changing to badaxes as he slashed through the Flames jumped and landed a left Axe slash to her eye and he jumped off her head making the Block party build with both arms.

he smirked as he fell landing right on her foot making her scream in pain form it as he rolled off and got to his feet, "I was expecting more a challenge!" He build the sky slider and charged at high speed for her scare!

Cosmos roared and made an energy barrier around her only for her eyes to widen as midflight Rex took on his omage Evo form and land a left hook that smashed her barrier and hit her chest wound.

the impact made Cosmos gasp as Zecora big mac, Twilight, Luna and Celestia were knocked out of the fusion leaving Original Cosmos standing holding her gut her injuries gone but she was stunned looking at her son.

Watching form the base was most providence and most of the ponies Scootaloo blinked, "Please do the thing please do it!"

Rex put his fist together and fired them off like rockets and she said, "YES HE DID THE THING!" The impact seemed to send Cosmos flying back as new hands grow on the omega Rex who charged.

Pinkie pie who was still a normal pony was dressed in a cheer leader outfit with her still normal pony friends other then twilight cheering, "Rex rex your discords son if you can't do it we're all bucked!"

Discord looked at them and said, "Gee why to not put pressure on the boy!"

Meanwhile back with the fight Cosmos growled as he summoned her whip and landed a hit to Rex's robot chest making it turn purple and black as she landed other whip strikes on to his left shoulder leaving the arm limb and hanging, then the leg freezing it.

she kept doing it as she said, "Ok Mommy underestimated you but you still can't beat her!"

the next thing she did was hit her son in the head making his Giant robot form shatter leaving Rex in am impact creator struggling to get up but he stood shaking as he made the smack hands and was still trying to fight.

he went in the fist spinning but Cosmos vanished and appeared behind him at his size, "Mommy isn't going to make the mistake of being a giant target again Rex honey!"

he turned left arm block party right arm buzz saw mode Big fat sword trying to slash her but she vanished appeared behind him and held out her clawed hand shocking him with purple lighting.

Rex screamed is builds dropping as he fell to his knees as his mother stopped shocking him as she said, "proud of you standing up for what you believe in but it was against mommy so you most still be punished!"

that is when out of nowhere Caesar mobile lab crashed on it her exploding knocking Rex away.

Only for the Armored but no helmet Caesar to grab him and hold out the bell as he said, "I don't think so Mom!" in a moment the bell glow as did she making her scream as it drained her magic.

when it was over she held out her hand to try and shock them but nothing and Caesar smirked, "the bell stole your magic you don't have power anymore your just a normal funny looking Evo!"

Rex got up standing but shaking as he held out his hand, "that means she can be cured!"

Cosmos held her hands out, "boys boys it's been thousand of years for mommy doing that would make her look her age and turn her to dust!" In a moment Caesar used his machine to make a sound only Cosmos could hear so she fell over in pain as he said, "our mom has been dead longer then that!"

Rex then managed one more jump grabbing on to Cosmos as the circuit boards appeared as she cried saying, "I just want my family back!"

the Teen hero looked tired and beaten as he said, "we know but the way you did it make sure it won't happen!" before long Cosmos was gone literal dust in the wind.

As he passed out the ruins of the cities seemed to repair themselves as Discord and a now normal Fluttershy showed up and discord picked up Rex, "well Sons you did it!"

Meanwhile escaping the repairing prison was Van Kliess as he took pill making his robotic arm regrow as he smiled " well let's continue our dance Rex!"

A week later.

Rex was waking up to see Lioness cuddling on top of him opening her eyes and happily hugging her boyfriend, "your wake you been out for a week GIRLS COME QUIT REX IS UP!"

Scootaloo ran in tackling and joining the hug as apple Bloom in tears came in joining it followed by a smiling Sweetie belle.

Rex blinked, "A week is everyone ok!?"

Lioness kissed him and said, "yes everyone is fine the ponies are all anthros and it's a new world that need it's hero and Kliess escaped."

the hero rolled his eyes, "I figured as much Well at least this adventure is over now can you girls let go and help me up I am so very hungry! I could wipeout a taco truck right now!"

discord smiled, "the adventure continues but the story doesn't!"

an anthro Fluttershy in a wedding dress smiled, "I am so proud of my step sons for stopping their evil birth mom!" she then kissed her husband discord.
