Chapter 1: The beginning of the dark tomorrow
A boy is seen running through the clear forested area in a distressing hurry. This boy is Gohan son of Goku and ChiChi, whom the latter is ill as the reason gohan is rushing to his home. As he is heading home he sensed other presences and turned to see who it was and saw the two people he considered his friends. One is a red manta like creature with a green hour glass symbol on it's chest the other is a girl with blond hair wearing a red skirt, red boots, and a tight blue shirt with a shielded 'S', they are the heroes' ben 10 and supergirl as they caught up to gohan.
Gohan first spoke "ben, Kara what are you doing here?" he asked.
"Well we heard that your dad was ill and thought to come over check on you guys." Said ben knowing how much gohan cared for his father.
Kara nodded in agreement "yeah my cousin and the others are at your house to see what they can do for goku."
Gohan smiled in appreciation "thanks guys, you're the best". He said but went to back to serious. "Well, we gotta hurry then."
Ben and kara nodded went and picked up speed with gohan to the destination. Meanwhile at the Son house, everyone was present from the Z-fighters, Justice League, team 10, and TMNT. They were in silence despite the wailing of six month old trunks and one-year-old shadow Jones, they were standing there waiting for three people to show then oolong and puar sees the three.
"Hey it's gohan, kara, and ben" shouted oolong as the others notice of their appearance. But gohan ran in to the house with ben and kara in tow. Once the trio ran to the bedroom they three people other than gohan's family, one is man in his late 60's he is Max Tennyson grandfather of Ben, right next to him is a broad man in a blue suit that has s-shield on his chest with armor patches and a red cape. He is Clark Kent otherwise known as Superman, next to the lying goku is a human sized in a brown kimono he is known as splinter father figure and teacher to the turtles. Right now all of them have solemn look while ChiChi was crying over her husband.
"Oh Gohan I'm so sorry" she said mourning over now dead husband.
All three in the room were shocked gohan more so as he realized he can't feel his father's energy.
"y-you mean goku is…" said ben in disbelief.
"That can't be true can it?" Asked kara as tears were forming from her eyes as covered her hand with her mouth.
Max and superman gave them a remorse look while splinter had his head down.
"Yeah I'm afraid it is kids." Max sad in pure sadness knowing goku since he met him as a child. Kara cried her eyes out as clark hugged her in comfort while ben stood there in shock.
Outside the house they all sensed it especially krillon.
"He's gone... Goku's gone." Exclaimed krillon as everyone was shocked by this development as their lifelong friend passed away. They expressed this in their own way with tears and silence.
Kakarot… no. Vegeta muttered in shock while rapheal gritted his teeth and to the for a clearing and stopped and fell to his knees.
No no…NOOO! Shouted Raph with every fiber in his being unable to handle the lost of the person who truly accept who and what his family was from the day they met.
A tragedy in this day as Goku has succumb to an unknown heart illness and has left his friends and loved ones behinds. But this was the beginning as another dark event will fall to the world.
