Deep in space, a tyrant named frieza had destroyed a planet with one attack killing all its inhabitants or so he thought. The man he stood up to him, his name was bardock was not destroyed with his planet but sent somewhere else by forces beyond frieza power. Whis had transported bardock to another universe instead of letting him get destroyed. A new universe with another earth which held people and titans.
Bardock landed here one night in one of the walled cities on top of a doctors home. He was severly injured yet still breathing. The next morning, Eren stepped out of his house to find a man on the floor next to his house with alot of injuries. Eren took him inside to his father and mother. His mother cleaned the strangers wounds while the father was making medicine to help his body.
"Never seen this guy in town before, I wonder if he is from the outside" said Eren. "That just another reason why you cant join the support corps" said his mother. "You will end up like him or worse"
Right then Bardock was gaining consciouness as lightning struck outside the town. Eren ran outside to check what happened, a giant titan was standing was standing at the wall and starting breaking it. It threw large chunks of the wall into the city and people panicked. One large rock landed right on top of Eren house. Eren ran back to see his family was ok. His mother and father were still in the house along with the stranger. His mother was crying from the house collapsing on her. Her legs were trapped and crushed under the weight. His father was in the same situation. Eren desperately tried to move the pieces off his mother his foster sister Mikasa tried the same with his father it would not move.
The titans has broken into the city. All hope was lost for Eren, then suddenly the house started shacking and moved on top of his mother and father who Eren pulled out. The stranger was no where to be found and they assumed the worst since he was still unconscious.
Then suddenly a man shot out of the house. "That was a rude awakening, where am I?" said Bardock
"I remember fighting frieza now I am here in this city buts thats impossible, frieza destroyed the whole planet"
Then a titan approached the group and picked up Eren mother but before he could eat her something snatched her out of its grasp. It was a the strange man he moved faster than anyone of them to could see.
"If there any killing going to happen here it will be through me" warned bardock as he set down the women. "I didnt do this for you but since he cleaned my wounds I had a debt to pay"
With that bardock incinerated the titan with one blast shocked everyone. The proceeded to fly up and fire multiple key blasts that incinerated all the titans each blast while the power to destroy a continent.
"Looks like you dont need to worry about them anymore, but maybe probably me" bardock gave a evil smirk
