Donatello had just fallen through a time portal and got transported to the future. Donnie looked around the old lab for a bit before going outside. Then he was ambushed by Foot police.
"PUT YOUR HANDS UP AND DROP YOUR WEAPON" In fear, Donnie put his hands up but then the police got attacked. The police continuously shot at him, and as soon as they ran out of bullets, he attacked.
"MIKEY?" The man stopped and turned around. He only had one arm since he lost his other one from the elbow up. He walked over and yelled at Donnie.
"HOW THE SHELL COULD YOU JUST ABANDON US!?" Donnie looked at him confused.
"What are you talking about? I'd never abandon you guys."
"Well, you left. You've been gone for 30 years..we can't talk here come on, I'm taking you to Master Splinter." They ran through the woods and went into a park. In the park, there was a grave. It was Splinter's grave.
"How-?"
"He died protecting us four from the foot."
"We have to face the shredder"
"That's about as stupid as Mikey 30 years ago." Laila walked up to them, and she was completely different. Her red hair was now red with black highlights, and she had her tongue pierced. Her leg was on a brace.
"Where's Leo and Raph?" Donnie asked and Mikey and Laila laughed lightly.
"Are you kidding me? They got into a big fight a long time ago."
"Well, can anyone get them to meet me?" Mikey turned to Laila.
"Laila, can you get Leo and Raph to meet us at the old warehouse tonight?"
"Leave them to me…" she paused. "Foot police let's go to April's"
When they arrived, April noticed and hugged Donnie tight, Laila was in the other room calling Leo and/or Raph, no one knew exactly who she was talking to, she walked into the room where everyone else was when Baxter Stockman and Hun showed up. Donnie got ready to fight them but April stopped them.
"They're on our side, Donnie"
"We better get going it's getting dark out." Mikey and Donnie nodded and they quickly headed to the old warehouse.
