25th Century. The original Bart Allen returns to the main DC universe after Wally West and Barry Allen break the Force Barrier. Once again wearing the Impulse costume, he emerges from the Speed Force and races through a city street triumphantly declaring that he is back. Shortly afterward, he reunites with his former Young Justice and Teen Titans teammates Robin (Tim Drake) and Wonder Girl (Cassandra Sandsmark). Bart is the main driving force behind the revival of the Young Justice team; after being transported to Gemworld and reunited with Superboy (Kon-El), the team officially re-forms.

He has also displayed the ability to create powerful radio waves by rotating his arms at high speeds and using the resulting vibrations in conjunction with his teammate Static's electromagnetic abilities. After Infinite Crisis, Bart's connection to the Speed Force is more difficult to control because he now contains the Speed Force and,
