In the comics, the scene of betrayal was different and took place far from the city, and instead of Clu approaching Flynn and asking if he should still create the perfect system, Clu and the Black Guards just arrive and execute the attack. Originally at the end of this (as shown in TRON: Evolution, TRON: Uprising and TRON: Legacy with the betrayal scene having some minimal differences between the movie, the game and the animated series, but keeping the same context of this moment), besides Dyson being in the shadows commanding the Black Guards, after the coup, Tron is defeated by Clu, Dyson and the Guards, and then, taken and tortured by Dyson (in favor of Clu) before he can escape, as shown in TRON: Uprising. But in TRON: Betrayal, after the attack, Tron finds himself far from the city, in a bad physical condition with some damage done during the coup, after fighting Clu and the Guards. And even in this condition, He is able to activate his Lightcycle and escape.
