TJ fights by using his normal strength now instead of the implants that was given to him by Ultratech. He was bribed to lose to the new Fulgore line (the KI1 model). However, he said "No way" because of fans, and UT exposed him for the fraud he was. I don't remember the Riptor he killed, but he probably can take on more than one as he did via cutscenes and probably that storyline they're making.
Balrog did kill one of Dhalsim's elephant, and that's pretty impressive considering how much electricity was used to kill one in some old experiment. Also, he did punch a moving car with one punch in the SFxT video:
