Still has enough power to destroy the Earth after getting his chest sliced open

In a movement too fast for the cyborgs to see, Goku swung his right hand down at 17's body. The Ascended Super Saiyan's fingers, clothed in a violent, jagged aura, slid through 17's torso like newsprint, ripping both his living tissue and metal cybernetic implants. The gash ran six inches deep across 17's entire chest, releasing a violent gush of red blood onto his black shirt and blue jeans.

"17! NO!" the girl cried out frantically. Fear, true fear, had finally revealed to her the truth—it had only come too late.

Goku never flinched, never blinked. His unwavering gaze stared into 17's eyes even as the cyborg began to fall helplessly to the ground, overpowered by nothing more than gravity. Yet even as 17 plummeted, his hardened light blue eyes never showed any remorse. They only inwardly cried out with wrath, with hate. If he could have somehow unleashed what little power he had left, he would have destroyed the entire Earth right then.
