Dragon Ball GT and Z have feats in the range of quadrillions of times the speed of light, such as the genki bubbles from the Spirit Bomb crossing the universe within ~50 seconds and Pan and Oob dodging them, Cell's Kamehameha outspeeding Goku's Instant Transmission (which showed the ability to travel to the edge of the universe within one minute), Dr. Raichi's warriors traveling from a planet on the end of the universe to Earth (which is stated in the Hirudegarn movie to be on the edge of the universe, which means they crossed the entire universe to reach Earth), Kid Boo's ki blast circling the entirety of the Kaioshin Kai, which is billions of light years, within a few seconds....there are too many to count, and that's if you don't count Dragon Ball Super, which also has stuff like Whis traveling from Beerus's planet to Earth in ten seconds,.
