New Characters:
Ultra Namek-jin Piccolo: Combined with Kami-sama, Piccolo is faster and stronger. Physically the same.Other Notes:Second-Stage Cell: After consuming #17, Cell looks a little more human, and is a lot more powerful. Ultra Saiya-jin Vejita: Stronger, but not much different.
Ultra Saiya-jin Trunks: Stronger than Vejita, and doesn't use his sword anymore.
The Room of Spirit and Time: This is the room at Kami-sama's location (at the top of Karin Tower) where 1 year inside equals 24 hours of real time. The gravity is 10 times Earth's, and the air is 1/4 Earth's density. In here, when a Saiya-jin trains, the Saiya-jin's rage can cause him to reach the next level of power (ie -- from a Super Saiya-jin to an Ultra Super Saiya-jin.) Normally, there is a house (normally equipt) which is surrounded by white space as far as one can see. The white-space area is about the size of Earth. Lastly, there is a 48 hour time-limit on the Room; if someone stays inside longer, the door disappears and that person becomes trapped. Originally, no one was ever able to last a full year in the room, but Trunks, Vejita, and Piccolo all last that long while training for the Cell Game. In fact, Vejita returns to the room several times over the 9 days prior to the Cell Game. (The first time, Gokuu could only last 1 month, the second time, he and Gohan only need to be in the room for about 10 months.)Super Saiya-jin: This was supposedly a legendary power level. The last time this had happened was on the Saiya planet, 1000 years before. Then, Gokuu, Vejita, and Trunks all become Super Saiya-jin within a couple of years. With volume 31, comes the introduction of the idea that the heroes can go beyond Super Saiya-jin to become something else. (Ultra Super Saiya-jin, I guess.)
