Gokou is a boy but in the Japanese version he's voiced by a girl and you can tell. Same with Gohan, Bardock, and Goten. Along with a lot of boys. Goten and Trunks in the American version were girls and you could tell.
Eh I didn't like Cell. I also think Vegeta was a lot more evil when he was. Come on Cell never killed his own partner just because he lost. Sure Cell killed 16 but that was to make Gohan angry and 16 was his enemy. Cell didn't kill Cell Jr's because Gohan beat them, course Gohan killed them so he couldn't but still. Cell also gave them a chance to train so he could have a challenge. I just found Cell annoying.
Trunks came back in time because he thought the only person able to kill the androids and everything was Gokou. He assumed Gokou was the only person who could do it yet the only one who really has the power is Gohan. Also he had the power to stop Cell and Vegeta yet he has to wait until Vegeta gets koed because he doesn't want Vegeta mad at him. Seriously the fate of the world is at stake and he's going to hold back and let Vegeta do something stupid when he could prevent it. That's why I like Chibi Trunks. He has more additude in him. He's more Vegeta while Future Trunks is more Gohan. Course Gohan is also one of my least favorite down there with Gokou, Cell, Zarbon, Freeza and the Ginyu Force..Well except Jeice. I liked Jiece.
