Why They are Forgotten
This section is here to show the not so obvious reasons why these characters are the Forgotten Warriors
Never Got to use Their Power

Tien, Yamcha, and Chiaotzu trained with King Kai and became much stronger, but they never got to use this new power.  Yes, they beat up the Ginyu Force after they were already dead.  When they were brought back to life nothing happened except the Garlic Jr. saga were Yamcha was the only one there and he was infected by the black water mist.  By the Trunks saga everyone had surpassed them once again.
Stronger than Vegeta

At one point, I believe, that Tien and Yamcha were stronger than Vegeta.  Vegeta got beat up by Recoome and Yamcha beat Recoome.  Even though by the time they fought the Ginyu Force Vegeta was much stronger I think at the time Vegeta got beat up by Recoome Yamcha was probably still strong enough to beat Recoome.  Just something else nobody thinks about.
Better than Krillin

Krillin is not a bad guy, but the thing I get sick of is people saying he is the strongest human.  I also get sick of people saying Yamcha is a wuss and not Krillin.  (Sit back this may take a while)
First off, I don't know how Krillin can be stronger than Yamcha and Tien when he never trained with King Kai.  On Kami's lookout he, while Tien and Yamcha were fiercely battling each other, he got beat up by Yajirobe while he was eating some corn.  He was killed before either of them in the pendulum room.  After one kick from Recoome he layed there and didn't get back up until Goku arrived with a senzu bean.  During the ten day waiting period for the Cell Games Yamcha and Krillin go outside to train and Yamcha beats him up.  As for being a wuss, the one time Androids 17 and 18 were fighting everybody including Yamcha and Tien, he stood back there too scared to move.  When Cell and Gohan were in the last power struggle Piccolo went to try and help, then Tien and Yamcha, and a little while later Krillin decided to finally go.

In the fight with Cell, Piccolo, Tenshinhan, and Yamcha get up three times and Krillin only gets up twice.  Krillin didn't lay one hand on Cell Jrs, Yamcha and Tenshinhan saved Goku's life.  Yamcha and Tenshinhan were the final guys in the Pendulum room and they got good hits on those 2 Saiyans.  Krillin's an idiot, he attacks Majin Buu head on and doesn't tell Yamcha, who could've helped and maybe Krillin could have lasted longer.  Krillin got treated like a ping pong ball against Chiaotzu in the 22nd tournament, though Yamcha got beat by Tenshinhan he put up an awesome fight, also Krillin would have got torn apart by Tenshinhan. Yamcha trained harder than Krillin in the Buu saga.  Yamcha battled almost all the warriors on Grand Kais planet.  Krillin watched him and said, "Ow man, I thought he gave that up..."
