What are the forgotten characters in Dragon Ball?

I think the Dragon Ball has had many roles since it was serialized. However, with the development of the follow-up plot, some early characters seem to suddenly disappear, and no one even mentions them again, except for some that need not be mentioned in the follow-up plot, and some are indeed the reasons why the author forgets them. So which characters in Dragon Ball have been forgotten?

Lan Qi 1

First of all, Lan Qi, a beautiful woman, is a very attractive character in the early Dragon Ball. In addition to her beauty, the setting of dual personality is still fresh in people's memory. After the 23rd First Martial Art School, she left Guixianfu to live with Tianxintang, which was never mentioned before. Only in the TV version of Buou, there is a scene in which the Monkey King receives her vitality. It's a pity that the author forgot this role.

2. Pilaf Trio

The trio of villains in the early stories began to look for the Dragon Ball from the beginning, such as the Monkey King and others. This trio appeared. Last time, it was in Bick Devil. They fished up the rice cooker, drove the Bick devil out, and then were driven off the plane. Not only did they fail to realize their desire to split the world in half, but they were also robbed of a plane by the Bick devil. These three characters are still very interesting, but they are set to create a crisis for the earth. After Bick's article, there is no chance to appear, only in the theatrical version.

3. Crane Immortal and Tauber

The length of time for these two brothers to debut is very short. Tao Baibai was defeated by the Monkey King before the 22nd World First Martial Arts Meeting, but Crane Immortal learned about it at the 22nd World First Martial Arts Meeting, and led the resurrected Tao Baibai to participate in the competition at the 23rd World First Martial Arts Meeting. Later, after Tauber was defeated by Tianxington, Crane Immortal left with Tauber and never appeared again.

4. Divination mother-in-law

Master Roshi's elder sister, is a character with few appearances, but every appearance will bring some help and predictions. In the chapter of Vegeta's coming to Earth, there has been divination for everyone. The last time in the plot was in Buou, where the Monkey King was sent back to the earth to attend the first military congress in the world and Vegeta's meat was released.

Taking your body out of the underworld to fight is one of the forgotten characters.

There is also a role like a king. Except for Bick, other chapters can only be given one shot, which is easy to be forgotten. The key is to be covered by the light of Hercule.
