Kagato is without a shadow of a doubt the coolest character in the series. He does everything with style. Through his intellect he has managed to make himself very powerful. His main goal is to assimilate with Tsunami and take her power as his own. He tried once 700 years ago when he sent Ryoko to capture Tsunami but that attempt failed.

Kagato was a student of Washu's backed in the day. Using his intelligence and some of Washu's inventions he managed to capture her, steal the Soja, and control Ryoko. He then proceeded to steal rare artifacts, and destroy. He is one of the few that truly understand the gems that Ryoko owns. using this understanding he was able to create gems that were much more powerful, though they were much larger, so he mounted them on the Soja.

When Kagato came to earth he came to get the secret of Tsunami from Aeka. He then captured Ryoko and Tenchi and company give chase. Tenchi "died" on the way and the girls went to take revenge. Later, after the battle Tenchi defeats him.

In the TV series Kagato appears once more, though not as powerful as the OVA Kagato, he was pretty much a push over. Back in the day he and yosho were the most powerful knights of Jurai. One day he went mad, and Yosho had to defeat him. He did not die as the evil within him kept him alive. When he met the group late in teh TV series he defeated Yosho and captured Aeka. tenchi then recieved the sword and later kill Kagato in a roughly 2-3 minnute battle.
