Some might say they are, depending on interpretation. In ancient times, there was a priest Seto, who Seto Kaiba is an apparant reincarnation of. Priest Seto was the secret son of priest Akhenaden, brother to the previous pharaoh, and Yami's uncle. So priest Seto was Yami's cousin.
The main issue is though, is Seto Kaiba actually a blood descendant of priest Seto, or an unrelated (non-family related) reincarnation of him. If he is the former, then technically he is related to Yami. If the latter, then he's probably not.
By their appearance, I would say no.
maybe
I think that what Yugi said that Jaden had lost was fun for the game
yugi came on GX when Jaden tries out for the school and gives him Keribough.
Yami Yugi does. he duels jaden in the last episode i think.
Zane Truesdale is the best duelist!! through out the series as he is the one duelist who actually defeated Jaden , and since Yugi is the king of games ,jaden and yugi are an equal match but Zane's better than Jaden making him the best duelist ovel all . And 5ds duelists don't count at all cuz they all sucks ,they're no match for the real original duelists from Yugioh and Gx series
Jaden Yuki
Yugi
YUGI!
well i say that jaden won but it seemed like it was a win for yugi....boo
yugi defeated jaden in the last and final episode of yugioh gx
I think that what Yugi said that Jaden had lost was fun for the game
nope yugi just manages to beat jaden
yugi moto
yugi came on GX when Jaden tries out for the school and gives him Keribough.
Yusei Fudo meets Yugi Muto and Jaden Yuki in the movie, "Yu-Gi-Oh! 5D's: Super Fusion! Bonds that Transcend Time".
Yami Yugi does. he duels jaden in the last episode i think.
Yugi would! He has Egyptian god cards AND Exodia! Exodia instantly wins when on the field!EGYPTIAN GOD CARDS!
No one's sure of that yet. The ending just shows Jaden showing a pose, and straight after in the desert (after the battle). Most people think Yugi won because of what Jaden said later.
