The sequel to SD Gundam Gaiden Knights Of The Round Table, SD Gundam Gaiden: Seikihei Monogatari is a Cardass series in the Knight Gundam series released in 1992.
The Zeon Clan from SD Gundam Gaiden: Sieg Zeon Hen have been resurrected as the Neo Zeon Clan, and are attacking the kingdom of Dabat! Being chosen by Holy Machine Soldier Gunrex, Knight Gundam GP01 must now fight to protect both the kingdom and the Saddrac World!
Tropes associated with SD Gundam Gaiden: Seikihei Monogatari are:
- The Bus Came Back: Characters from Sieg Zeon Hen come back for this story. Characters from Knights of the Round Table do too, but that's less exciting as that was the prior story.
- The Chooser of The One: Gunrex is the one who decides that Knight Gundam GP01 is the chosen one.
- Decoy Protagonist: In the first arc of the series, it is implied that Burning Knight F91 would be the protagonist as he is the character focused on in the beginning and is the one to first pilot Gunrex. This changes after he is put into a coma from Evil Machine Soldier Dark Tyrant's attack. The real protagonist is actually GP01, Heavy Knight GP02's squire.
- Humongous Mecha: The Kihei, large machine soldiers that can be piloted by the SD Gundams (The irony of SD Gundams piloting Giant Mecha should be noted).
