Musha Gundam
The series first started on Carddas trading cards with the story set in the "Saddarc World" (Carddas spelt backwards). Soon after it expanded to Gashapons, plastic models, manga and games. The Gundams in the Knight Gundam series are portrayed as living beings just like in the Musha Gundam series. But later on in the series giant robots known as "Kihei"(機兵) were introduced thus creating a weird picture of a Gundam piloting a Gundam. Also different from Musha Gundam, Knight Gundam has important human characters like Knight Amuro and Princess Frau throughout the whole series.
