The Transformers KT Figure Collection, put out by a co-brand of Kaiyodo and Takara in 2004, consists of 5 figures and an exclusive. Captain Kyle goes through the 5 figures, including one that is very different than the other 4. The exclusive is not in this video and is a repaint of one of the main figures.
Released in 2004, this collection consists of a mini-bust of Autobot leader Optimus Prime, or Convoy as he’s called in Japan, Decepticons Frenzy and Rumble using their piledrivers, a diorama inspired from Transformers the Movie with Devastator breaking through a wall to confront Arcee and Hot Rod, and finally another diorama featuring Ai-chan (known as Tai in the US) taking a bath. This last figure is the only one not featuring Generation One characters and is very different in tone as well. Why a hologram would take a bath is something that puzzles Captain Kyle and likely everyone else familiar with the character. This non-transforming set is definitely an oddity.
The exclusive, which is not featured, is a silver repaint of the Optimus Prime mini-bust in order to represent the special metallic coating that he used in “The Return of Optimus Prime Part 2” to avoid being infected by the hate plague.
