The Diesel Basra is one of two main antagonists (the other is a Steam Locomotive Jamen) in episode 14 of 2020 TV series Mashin Sentai Kiramager. It's a Diesel Locomotive-based Basra Type Jamen Beast of the Dark Empire Yodonheim, released from the invasion gate created from the dark energy gathered by Steam Locomotive Jamen.
The Diesel Basra made its first appearance alongside the Sl Jamen who's piloting the Smog Jouki prompting the team to bring out Kiramazin to battle these two monsters.
After the accidental destruction of its master the Diesel Basra used one of its ability as it sprayed the oil at the mechas.
Thankfully with Juru's inspiration he transformed Duston from a garbage truck into a vacuum cleaner as it suck up all the oil spill that the Diesel Basra has made along with the mask thus revealing the monster itself to be Guesra.
After that clean up it was then destroyed by these two finishers which are Kiramai Dynamic and King Express: Burn Blaster.
- The Diesel Basra is the first train-themed monster since Yokai Wanyūdō from 2015 TV series called Shuriken Sentai Ninninger.
- The Diesel Basra is the second Jamen Beast to appear unmasked (after its Jamen was destroyed in battle). The first being a Rugger Ligany (whose Jamen was seen being put on during its appearance).
