Doctor Fujiyama the Famous Scientist built a ninja robot, Nightbird, to benefit mankind. However, the Decepticons stole her and reprogrammed her to be evil, so he locked her away for humanity's protection.
3H Wreckers Comic
Decades later, he built an army of them, and for some reason, that didn't go well either. Daniel Witwicky detonated an explosive device to destroy them, killing himself and Wheelie in the process.
He's not a quick learner.
Trivia
In the script for Enter the Nightbird, Dr. Fujiyama's name is consistently spelled "Fujiama," omitting the "y". However, as Fujiyama is (obsolete) Japanese for "Mt. Fuji", it is possible that the episode writer did not know the proper spelling of the word. His name is written as "Fujiyama" in the Wreckers comic.
