Super Robot Magazine
From Transformers Wiki
Super Robot Magazine (スーパーロボットマガジン) was a Japanese comic magazine published by Futabasha. In 2003, it published a four-part Transformers story called Transformers: The Battle of the Star Gate beginning in #11. The magazine went under with #14, ending right as the story concluded.
In 2006-07, TakaraTomy officially placed that story within the Japanese Generation 1 cartoon timeline, moving its events to the late 90s and using its ending to fit the 2000 Car Robots series in the subsequent gap.
