Super Robot Magazine
From MediaWiki

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 several chapters of a Transformers story called Transformers: The Battle of the Star Gate beginning in #11, but the magazine went under before the story ended.
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 unresolved cliffhanger to fit the 2000 Car Robots in the subsequent gap.
