The criteria for GA - as opposed to FA - are simply 

    * be well written
    * be factually accurate
    * use a neutral point of view
    * be stable
    * be referenced, and
    * wherever possible, contain images to illustrate it. 
    * Good articles may not be as thorough and detailed as our featured articles, but should not omit any major facets of the topic.

Someone obviously feels that this article meets these criteria. For you to dismiss it out of hand, for reasons that are not required for GA status, and are in fact addressed by the article anyway, and not attempt to make modifications yourself either, is not on.

Cultural context is 1980s popular children's/teen comics derived from cartoons designed to sell plastic toys.
Legacy is the new DH3 series.
Influences are the Transformers series.
Writers are Simon Furman, and Dan Abnett.

This is all quite clear in the article.
