Like many of you, when I first saw Galvatron and later Sixshot, as Headmasters, I was surprised. I didn't mind, since Headmasters were my favorite Transformers figures back in the day. Of course one could reason that the reason they are Headmasters now is due to Hasbro's marketing team dictating that they should be. That's usually the case, when in doubt, blame them.

However, I think the reason that former non-Headmasters are now Headmasters in the Titans Return/Legends line(s), is because they were involved in the Japanese Transformers: Headmasters anime. I have not watched the entire series, just some clips. However, characters such as Galvatron, Ultra Magnus, Blaster, Soundwave, Sixshot, et al, are featured in that series. The characters I just mentioned were not headmasters in that show. However I can see Takara just rolling with the gimmick as reason enough to make new versions of characters from that show.

It wouldn't surprise me to see more figures from Powermasters(from Masterforce), Victory and Zone eventually join the Generations/Legends lines. We already have Overlord on the way and a rumored Deathsaurus. So Star Saber to me is probably inevitable. Scorponok to me, is inevitable, maybe as a leader instead of a Titan.

So I see Titans Return fitting right into the hands of what Takara wants to do with Legends(feature characters from Headmasters the cartoon) and Hasbro(making S3/4/Rebirth characters). So it's a win/win situation for both sides. I hope the gimmick continues because it's pretty fun to me. I think whoever was prominent in any of the later G1 Japanese anime series has a shot in either the Titans Return/Generations line, or the Takara Legends line.

For example, Greatshot? I can see him in the Takara Legends line without getting a release in the Titans Return line. Meanwhile, we are rumored to get Quickswitch in a box set but it'll probably be Six Knight in the Takara Legends line.

 

Neither, just a theory
