Just in off the Asia Tmall retail site, is a poster image from the official Hasbro store that gives us our first look at the alternate spaceship mode of The Thriteen Primes Alpha Trion character, shown below.
This could be based on his Cybertronian Hovercraft design originally created by Casey Coller for IDW Publishing The Transformers: Ironhide comics.
This mode looks like it could be made from the recent alternative mode for Cybertron Sideways, but could be a partial of the Cybertron Starscream. However, Hasbro has stated all of the Thirteen Primes will have new molds, except for Vector Prime what will use the same one released in Legacy United. Only a @markclonus behind the scenes can tell us what this is for sure.
Unfortunately, this doesn't look to be a new figure reveal at this time. The poster is for their "May Day Carnival" event running April 29 to May 5, 2025, which offers an exclusive schoolbag (below) for minimum purchases of 1999 Yuan / $275 USD, or more.
I was initially going to pass on the Alpha Trion figure because some said that it was just going to be a reissue of the Scourge mold. However, now that I have gotten a better look at it... Why do I bother saving money?
