Evergreen

I'm gonna take this moment
And make it last forever

In a commercial context, evergreen product is merchandise that is not "seasonal" – it can be sent to shelves for an extended period without needing to be refreshed or updated. For Transformers, this means product that is "franchiseless", not tied to any flavor-of-the-year brand like a cartoon or movie.

After the live-action film series catapulted Transformers back into the public consciousness, deliberately evergreen products became increasingly common throughout the early 2010s, typically for licensed merchandise or for ancillary, value-oriented Hasbro toys. These products would typically borrow key art from a scattershot assortment of sources, such as various Generations toylines and the Legends card game.

Eventually, Hasbro moved to align these sorts of products under a unified evergreen aesthetic, and began implementing a purpose-made set of Generation-1-inspired character designs, created by Emiliano Santalucia, for use on all-and-sundry licensed and in-house products. They debuted in late 2016, without fanfare, in IDW Publishing's contemporary comic line, before showing up on a wider variety of merchandise during 2017.

I'm gonna give my heart away
And pray we'll stay together

IDW Publishing's original Generation 1 comic line began introducing evergreen character designs in the aftermath of the 2016 Revolution crossover event. The implementation was last-minute enough that at least one cover had to be redrawn by the artist to incorporate Optimus's evergreen design. Designs have been introduced as follows:

• Starscream, beginning with The Transformers: Till All Are One #5
• Optimus Prime, beginning with Optimus Prime #1
• Windblade, beginning with First Strike #1
• Soundwave, beginning with First Strike #2
• Shockwave, beginning with Optimus Prime #19
• Bumblebee, beginning with Optimus Prime #22 (in terms of fiction) and Transformers: Unicron #0 (in terms of date of publication).

Space Ape's Transformers: Earth Wars mobile game introduced a design of their own that would be used in 2017:

• Barricade, beginning with "Event Horizon".

Most characters in Cyberverse use evergreen designs.
