This time we have another 2-part web comic/manga which continues the story after the events at the end of God Nepturne story (which you can find an English translation here). The Dinobots arrive as reinforcements summoned by Primus. Several of the latest Micro Masters and Battle Masters can be seen like Soundbarrier, Doublecrosser and Rung among others.
We learn about what happened to the Dinobots before their arrival. They were on an island together with POTP Slash and Grimmaster (PCC Grimstone redeco) when they are suddenly attacked by the Quintessons and their Allicons (Earthrise molds). Odds are not in favor of our heroes when Predaking appears, and not even Grimmaster in combiner mode is enough to face the Decepticon gestalt. Grimlock takes out 2 massive swords and attach them into his back like wings and attacks Predaking. All classic G1 Dinobot finally combine into Volcanicus to defeat Predaking.
