The Bakuage Sentai Boonboomger Final Lap poster hints at thrilling developments, including the possible return of the Gokaiger team. The iconic flag teases a crossover that could bring exciting alliances or rivalries.
The latest poster for Bakuage Sentai Boonboomger introduces several exciting elements, each hinting at epic developments. Foremost among these is the iconic Gokaiger flag, prominently displayed to tease the return of the beloved space pirate team. While specifics remain under wraps, fans are buzzing about the potential crossover with the Boonboomger. Known for their rebellious and daring nature, Gokaiger’s possible involvement adds a fresh layer of excitement and opens doors for unexpected alliances—or rivalries.

Also front and centre is the looming figure of Waruido Spindo, the boss of the Hashiriyan and primary antagonist, voiced by the talented Koji Yusa. With his distinctive voice and menacing demeanour, Waruido Spindo has been a formidable villain since his introduction to the series. Now, with his ambitions set to reach full throttle, he’s positioned as a formidable force in the Final Lap. His involvement signals that the stakes have never been higher, and he seems more determined than ever to bring his dark vision to life, both on Earth and beyond.
While this poster offers fans a glimpse of the upcoming climax, another poster is set for release next week on November 3rd.
Final Lap Rumours
As Bakuage Sentai BoonBoomger prepares for its highly anticipated Final Lap, rumours about surprise character appearances have been swirling. As above, we already know that Gokaiger will be involved in some form. It is rumoured that both Marvelous and Ahim will both appear. Maybe we might see them do some post Zenkaiger Gokai Changes? Sosuke from Go-Onger is also rumoured to return alongside MachFalcon. It is speculated that this teamup could be tied to the Big Bang Grand Prix (BBGP).
Additionally, there are whispers that Mach Robo will receive new customisations inspired by both Go-Onger and Gokaiger mecha. This might tie in with the new DX Robo universe toy line. We have already seen Mach Robo do this with the ToQger Reesha. So, we could again see “mix and match” forms, blending iconic looks from each team’s style to create new mecha designs. These potential upgrades would align with Boonboomger’s high energy visuals and add even more excitement as the series heads toward its explosive conclusion. With the possibility of Go-On and Gokai customs, Mach Robo might become a visually dynamic tribute to both past Sentai teams, adding to its appeal for longtime fans.
Finally, another major rumour suggests that the 2025 Sentai Red will make their debut as early as January, in a cameo similar to Don Momotaro’s debut on Kikai Sentai Zenkaiger. This rumoured early appearance could come with another thing in store—an additional customisation for Mach Robo, possibly featuring a unique design based on next year’s robo. Should this rumour prove true, it would bring a new layer of anticipation to Boonboomger’s finale, bridging the gap between the current and upcoming seasons in a thrilling way. We have yet to see if these rumours will materialise which ads more excitement to the final set of Boonboomger episodes!
