The "Boonboom Legend Bus (Go-Onger Ver.)" comes from Bakuage Sentai Boonboomger (爆上戦隊ブンブンジャー), Toei's 48th Super Sentai series (first aired 3 March 2024), whose team and mecha are built entirely around cars and vehicles. It is not a main mecha or combining robot, but a small collector/edition vehicle from the "Legend Bus" sub-line: a bus-shaped craft in the style of the series' compact "BunBum Cars," designed as a crossover tribute to Engine Sentai Go-onger (2008), which was likewise vehicle- and engine-themed. In-story it is treated as a special BunBum Car carrying the power of the Go-Ongers, tying into Go-On Red's guest appearance in the show. Important for collectors: Boonboomger received no Power Rangers adaptation; this toy was never released as a Power Rangers item and is strictly Japan-exclusive.

In terms of play, the Legend Bus follows the series' core principle: the small vehicles are brought together with the central DX BunBum Changer, which recognizes them and triggers matching, series-accurate sounds and play features. The "Legend Bus" sub-group honors earlier Sentai teams (Legend Sentai) with corresponding paint and deco — here, Go-Onger. The bus has no transformation or combination mechanic of its own like the large DX robots; its appeal lies in the crossover styling and its interaction with the changer.

Manufactured by Bandai (Japan) in 2024, made of plastic (ABS/PVC), in a compact, palm-sized form with no electronics of its own. The distinguishing feature of this particular release: it was a magazine premium (furoku) bundled with the children's magazine Televi-kun (てれびくん), combined June/July/August 2024 issue, released on 26 April 2024. Unlike the standard SG/Shokugan retail versions of the Legend Bus line, the TV-Kun edition is molded in translucent (clear) plastic with Go-Onger deco on the side, clearly setting it apart from the store releases as an exclusive special variant. Compatible with the DX BunBum Changer.
