Hmm... the name Gobuster had me expecting a Ghostbusters knockoff, but the villain sounds like RPM's Venjix program instead. And the mecha are very complicated, with multiple layers of combination and transformation. Sentai mecha usually tend to be either animal-based or vehicle-based, and Go-onger tried to do things that were both at once, but this one seems to be doing both separately and simultaneously. I don't see that as either feasible or desirable. There was no mention of Venjix here, nor of this "Professor Cog" character in RPM's continuity. And there was certainly no casual use of an interdimensional subway train in RPM. Also, other posters have pointed out the contradiction about the breathability of the air; in RPM we saw plenty of characters surviving without helmets outside the dome.
