I think fiction could be molded around the toys. I cannot recall seeing too many small Cybertronium space vehicles in the show. Typo, it should have read I do not think any Alt-Mode would help Cosmos evade detection from the Dinobots. Basically, any space vehicle going to/from earth would probably get the attention of the Decepticons, especially when Astrotrain was around. Maybe my optic senses are failing me but where is Cosmos in this episode (check the 7.50-minute mark for an interesting space vehicle transformer)?
