- Astrotrain won't sleep with anyone who can't fly and he won't sleep with anyone without tank-grade or higher armor. Not flying isn't as limiting as it seems, since all Decepticons have lifters. The armor-restriction is because the engineers get tetchy with him breaking his partners.
- He's bloody tired of people always going for the wings, and he'd rather get his wheels stroked.
- He refuses to be the submissive one in an encounter; he doesn't mind a bit of a tussle or an unclear-dominance if it's someone he's very well acquainted with (Blitzwing), but otherwise, he's the dominant partner.
