1) Something this character is truly proud of
I think he’s genuinely proud of a lot of his schemes. The one that springs to mind was his hacking of Earth Defence Command during the hunt for the Enigma of Combination back in ex-RiD; there was just something so smug in the way Prowl related reading the general’s emails while he was in there for the hell of it. 😀 In a broader sense, I think Prowl’s proud of having the kind of mind that allows him to come up with such schemes. It’s a burden, but also a gift.
2) Who they want to please the most
Hmmm… difficult. I actually don’t think Prowl wants to please anyone anymore. At one point, it was definitely Tumbler, but now, pleasing anyone takes a back seat to the Cause. In fact, I think he’s gotten to the point where if people are happy with him (especially if those people are Optimus), he thinks he’s doing something wrong.
Oh – I do think that while he was bonded to the Constructicons, it felt treacherously good to make them happy (because it would ripple backwards and forwards across the bond and amplify), and he hated that because it was this foreign impulse he felt had been forced on him.
Prowl does have his moments, though. I think the last person he genuinely wanted to please, even just in a small way, was probably Fort Max, and before that, Springer. And before that, Ironfist. (Yes, that was Prowl being manipulative, but he also genuinely thought he was doing a kind thing.)
7) This character’s favorite character
Even after all these years – I think it’s still Chromedome. Four million years after they broke up, Prowl still depends on him enough that he tells Chromedome in the first issue of MTMTE, “I can’t do without you.” And I don’t think he just means for his mnemosurgery talents, either.
I also think Chromedome represents a piece of Prowl’s past, back when he was… more innocent, maybe. Untainted. He’s fond of his agents (Jazz, Skids, and Getaway especially), and he’s genuinely friends with Perceptor and seems to have been with Bee, once, and he’s got complex, tangled, intimate relationships with Impactor and Springer and Mesothalus and the Constructicons and Arcee – but all of that came during or after the war. Those connections were made by cold, calculating Prowl who never really turned off the “what can I use this person for” running tally in the back of his head. The Prowl who first fell in love with Tumbler was Prowl the sweet, geeky detective who’d never been in a fight, and I think present-day Prowl – as much as he’d consciously deny it – values that link to his past on some level.
17) What they’d sing at karaoke
Oh, gosh. I kind of think it would depend on how Prowl ended up being persuaded into singing karaoke in the first place, and how overcharged he was. 😀 Either a torch song that gives away waaay too much about how he feels (especially towards Chromedome) – I’m thinking “With Every Breath I Take” from City of Angels, or, more wistfully, Tom McRae’s “Vampire Heart” – or something startlingly filthy to make everyone else in the room deliberately uncomfortable. With dancing. And optic contact.
