Mister Freeze?

I was watching the Batman: Subzero movie this weeken and it occured to me that it really ought to be Dr. Freeze, oughtn't it? He has a doctorate, they say so right in the movie when they call him "Doctor Victor Fries". You'd think, having gone to the trouble to get a doctorate, he'd insist on his proper title, but no.

I imagine there's an argument that he feels Victor Fries is dead, and so the title doesn't pass on to Mr. Freeze, but I can't really buy that given his actions (at least in the majority of his portrayals) are motivated by things from his life as Victor (namely, his Popsicle Wife*). His old life does still have a hold on him, so why not carry over his title, especially since he still utilizes the expertise he gained during the processing of earning the degree.

Perhaps it relates to the fact that much of what he's done is related to Nora, and since that's a personal matter, one of the heart, his education, his former professional life is irrelevant, and since being a doctor was part of that, he left that aspect behind.

I suppose they dealt with it in the version they created for The Batman series, since that Mr. Freeze was just a thief trying to escape from Batman, not a cryogenics expert. That was an interesting choice, because it shifted the guilt and sympathy. With Batman: The Animated Series, Freeze had been a man in love, destroyed by people more interested in the bottom line, and we were supposed to feel at least a little bad for him, even if he was fairly indifferent to the damage he inflicted on people who had nothing to do with his loss. In the newer series, that's not really the case. He was stealing**, he tried to escape Batman, he accidentally fell into a cryo tube, and now he has ice powers, which he immediately sets to use stealing for his enjoyment (as opposed to stealing to gather equipment to care for a loved one). He's much more of an out and out villain, a Norman Osborn-Green Goblin, rather than a Harry Osborn-Green Goblin. Yet, Batman feels guilt over this turn of events, since he couldn't save Fries from falling into the tube, or winding up like he did. Whereas in the earlier version, Batman is just the outsider vigilante that has to clean up the mess, now he's played an active role in the creation of a much greater danger than an ordinary thief. It's a different dynamic, which is a nice touch.

Supposedly (according to Wikipedia, anyway) in his Silver Age origin, Freeze (or Mr. Zero) took a shot at Bats with the freeze gun, only to hit Nora's capsule and shatter it when the Caped Crusader dodged. I wonder if Batman spent anytime dwelling on that, wondering if he could avoided the shot in a different way.

* Except she isn't a popsicle anymore, as of the last story arc in Batgirl. She's back, with power over the dead. I wonder whose idea that was, and if it survived the reshuffling of things that's gone on since the end of Infinite Crisis. Personally, I would have preferred the drop in the Lazarus Pit either restores her back to a healthy, normal person, or it doesn't take and she's finally dead. "Superpowered wacko" just seemed an odd route to go.

** I guess B:TAS Victor was stealing too, since he was using company funds and equipment for a personal project, though as successful as his cryo tube had been on Nora, the company certainly ought to have been able to make some serious bank with the patents, and they could have left Victor to care for his wife.
