Bat-De-Icer ???

I'm guessing:

Folgers Coffee.

The power of friendship.

Rudolph's nose.

A magical wish granted by a mermaid.

A time-traveling Mr_JTR.

That's actually the closest guess yet.

A hug from that girl in Santa Clause 3?
Remember her hugs even deiced Jack Frost...so that HAS to be the answer.

I'm guessing Bruce made some kind of machine that cured him.

Nope, twasn't that.

He got him to drink some Bat-Brandy ???

It warmed the cockals of his heart. Maybe his sub-cockals. Maybe even his colon. We don't know.

It's been three days and no one has even come really close, so I'll call this one unanswered.

In his first appearance, Mr. Zero was temporarily* cured of his necessity for extreme cold by a blast of steam.

No, really.

Anyone who wants it can ask a question.

*Temporarily until his character, now called Mr. Freeze, became popular on the Batman TV show and was revived in the comics.

You'd think a blast of steam would've killed him instead of cure him. Ah, well.
I'm passing up the chance here to ask a new question. Letting someone else have a go.

Goody! Here is an easy one. At first Ambush Bug had a limit to his power. Now he can teleport anywhere at anytime. In the begining what did he have to do to teleport to a certain area?

He needed the help of robot bugs, whereas later, he could teleport himself under his own power ???

Told you it was easy Mr. JTR is correct.

Eh, here's an easy one.

Name three woman who've been romantically involved with Clark Kent/Superman, who had the initials "L.L.".
