Close to Strange, hmmm.....
Dr. Little-Bit Odd?

Or on the other side, Dr. Bat-#### Nuts?

Actually Dr. Little-Bit Odd is not correct and neither is Dr. Bat####Nuts !

I don't remember who actually killed him, but I'll guess the Ancient One.

Actually, Dr Strange killed the Ancient One.

No the Ancient One is incorrect. Don't know any other hints to give, will repeat it was someone very close to Doc Strange.

Was it "Strange", the Doc's doppelgänger ???

No, I don't believe so...at least from what I recall he wasn't referred to as that.

This came out of a short run, not too many years back.

The person was killed by the Ultimate Dormammu.

OH. The Ultimate version of Dormammu.

The Dormammu of the Ultimate U killed Dr Strange or Dr Strange's son, depending on how you look at it.
I can't remember if the son had been an actual Doctor or not.

Yep, sorry, should have said about Ultimates sooner, was wondering why you...Mr JTR had not gotten it yet. Yes actually it was Stephan Strange Jr. who was slain.

Once again the floor is all yours!

"Ivan Kronov" was the real name of what supervillian ???

That would be....Electro!

And then he got his bill from the electric company and decided to quit, then go green and become "Solaro".
The Electric Company once made Spider-Man work for them to work off his own electric bill.
Yes, Electro is indeed his name-o.

The thread is all yours, Mikesim.

God, its scary how much obscure crap is in my head...

Ok, here we go:

Spider-Man and the Beast once teamed up against a certain mechanically inclined villain...who was that villain?

Was it Mike Rutherford ???
Or Professor Power ???
Or The Griffin ???
Or Killer Shrike ???
Or Modular Man ???

Hank and Pete have teamed-up quite often, especially in the 70's.
I just can't remember all of the foes they faced together.
But I wouldn't blame them for smacking Mike Rutherford around.

Actually, I was thinking of Modular Man...but if I recall, wasn't Killer Shrike in that issue of Marvel Team-Up, too? Regardless, Mr_JTR is the man!

Batter up...
