In titling a previous post, I refered obliquely to Tim Drake's (Robin's) on-going attempts to reproduce the cloning experiment that created Connor Kent (Superboy).
Today, however, it occurred to me that it's quite possible -- even likely -- that Tim is not trying to create a Superboy clone.
Connor was Tim's best friend, true enough. But Superboy was created by Lex Luthor to be a weapon, and he was. Through some vague sci-fi "pre-programming", Lex was able to control Superboy to attack his foes. Superboy broke Tim's arm, in fact. One remembers things like that.
Furthermore, while Superboy Prime was a million times more powerful than Superboy, it was still a Superboy whom Robin watched kill scores of editorially unnecessary Titans, ensuring the everlasting fame of the Rolling Head of Pantha. One remembers things like that, too.
In the year before OYL, Superman, the logical person to stop a Superboy run amok, has been powerless and out of commission. Meanwhile, the Brotherhood of Evil has been stealing cloning technology and personnel, ostensibly to make a new body for the Brain, but with who know what other goal in mind.
I don't think Robin is to trying recreate Superboy.
I think he's trying to make sure no one else can.
