Dedicated to bringing you fun
I'll tell you what I did (yes I went to the Ironfest at Lithgow but that's another story), I flagged the intention to write more - or point and shoot more - comic book stuff (for those interested in that sort of thing), when I was pointing to something that I had saved in draft format but which would then post before the entry that announced it. Confused? The illusion of a flux in the timestream might be a good segue to that very comic discussion. And if it's a time based protagonist you want then one can't go past Hourman. Or can't they?
To me, calling yourself Hourman when that's how long your vitamin supplement that gives you your powers lasts, is akin to starting out your caped crimefighting career as Sensitive Groin Region Man.
No superhero whose raison d'etre is based on power limitation is all that popular. Ultraboy is not a name you hear often.
Whereas wielding a magic ring or being able to leap tall buildings is a superpower that can help identify the character and make them interesting, The Hourman and his ilk usually possess vast power but in a limited fashion and that only extends the 'variation on Superman' perception.
Whether Tyler is the first drug-taking superhero depends on the properties you ascribe to Miraclo; does its boosting qualities make it like ginseng or is the effect more like a speed user whose wits are momentarily sharpened? The temptation to use some outside agent as the source of the protagonist's prowess is irresistible and not even the squeaky clean British weeklies were free of herbally-enhanced characters. And it was a couple of decades before the famous Denny O'Neil/Neal Adams social relevance would make Green Arrow's sidekick Speedy a heroin addict. A couple more decades before a character's book would be advertised on a double-page spread as "This is Sludge" and "This is Sludge on drugs"
