He's not dead. He's resting.
In "Superboy" #61 (April 1999) the troubled and occasionally tiresome teen bounces around Hypertime in a hi-tech/lo-fashion atomic-powered jacket. Superboy wears it with the collar up. Of course. Because he's kind of a twerp. I'm sure he'd roll up the sleeves, too, if they hadn't been reinforced with circuitry and isotopes and whatnot.
He runs into a bunch of other Superboys, some of whom are shown on the cover.
At center left, there's the Clark Kent Superboy, of course. He's the guy in the inoffensively boring -- ow! Quit pelting me with your HeroClix, fanboys! -- okay, make that "classic" costume. On the bottom is Superboy-as-Robin. And I think it's funny that the only costume elements I hate are the ones taken from the Kesel Superboy design. All those lame-ass straps, for instance. I do like this color scheme better than the one on the actual Robin costume. Huh. Between the Clark Kent and Robin Superboys is the DC One Million Superboy, all OMAC'd out. Now, I understand what Kirby was going for with that ridiculous hairdo but it still looks dumb. Doesn't look any better on Superboy, either. Nice shoulderpads, though. You know me; I loves me some good shoulderpads. (I bet his don't have any storage capacity for snacks, though. Me, ten points, Superboy, zero!) The blonde teen queen to the southeast of Superboy Proper is... wait for it!... Supergrrrl. Cue musical stinger, played on a trombone. Wah-wah-wah-WAAHHHH! Jesus. As if this book wasn't dated enough. One word of advice, "Supergrrrl": don't take hairstyling advice from Rachel Summers. I'm just sayin.' All armored up behind Clark Kent Superboy and the Kamandi-esque, Tarzan-ish Superboy is squire Superboy, also seen below next to Cowboy Superboy. Or "Supercowboy." Or whatever. I dunno.
Say...! Sir Kal is hot! Somebody needs to teach him the proper way to tie a tie, though. (Seriously, what the hell is up with that? Does he work at Chippendales?) Cowpoke Superboy is more nattily dressed than squire Superboy -- although he's pushing it a little with the fringed boots.
And lest we forget, there's the villainous Superboy! No, not the stammering whiner from "Infinite Crisis." The other one.
Oh, he's so terrifying, so unmistakably evil, I -- I -- heh... BWAH HAH HAH HAH!!! WOO! *wipes away tears* Oookay, "Black Zero." Here's the deal. The breastplate thing, based on Mike Mignola's designs for battlesuits from that old miniseries he did with John Byrne? That's terrific. Love it. Combining it with a black bodysuit? Classic. Looks great. The scribbly Byrne Doodles, meant to evoke Byrne's costume designs for Jor-El and his kin? Not good. They never were good. They're just another example of Byrne being lazy, like when he decided Wonder Woman's tights only needed two stars on 'em instead of dozens. Also? They kinda look like pubes. So thumbs down. The sunglasses? No. In fact, make that hell no. I know Superboy used to wear 'em a lot, but big effin' deal. They're a trendy, casual accessory and they take away from your aura of menace; they don't add to it. You don't see Darkseid strolling around in a Panama hat or Doctor Doom with one of those big rapper-style diamond necklaces that spells out his name. The only villain I can think of offhand who wears sunglasses as part of his regular costume is Doctor Octopus, and he's a fat guy with a bad haircut. If I looked like that I'd wear sunglasses, too, STORM BOY. And then there's the soul patch. Those things are always dicey. And to be frank, the rest of your look isn't hep enough to pull that thing off. Not with that Fantastic Sam's haircut, it ain't. Shave your head, ditch the sunglasses, and get back to me.
Well, that's a weird coincidence, Superboy. I was also going to suggest you "lose the jacket."
But not because it was explosive.
