Overall- One of the problems about not growing up as a fan of DC comics is that there are still a few obscure characters that I really have no idea about... I can only recall reading one thing involving Kobra, and that was the "Flash" comic books where Kobra wanted to destroy Keystone City, or some such super-villain shenanigans. Flash, Max Mercury, JSA Flash, Jesse Quick(Liberty Belle)and Impulse wound up defeating Kobra that day.
Since then, I can't say I recall reading anything about Kobra. For the most part, this comic wanted to set-up a new Kobra(the twin brother of the original Kobra(?))as a sneaky villain who would strike through terrorist activities at the heroes of the DCU, before disappearing back into the shadows. I like the premise, but there is no way I can even begin to explain the convoluted story about the two Kobra's and Kali Yuga(what ever that is). What I took from this comic book was that the new Kobra won't be working with a large group of henchmen like the old Kobra did, but will be operating almost solo, along with a few fanatics who are willing to take their own lives when told to.
Overall, like I said, I really don't know much about the earlier version(s) of Kobra and this issue did little to explain who/what the old Kobra was all about. Ignoring the stuff I didn't understand though, this was an OK story, deserving of a score of 5 1/2 out of 10. I'll probably do some research into the earlier Kobra now, in order to gain a better understanding of who/what he was.
