Win some, lose some
I like them as a team, and now they have powers. Sort of.
On the minus side, the former most wanted are here merely served up as an entrée for Batman. They go down so easy that you can practically see Bats yawning. And they aren't all that impressive anyway.
Dragonfly has the ability to summon some white misty stuff from her arm. What this does, we never find out because Bats takes her out in two panels. And it's only that long because he pauses to give them a quick "sux 2 B U" speech.
Tiger Moth appears to have the power to shoot people.
With a gun.
This leaves only Silken Spider, who gets a nice visual, but then it turns out all she can do is some variation on the pheromone shtick that Poison Ivy worked to death years ago.
I'm left wondering quite what the point was. Why dust off an obscure concept from 1966 and give it a makeover, only to throw it away in seven pages?
Will we see them again? And if we do, will they ever be anything more than cannon fodder?
Update: Yes. We see them again in Nightwing #138. They are once again defeated as soon as they appear. Congratulations, girls. You've become a running gag.
The odd thing here is that they are referred to as has-beens, even though they've never been seen before in current continuity. This suggests that they were at least competent once. Shame we don't get to see any hint of that.
