Supergirl #63

Batgirl comes to Supergirl's rescue as she is not faring too well in battle against her Bizarro self. Meanwhile, Buzz and Two-Face have been infected by the Joker's laughing venom and cause havoc by throwing their illegally-earnt money away in the streets. Batgirl takes out Two-Face, Supergirl takes on her other self, who has the flame vision she no longer has, and then reconciles with Buzz, who is weeping due to the odd effects of the Joker juice on his system.
