Australian actor Chris Hemsworth is the cocky, self-assured Thor, whom his father Odin (Anthony Hopkins) has chosen to replace him when he retires -- something Thor’s weaker, more introvert brother Loki (Tom Hiddleston) isn’t very pleased with. The ambivalent Loki has a sinister plan and he arranges so that the old enemies of the Norse gods; the Frost Giants, can attack Asgard -- which they do just when Thor is about to become the new king.

Like all our Superheroes, Sniffer Dog is always on the prowl for those with extra super sensory talents to help in the fight against, well everything banal in this world. And so he has welcomed, after much study and investigation, a new canine superhero to our list. With final approval from the Controller, especially after noting his bargain price, he will work alongise Sniffer and the other heroes.

Arrowette is one of those cases of just taking an idea way too far.
Of course Batman and Superman have that cornered, but here, Green Arrow actually gets to be stretched pretty thin.
I mean first there is The Green Arrow.
Then Speedy.
Okay, not bad, he's not called Arrow Boy right?
Then the DC writers went a little nuts with the Arrowcar, Arrowplane (actually that is one of my favorite names), the Arrowcave and the Arrow-signal.
So it's only natural a female character would appear.
And since I guess Arrow Girl was taken, her name was Arrowette.
