Have you checked out the official website for Spore Hero?  MaxisCactus posted a note over at the Sporums that the website has updated with a few new pieces of content:

In Spore Hero for Wii, and Spore Hero Arena for Nintendo DS, you can create your own hero and fight to save the galaxy.

At sporehero.com, take down creatures in Meejee’s Target Practice, grab a Hero widget, download cool Spore stuff, and see the latest videos!
