I knew I should have mention that. SD stands for Super Deformed. The character is out of proportions, but on purpose. Chibi is the same as SD. It's often used in anime for comic effect. Heh, there is a gundam series called SD Gundam: G-Generation that had all the gundams from all the other series, but they were all super deformed and had HUGE heads, but little bodies. I don't have much information on the series though. But I do have an AMV of it (anime music video), and it's all computer generated. Looks pretty cool. It basically shows computer generated versions of really famous gundam battles from the different series, like Wing Zero vs Epyon, the final fight of 08th MS Team, the first fight of Char vs Amuro (Red Zaku vs. the Gundam). Pretty sweet looking.
