The ATD (Anti-Tank Dragon) is an unmanned anti tank vehicle that appears in Xionic Madness 1, and is quickly destroyed by Xero, using The Ripper, first by cutting of 2 of its 4 legs, then switching to his AT mode (The HUD changes to pay homage to Shadow of the Colossus), before climbing atop it, and stabbing it in its weakest point. From there on out, it is only ever mentioned again once, by 2 soldiers at the begining of Xionic Madness 1.5, and from that point on is never heard of again.
