Liger Zero Panzer Papercraft
This is Liger Zero Panzer from the anime Zoids Zero that was shown on tv back in 2001.
The third CAS for the Liger Zero (in both the anime and models), the CP-21 Panzer is specifically designed to be a heavy-artillery Zoid.
It has a great number of missiles, as well as two powerful “Hybrid Cannons”, and is wrapped in a thick armor that offers much more protection than the basic armor.
However, this comes at a cost, and the Zoid is not as agile as it would if it were to mount the other CAS units.
