Oohhhh goodie, haven't seen Zoids: Chaotic Century in years.
Sadly, the group of bishounen Gundam pilots and their Gundams are screwed in this match. While the Gundams have the advantage of flight and speed in this match, they won't have any means of offing the Deathsaurer thanks to its thick armor and powerful energy shields which were capable of tanking multiple charged-particle cannon blasts from the Geno Breaker and even the Gravity Cannon of the Ultrasaurus that was capable of generating a gravity field that could level an entire city. The Death Saurer, in storyline, was single-handedly responsible for wiping out nearly the entire ancient Zoidian civilization and is capable of firing bombarded particle blasts capable of leveling multiple cities and traveling far distances in a matter of seconds. Any one of those blasts would be more than enough to destroy the Gundams.
Skip to 0:40. It took out the empty space colony that was going to be dropped on Earth as part of the original Operation Meteor. Dekim said it was an empty colony I believe but it looks more like some kind of massive base.
