The Ultra-XI series was meant to be a replacement for the Ultra VI series, but became a massive failure after they were first put into combat. They did see combat during Glockenspiel's attack on Earth. Where there unique Ice-Proof shields became very helpful.
Role in the GameEdit
The first one encountered by the Player's monster acts as an ally. It is very different than all other, due to it being the Only known Ultra-XI given an Approval by RoyalGaiaGuild's standards. It code number was, 343. The second time they are encountered is during a battle between the RGG forces and a Giant Ant hive against Glockenspiel's ice legion. The Player's monster does not directly participate in the battle, but does free the Giant ant soldiers captured by the Ice Legion.
