The Blue Dragon community within planet earth was an extremely cautious one.
Firstly, they hid their only entrance deep within the Pacific Ocean, as far away from pesky human eyes as physically possible, protected by kilometers of water.
Then, they put in place an advanced stealth force field as their second layer of defense, mostly to avoid their loud roars and mechanical parts from being detected by sonars and sensors when they were out of their paradise for the occasional trip around the ocean.
Then there was the massive killing room which could easily massacre millions of human beings or hundreds of thousands of their mechas.
And finally, their hidden entrance in the form of a portal.
All of these measures pointed to one very clear fact.
The Blue Dragons were in hiding, and they did not want to get involved with the rest of the world.
