Cave Bigrat
Bigrat's Sprite.

Cave Bigrat is a secondary character of Mega Man X: Unit 49. He is the strong leader of the rat-only thief group called The Rats.


Just like his younger brothers, Cave has the general appearance of a humanoid rat, although he is much bigger than any of them. His body has a lot of claw marks with red lights inside and also a thick tail at the rear.


Cave's actions are very cautious, as he fears being responsible for the death of his brothers in avoidable battles against stronger enemies. He is ambitious for the money earned by selling their stolen goods, but will not risk his life to make a sucessful trade.

He does the best to remind his brothers to follow their code, as it was written by himself and reflects his own life philosophy: run for you life, so you can live to attack the enemy off-guard another day.


Before the Great Neo Maverick WarEdit

Cave Bigrat became the leader of his family at some point before the events of the comic, and made raids along with his brothers to steal weapons, technology or information and sell for another criminals. They started to make hideouts through the world, normally in the underground. He teaches his brothers the doctrine of avoiding combat at any cost and always runs to survive and fight another day when he is in advantage.

The Neo Maverick Army took over the Iberian Castle and bought a package coming directly from The Dealer, an enigmatic and famous merchant, not so long after the news reached Cave's ears and he prepared an ambush with his brothers. They succeeded and stole the Jammers, installing them in central computers of the castle sewers without knowing the extent of their powers.

Bigrat announced he was with Dealer's Jammers and a buyer soon got buyers interested.

Cat and MiceEdit

On June 22nd, Cave is discussing with his brother Sewer Jailrat about abandoning the hideout since the enemies were probably too close and the buyer was taking too long to come, when the Maverick Hunters Mega Man X and Zero appear just when he said about the absurd possibility of them showing up.

Cave, Ivory and Ebony manage to get out of the place without engaging combat, but when they are about to escape they realize that Sewer Jailrat had disappeared.
