(Jesus Christ here we go, this fuckin' guy.)

Grenades was BLEU's janitor being being enlisted onto their team. They first watched him talk to his equipment with taped drawn paper faces on them, and he did so like a drill sergeant. This was a funny pass time to BLEU until they saw him express some genuine combat skills. 

He's an absolute crazed maniac with an affinity for explosives, so Cyborg engineered a mass produced line of grenades for him... take a guess as to how he got his name then.

During a mission he was sent on from Cyborg, he wandered into the forest oasis of the badlands and came across a large tomb with a brass statue of a man that looked just like him. He saluted promptly to the statue, for it was already showing that gesture. This expression of respect opened up a well crafted compartment on the side of the tomb. He was presented with three objects: A large rocket launcher, a pair of metal soles, and a bloodstained tactical shovel. Above it read:

"Get into a war, and win valiantly with my arms! If you already are in war, use these to kick their asses! 

-Jane Doe"

Grenades speaks of this man like a god, and has these weapons in his locker ever since.

"AAAGGHHHHHH!!!"
