Beast Boy knew that from day one, once the green skin came, that having anything close to a normal name was impossible. He understood that his team often resorted to nicknames, some very questionable, while others made a single appearance than faded back. Of course, with the ones he came out he should have expected to have several thrown back in return.
Cyborg was constantly throwing them out there. There was the playful one of moss head, but the one that stuck, no matter what the circumstance, was grass stain. His metal friend took to shortening his name, too. No, he did that with everyone, except Raven since Beast Boy was the only one who got to do that, but with Cy he actually managed to take his name and turn it into one or two letters. BB or B was so natural to respond to now, it was almost like having an actual name like Sam or Luke.
Starfire didn't mind calling him his actual superhero name, but since she had gone out with Jinx and Raven, the alien had taken to calling him pixie. For whatever reason, and no matter how hard he tried to figure it out Star wouldn't budge. He knew he was royally screwed when Jinx came over, and in all seriousness, she and the red head had screamed that name so loud that he was sure that people on the main land could here it. She finally did explain it to him; she read a fairy tale book, saw woodland creatures with green skin, thought of him and that was that.
Robin only has one-one-nickname and he bites the head off anyone else who uses it. Actually the rest of the team didn't find out about it till a few months after Robin thought of it. They were stuck on an overnight mission, in the middle of some snowed in warehouse, and he couldn't shift at the time due to 'other reasons' that Robin wouldn't go into. He was cold; Robin was being a big pain in the butt about mission crap and whatnot, so he had started moving. Old training moves or simply tapping his fingers on his leg helped warm him up a bit, but clearly Robin had different ideas. Bunny came out and the only thing Beast Boy could do when Robin said was blink…and then remain as still as possible till they got back home.
Raven seemed to find ways of calling him different names. There were many, oh boy were there lots, and the best way for the rest of the titans to see how many she could come up with was to get her yelling at their resident shifter. Idiot seemed to be a constant term, always on the tip of Raven's tongue, but over the years it's become more of an endearment than an actual insult. Other than that she usually calls him by his name. But after the team met the Doom Patrol (that night back the team picked his brain on everything about them), Raven seemed to find great pleasure on calling him by his actual name. Never in public, and sometimes not even in front of the team. During those first few months with having the girl know this was absolute hell; Beast Boy really didn't think he could ever hate the name Garfield so much. But then, during one night at supper, Raven made her jab.
Not the usual one with Garfield, but something…nicer. If that was even possible concerning Raven and himself. Gar hadn't sounded that nice in years…the fact that Raven kicked the butt of whoever else tried to call him that was heartwarming, too.
