Dragonshock got his name from failing to use the basic dragon shout from skyrim. His new dragon shock ability does absolutely nothing besides shaking the ground in a foot radius around him. This is good for keeping snakes and fan boys of his justin bieber type music away.
"Combustable Lemons." the voice whispered, lowering a bowl of lemons down in front of John. He stared in awe, plucking a lemon from the pile. However, the voice didn't like this, so it shoved all the combustable lemons into John's young booty hole. ( ͡° ͜ʖ ͡°)
From that day forward, Johnson was a man, and went by his full name. The expansion of his bum from the lemons was rly big, so he came to be called "Cave Booty," and eventually became Cave Johnson. The End.
P.S. his booty was burned from the lemons combusting in there, but his flesh woulds were soothed by the lemon juice, and he worships the loving Lemon God to this day, hoping one day he will come back to recreate the experience.
(Hah, you thought his name would be Cave because he explores caves. That'd be boring)
