I'm sorry, but this chapter is too short for my tastes. I'm going to have to restrict you from posting further updates until this one is made longer.
The biggest concern I'm having is your attention to detail, and by that, I mean there is none. There's no description, and you're telling us the tale. Have you ever heard of showing vs telling? Well, instead of telling us what happens in the story, show us. Here's a nice little article I recently read on the subject, and I think it's pretty helpful:

There are a few mistakes in your writing as well.
if they disobeyed, he'd attack them with moves that the colony thought was not possible.
Remember to start off each sentence with a capital.
He Singed them with a DragonBreath, and then gruesomely stabbed them to death with its sharp blade.
A couple things here, I'm not sure why you decided to capitalize "Singed". The other thing is when you used "its". You've already identified the Grovyle as male, so I'm not sure why you decided to go with the gender-less article here.
it was safe for 6 years....
Again, with the capital letter at the beginning of the sentence.
I'm not going to quote all of the mistakes, but you have a lot of random capital letters that shouldn't be there. I would recommend giving this a thorough read-through and smoothing those wrinkles out.
Like I said before, I want you to work on this some more before you continue. It might be a lot of work, but writing isn't easy, and I want some real effort put into these fics. If you need any help, I'm always willing to lend a hand. Good luck.
