Which box is this in, the left or the right? If it's the left, that's just how it shows up in the editing. If it's the right, then if you're just posting a google image, then I believe that when you click "From the web" it just posts the url; you'd likely have better results downloading and re-uploading the image.
As for that kind of battle, as Antroz said, we'll likely be getting that in the Civil War arc, which works far better in this case than Makuta having an army because of the tragedy of the good guys battling one another. Having a good versus evil army certainly isn't bad per se, particularly when done well, but it's been done to death before, particularly in LEGO, and Makuta's manipulation and a more personal, psychological (admittedly I'm very much guessing here given the lack of details at the moment) conflict will have more meaning than an army battle I feel.
And at the moment, I don't feel that there's a way to make an army not feel contrived other than maybe the cultists being enslaved, but even then, I feel that they wouldn't be a main conflict, only a distraction for Makuta's purposes.
