These three characters belong to "SporeVideos3" of DeviantArt and were inspired by the video game Galaga.
The one in the middle is Queen Galaga herself, and she's accompanied by her best warriors Goei (left) and Zako.
He gave me a selection of characters and asked me to choose which ones I will make for him.
Maybe later I'll make some fan art of his other characters?

?(•?_•??) Oh, one other thing...Is it pronounced "GAL-a-ga" or "Ga-LAH-ga"?

However it's pronounced, it belongs to Namco.
