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 his "video-game-inspired" characters and asked me to choose the ones I will make for him.
Maybe later I'll make fanart of his other characters?

🤨 Oh, one other thing...Is it pronounced "GAL-a-ga" or "Ga-LAH-ga"?

Well, however it's pronounced, it belongs to Namco.
