Monster Alliance GO Theme features cute graphics, funny but relatively few icons, and smooth screen transitions and performance. Because of its cartoonish graphics, though, it's more appealing for children and teens rather than adults. The only annoying thing about it is that although it's labeled as free in Google Play, you actually have to pay to use it with money or Goldjar credit.
Monster Alliance GO Theme installs without any hassle if you already run GO LauncherEX and then presents you with a brightly-colored interface. In spite of its name, this theme has nothing monstrous about it. The blue and green background looks cute, as do the 24 finely-crafted colorful icons, which depict various little monsters, one more adorable than the other. Unlike other GO LauncherEX themes, this one doesn't have any special live wallpapers or animations, but that means a lower impact on your battery life. Screen transitions, app management, and switching between apps are all smooth and effortless with this theme.
Overall, Monster Alliance GO Theme makes your home screen and icons more fun, without affecting your device's performance, like other themes do. If you like cute monsters and bright colors, and are willing to pay for a theme that's listed as free, then you should give this well-designed theme a go. Keep in mind, though, that because of its cartoon-like graphics it may not be particularly appealing for people who use their smartphones or tablets for work.
