Say what you will about RAID, the character designs are some of the best I've ever seen.
These mobile games can have really good character design or story. I fondly remember Heroes of Incredible Tales for one of its characters, and I keep fond memories of Overhit for how different every world felt. Even if they were both incredibly lame. I always find it a bit depressing, because you can tell that despite how bad the games are, the devs actually try. It's not a complete shovelware.
