A set of ideas I had for a Koopa gang that I wanted to draw. Careful since they tend to play for keeps. They are evil... kind of...

Isaac Koopa- Age: 15- Scientist determined with discovering the secrets to digestion. He plans to create a specialized army of potentially unbeatable post-digested minions who cannot be defeated by force or consumption alone. Always looks for ways to improve on his only somewhat successful experiment Gloopshi. Lives in a small fortress with his older sister Miranda and adopted little sister Mi. He is handy with advanced technology which is handy since his older sister Miranda is the main reason why they don't have minions in general.

Gloopshi- Age: basically stopped at 14- Isaac's first (and only) successful post digestion experiment. Given a new slimy and somewhat stable form and a new name Gloopshi is always looking forward to his next meal. Not very smart to begin with he was easily tricked into being Isaac's meal/test subject. His new form has caused his original colors to become bright and washed out. Isaac gave him new rubber shoes and a replacement saddle. When Gloopshi eats enough he transforms into his Yoob-like/Mega form. He moves much slower and his appetite is just a big, but his size is only twice his original. He is able to absorb prey and liquefy his body to squeeze through tight places.

Miranda Koopa- Age: 16- The older sister of Isaac and Mi. She is very greedy and usually makes a meal out of everyone. Basically she is the reason why they don't have any real minions that aren't robotic since most of the staff has become a permanent part of her. He has expensive tastes since she also eats treasure. She's seductive and has a few special tricks up her shell. She kidnapped Mi from a homeless shelter and turned her into a Koopa. Its unknown why she did it.

Mi Koopa - Age: 7- A homeless human turned Koopa by her older sister Miranda. She is generally nervous most of the time and Miranda tends to boss her around. She like frogs and tends to where a frog hood and shoes. She can also turn into a frog to catch prey from afar. She feels bad about eating others, but she's starting to get used to it. Gloopshi usually hangs out with her to cheer her up (and eat her) most of the time.
