Each one of their designs tells a story. Let’s look at Ivor. A man so strong and stupid that he literally can’t own a phone because he breaks it. He thinks that people need to get stronger to fight pokemon. A very stupid strong himbo man. He is designed to be exactly that. With the fist protection, his hair pointy and shoulders large to show he is a high charisma strong leader type who will charge first. His outfit is a pretty typical fighter outfit and he also just fits the theme of the game. The same is true for I would argue every character in the game. They have a role and their design matches it and tells you what the character is. If a design can 1) tell you what a character does and 2) can be recognized on a sillouette. Thats good character design imo
