Onceler is a skinny and tall man, overtaken by his own greed and need to make everything bigger and better with little to no regard for anything else around him. He’s an intimidating, and slightly cruel individual. He can be charming if flattered enough, and since he used to be a normal easy-going character he still has a sense of humor to him. He’s self absorbed and chooses to be blind to all the environmental damage he caused. He’s very dorky and plays guitar.
