This Glad Hander is one tough cookie. Often schmoozing and scheming with her bro Ignatz. While being very good at her job as a Saleswoman, she's often reviled by her fellow Sellbots. Isolde's petty and immature personality makes it hard for her to work with other Cogs due to how she sabotages them over a petty dispute. Sometimes her tactics are too competitive, perhaps underhanded. She forgets the effort to take over Toontown and turning it into a corporate paradise is a team effort.

Isolde is a gal with no chill and enjoys teasing and annoying Toons, usually with phony contracts and making fun of their appearance, sometimes... She doesn't really dislike Toons; she just hates anyone getting too close to her crush Glen. Doesn't help that she's prone to envy and often it gets the best of her. She won't ever admit it, but she does wonder if she's defective or not. Like any other Cog, she aims to get to the top of the corporate ladder but she knows deep down that her emotional immaturity gets in the way of this. Unfortunately, she doesn't know what to do about it. 

But don't be fooled, she's not the kind to sit around a mope about her woes. At her best, she has an iron will. Once she's set on something, it'll be hard to talk her out of it. It's that determination and decisiveness that has gotten her far in her life as a Cog. This immovable willpower paired with a desire to prove other wrong make her a force to be reckoned with. If she wants something, she'll do everything in her power to get it.
