Invincible: Every Main Character Ranked Worst To Best

You really get the full package with Monster Girl, as she ticks all the boxes needed to be an exciting member of the team. She is funny, she's got some great moments in the narrative, and she has the awesome power of turning into a hulking monster. But, most of all, she has a genuinely inventive weakness that gives her a fresh flair of uniqueness.

At first, this character came across like a little girl with a mouth far exceeding how her parents would want her talking. But, you soon learn that she's actually 25 but ages in reverse every time she uses her powers. This is such a fascinating concept, as it delivers on a sense of personal sacrifice that all superheroes have, but manifests it physically.

In addition to her excellent character concept, she's also an absolute delight, as her cavalier attitude and the complications that come from her appearance are a constant source of either comedy or drama. This was particularly evident in her relationship with Robot, which saw the pair form an unlikely bond.

She's a great part of the show - even if her flirtations with the team do make us a little uncomfortable - and only falls behind because she didn't get quite as much time in the spotlight.
