@DivaDoodle Klaus's traits are Brave, Disciplined, Evil, Flirty and Great Kisser. His LTW is Master Romancer.
I have occasionally had a sim that will autonomously brawl with others. I clearly remember one that I banned from my game for years because she was constantly rolling around on the ground with one other member of the household. Then I added her to the household for my Isla Paradiso Bunch videos and she behaved her self throughout the series.
This is a screen shot I got of the final fight she picked. I saw her jump onto her housemate who was about to walk down the spiral staircase. The housemate is the one with the blond bun. Josephine was still a blue genie at the time.
Josephine was kept out of all games for years until I finally added her to the Isla Paradiso Bunch household and gave her a makeover.

I don't remember all of Josephine's traits. She is a coward and often fainted when the ghost of Mia Azul came out to haunt the house. Mia Azul died in their house at a bachelorette party that went on unsupervised for too long.
Here she is slapping one of her household members, Diana. This pic is from the Isla Paradiso Bunch series. The sim working on making an elixir is Judy, my first ever witch.

I have two series of videos on the Isla Paradiso Bunch in my channel. There are a few people hoping I do a third but I want to get a few other series completed first. In the first series they are trying to get me badges from the Island Paradise Expansion and in the second series they do walkthroughs of all of the tombs in the World Adventures tombs. If I do a third series it will be family life. The household expanded greatly during their adventures and I used Porter mod to move them to a new home world (Dragon Valley) and then started breaking them up into family groups. I do really want to continue playing them. The first family group I broke off has Judy (the witch) as head of the household. Her household is so large that it is already overstuffed. That is where I first started giving major makeovers to my Imaginary Friends made real. Although Judy has no life partner and has never been pregnant she has numerous children she's collected during her adventures including a mermaid (clone of Triton King) and two plant sims (Judy picked in Isla Paradiso) and a plant sim Judy planted when the plant sims first came into the game. And she cloned herself in that same game from years ago. And there is all of their imaginary friends made real. I knew I was forgetting someone, Judy also cloned one of the Sims from France and that's how she got Donna Dutiel who is currently a child.
I do like colourful characters in my games. I spent years playing with households of 8 unrelated sims. I just made a new group of 8 sims in Create a Household whenever I wanted a new game. I would put them in a big house with lots of stuff in it and watch them. I usually kept them home but some went out to work and sometimes they'd go somewhere to take a class. Klaus and Josephine were made for this type of household. Most of the 'old' sims I have as townies are from these groups of 8 unrelated sims. I'd mostly just direct them towards skills but left everything else up to them. I found it hilarious to see what they got up to sometimes.
EDIT: Josephine doesn't have the evil trait so that isn't what made her so combative. The only one in Isla Paradiso series with the evil trait is Meryl and she never gets into fights.

She is constantly autonomously going into town to try to find out if various townies are rich and if they are she tries to seduce them as she wants to see the ghost of her wealthy spouse. So far she's had no luck.
