So as it says in the title I used to play/ Gm pathfinder all the time. As of now though I have been struggling with personal issues I feel have drained my creativity.
So I feel like I need some help with some substance to help me with my general setting/ plot.

The setting I am working with is within the Pathfinder/Starfinder universe but is placed within a fringe system.

The system is Known as the Orgidus system.
It is a Red Giant system with a star known as Sultan Zsolt.
Its a system with a few desolate planets and one that seems to be habitable. But that really wont matter at the moment.

The starting locale for my players will be a mining city/ station floating within the system's large asteroid belt. Newly discovered after the gap.
Named Arkwell after the family of dwarves that discovered the abandoned Archeo station.
The dwarf family will have been usurped at one point by a rival family of dwarves known as the bloodstones. The bloodstones at this point in time have become essentially a crime syndicate as they have become more and more desperate with finding their goal. The head of the bloodstones is known as Calrund Bloodstone. A man willing to do anything to achieve his ultimate goal within the Orgidus system.
Which at this point I don't know what it is I want to do to bring these jerks in my group together. I have a basic idea of what direction I want the group to go in but I'm floundering on the details.

My players are a
tengu ace pilot envoy
drow icon technomancer
Ysoki outlaw mechanic
Android space faring technomancer
And a space caterpillar( read as mutant shirren) priest mystic
As you can tell my players are generally zany weirdos per the norm.

Any criticisms are welcome. Thank you.

The idea of doing a Thundercat based catfolk group would be pretty spiffy, plus yelling "THUNDER! THUNDER! THUNDERRR CATS !!! Breaks my heart a little

No no no. You want the SUNDER cats. they run in sunder everyone's equipment and then run off.

So I've been GMing Pathfinder for friends for awhile now
(mostly homebrew)
And I finally got around to reading the occult adventures book.
Which brought out a lot of interesting ideas.
Seeing the mesmerist class and the nifty abilities it gets got me thinking of possible villain ideas (ie a legato type character)
With the addition of the nemesis guidelines in UI I thought it'd be the perfect type of character to go with my current setting.

However here's my issue.
A mesmerist is a gish class by nature and while it does have some neat mind control abilities, it seems to be more melee/team combat oriented.

So how would I go about making an effective nemesis out of this?
Should I even use this or just go for a different class (such as a enchantment focused sorcerer)?
Or should I drop classes all together and give it abilities?

I would like to make this enemy memorable in a way and have an entrance set up so any and all advice is helpful.
