This has been a mess for several years so I present a bunch of stillborn failed and unfinished tables. My current mutation system working well and will be basis of the class I eventually create. I may still try a mutation spell list one day because the robot abilities as a spell list worked. I will do a cyber mutation list in style of recent mutation series which could be for cyborg or tech monsters. There are salvageable ideas here and feel welcome to have a crack at stealing stuff or let me know if any bits worth working on. I will put new comments in [Brackets]. Four years of failure here.
These are for benign mutations with limited possible utility.
Ive meant to do Robots, Mutants, Cyborgs and Psion as a character classes just for Psychon. My "Psionics as just another spell list system" has worked without a class for several years. Robots (half done) and Cyborgs will use same "spell list".
I also have mutants in my fantasy dnd game so I'm including some mutant variant tables for various strains of mutant bloodlines. Plus a standard d100 for non-allied mutants.
[Some of these worth expanding in current format but this could be a shorthand till then]

Mutation Tables
I decided levels like spell then body location best way to do this.
Choose default on d10 or roll d100
d10 Mutation Location
1 Dermal default skin colour
2 Hair default is coloured
3 Cranial default is horns
4 Cerebral default is neurological phobia
5 Sensory default is eye colour
6 Limbs default is shrink 1d10cm
7 Body shrink d10cm
8 Respiration
9 Metabolic
10 Circulatory
Ideas for Mutation by levels
0 Zero Level is for mostly cosmetic features
1st Level provide some minor bonus, usually physical
2nd Level start getting to be minor superhuman with mostly physical
3rd level start getting more spectacular Alpha class energy or psionic powers
4th level increasing powers over matter, some monstrous chimera
5th level powers like teleport, disintegrate
6th level increasingly weird abilities
7th level self resurrection, time travel, stasis field, alchemist touch, create life, gate
