There is an official hopeless character rule. If you end like this:
Out of generosity I will allow you 1 re-roll anywhere on character creation.
You will start at 1st level. Your starting equipment is in the introduction post above (#6). You can choose if your bow or your melee weapon is of good quality. The other will be of primitive quality. I feel generous and will you also allow to start with leather armor equivalent (+2 AC, max Dex +6, no check penalty).
I will use a slightly modified mutation table from the Omega World Polyhedron article. It isn't OGL, so you will roll and I tell you your mutation.

You may choose your name, gender and mutant subtype.
Human mutants have a change to be treated as humans by ancient scanning devices.
Animal mutants start with one natural weapon.
Plant mutants gain a +2 to saves on every effect that plants are normally immune to.

Let's start rolling!
Roll 2d6+6 for each ability in order.
Roll 2d4 to determine the maximum number of mutations. You have to declare the exact number before you start rolling for them.
Roll a d% for each mutation. 1-85 = beneficial, 86-100 = defect.
Roll a second time a d% for each mutation.
