Here's a crazy chart from Brian Blume, written for when your Metamorphosis Alpha mutant wanders into an operational bionics lab. This is one of those tiny little quarter page articles that appeared in the earliest issues of the The Dragon. In this case, it's issue #13, April 1978.
Die Roll/Replacement/Hit Points/Effect
1-3 One Arm 10 Increases strength. +1 die of damage
4-6 One Leg 10 Increases strength. -1 for opponent to hit. Double speed if both legs.
7-8 One Eye 5 Infra Red & Ultra Violet vision. As Heigh. vision if both eyes.
9-10 One Ear 5 May hear above & below normal ranges. As Heigh. hearing if both ears.
11 Nose 5 As Heigh. smell.
12 Heart 5 Reduces fatigue.
13 Lungs 5 May extract oxygen from water.
14 Digestion 5 May live on rocks, sand, etc.
15-17 Brain 10 50% chance to forget any given fact or item’s operation each occasion (defect).
18-20 Torso 30 -2 to hit for both player and his opponents.
I don't have a copy of MA in front of me, but Heightened Vision, Hearing and Smell are undoubtedly on the mutations charts.
Does anyone else love how getting a bionic brain is a bad thing?
