Chapter 3 Dr. Wave - Robinson's Family Techocolor Treehouse
Even though the Dr.’s personal life support systems were operational, he could sense that the aggressive life forms in the environment would pose a serious threat, sooner than later. Inspecting the escape pod, he thought he could modify its exterior light, to make it emit ultra-violet waves strong enough to keep out unwanted plants and bacteria, but not enough to harm him. He searched the pod for a tool kit. Someone had sense enough to leave a vibroblade, maybe they thought of the tool kit as well.
OOC: This would be a coincidental Forces 3/Life 2 effect to transform the light created by the pod into a weak anti-life field that would keep out plant life, bacteria, microbes, etc. without harming him.
