Sometimes when I'm out running my mind goes wandering. Here are some powers you could have in a GURPS game. They are arguably useful, but deeply questionable nonetheless.
X-Ray Vision Vision
6 points. You see distinct traces whenever someone views an area with their X-ray vision. This power doesn't reveal people, but the extent of their X-ray vision is clearly visible to you, and you can use it to deduce their location.
Detect (Rare; X-Ray Vision; Reflexive, +40%; Vision-Based, -20%) [6]
Ringtone Replication
6 points. You can accurately mimic any ringtone you've heard, and have an extensive repertoire of memorized ringtones to call on. If you have the Mimicry (Electronics) skill, you can roll against Mimicry rather than IQ to use this ability.
Mimicry (Accessibility, Only ringtones, -90%; Voice Library, +50%) [6]
Recover Teaspoons
6 points. By calmly concentrating for 30 seconds, you can cause lost and 'borrowed' teaspoons within 32 yards to teleport to your location. The ability is subtle enough that colleagues don't notice anything; however, the strain it puts on your body leaves you paralyzed for 1 minute, with an HT roll to recover once per minute thereafter. As such, it's best used when you can guarantee some privacy.
Affliction 1 (Accessibility, only misplaced teaspoons, -100%; Accessibility, Useless under stress, -60%; Advantage, Spoon Warp, +1%; Area effect, 32 yards, +250%; Backlash, Paralysis, -150%; Emanation, -20%; Malediction 1, +100%; No Signature, +20%; Requires Concentration, -15%; Takes Extra Time (x32), -50%) [6].
Spoon Warp is Warp (Anchored, afflictor only, -40%; Blind Only, -50%; Exoteleport, -50%; Modified Carrying Capacity, 0.05 lb, -90%) [20], reduced to [1] by GM fiat to represent its realistic value.
Detect, Evil
60 points. You are capable of supernatural feats of deduction and preternetural sensitivity, but drawing on your gifts risks imperilling your very soul. When you activate your detective powers, you gain a +4 bonus on Body Language, Criminology, Detect Lies, Intelligence Analysis, Interrogation, Observation, Savoir-Faire (Police), Search, Shadowing, and Streetwise. Displays of talent also gain a +5 reaction bonus from police officers and PIs. Alternatively, by meditating for a few seconds, you can attune your mind to virtually any substance or object of interest, and sense them at a distance. However, each use of your powers is a diabolical bargan that requires a Will roll to activate - for good reason!
When you use your powers, you are wreathed in a choking fog of sulphurous brimstone, and a withering aura of evil. Your eyes glow red, teeth sharpen, and bony spines extend from your temples and vertebrae. All reaction rolls incur a -4 penalty from anyone who can observe these; animals react at -8 instead, while those who see animals' reactions or have Animal Empathy take a further -1. Your presence causes grass to wither and insects to curl up dead.
Thanks to your diabolical appearance, while channeling these powers, you suffer -1 to your Disguise and Shadowing skills, and others gain +1 on attempts to identify or follow you (including their Observation and Shadowing rolls), or +3 in outdoor environments. They also gain a +2 on rolls to deduce the truth behind your abilities.
Cruelty seeps into your mind, making you cold to the emotions of others (see Callous, p. B125) and bestowing 20 points of Corruption each time you accept your infernal bargain (see GURPS Horror, pp. 146-8).
While you channel evil power, you are vulnerable to "turning" by particularly holy individuals. Worse, if you perish under its influence, your soul will go straight to the Hells! Even at the best of times, your aura is steeped in second-hand evil - you can stride unharmed through the shrines of dark gods and wield their artefacts, but you balk at the powers of goodness as though you were yourself an agent of Evil.
Functions and Detects as Evil [0] + Natural Copper 4 (Corrupting, -20%; Temporary Disadvantage, Bad Smell, -10%; Requires Will, -5%; Temporary Disadvantage, Callous, -5%; Temporary Disadvantage, Damned, -1%; Temporary Disadvantage, Detect as Evil, -1%; Temporary Disadvantage, Frightens Animals, -10%; Temporary Disadvantage, Lifebane, -10%; Temporary Disadvantage, Unnatural Features 3, -3%) [34] + Modular Abilities 30 (Divine Inspiration; Trait-Limited, Only Detect, -50%; Corrupting, -20%; Temporary Disadvantage, Bad Smell, -10%; Requires Will, -5%; Temporary Disadvantage, Callous, -5%; Temporary Disadvantage, Can be Turned by True Faith, -1%; Temporary Disadvantage, Damned, -1%; Temporary Disadvantage, Frightens Animals, -10%; Temporary Disadvantage, Lifebane, -10%; Temporary Disadvantage, Unnatural Features 3, -3%) [26].
Anti-Material Rifle
Take the stress out of mortal combat by imaginging your enemies nude? Not content with laser cannons and monomolecular blades, you have sought out or invented the ultimate weapon. Roll against Guns (Rifle) to attack a target within 100 yards, with normal range penalties (p. B550). You can aim to benefit from Acc 3. On a successful attack, you deal 5d corrosion to creatures and objects made of cloth. The weapon doesn't harm other targets, but any fabric they wear has its DR reduced by 1 for every 5 points of damage rolled.
Since it's a weapon, your rifle can be destroyed (DR 10) or stolen (with a Quick Contest of DX or ST).
Corrosion Attack 5 (Only fabric, -80%; Based on Guns (Rifle), Own Roll, +0%; Breakable, DR 6-15, -10%; Size -1 or -2, -20%; Can be stolen, Quick Contest of DX or ST, -30%; Superscience, -10%) [10].
Curse of Inevitable Death
You can afflict your enemies with a terrible curse, if you're willing to pay the price. If your enemy loses a Quick Contest of HT vs. your Will, they are subject to constant misfortune - the first to suffer, the last to benefit, and always at the GM's whim. However, you die immediately and unpreventably from natural causes.
Affliction 1 (Disadvantage, Cursed, +75%; Malediction 1, +100%; Temporary Disadvantage, Terminally Ill (One Month) (Time-Spanning (One Month Prior) +50%), -150%) [13].
