GURPSよろず

　生理学 --specialized limb structure, high strength-to-mass ratio, etc. --can justify Super Jump for realworld creatures such as frogs and grasshoppers. It isn’t realistic for giant animals and monsters modeled on these beasts . . . but that doesn’t stop them from showing up in fantasy. This ability is also popular with mecha, robots, and supers. Some simply have hydraulic jacks or unnaturally powerful legs, but two other possibilities are common:

「噴射」s:
　「噴射」s of energy or matter powerful enough to provide Super Jump are sufficiently noisy and dangerous to rate 「迷惑」 (-5%). A rocket with a fixed burn has Full Power Only (-10%) --and one of Horizontal Only (-25%), Projectile (-20%), or Vertical Only (-25%), if it can’t be steered.

Levitation:
　Telekinetics and gravitycontrolling supers not gifted enough to fly can still make amazing leaps.
Most have either Lighter Than Air (-10%) or Maneuverable (+50%), and those that use antigravity should take Planetary (-5%), too.

■代替案（Alternatives）
　Anyone considering Super Jump should read 跳躍 (p. B352). A few extra points of 基本移動力 can give a modest boost in jumping distance -- and improved groundspeed in the bargain.
「高速移動」 (Ground) (p. 45) is an even better deal for those who like to make their mighty leaps at a full run.
The ability to get airborne and stay there is 「飛行」 (p. 50). This is also the best value for individuals whose desired level of Super Jump --after modifiers --costs more than 「飛行」 with comparable modifiers. Those looking only for the ability to reduce damage from a fall should consider 「空中バランス」 (p. 43).
Martial artists familiar with secret acrobatic techniques are more likely to have the 八艘飛び skill (p. B196).

■追加特別増強（New Special Enhancement）s
Bouncing:
　You can rebound like a rubber ball. Your Super Jump works normally, but you also get a roll against the best of DX, 軽業, or 跳躍 when you experience a fall or collision --deliberate or otherwise.
Roll at -5 per multiple of your jumping Move, or fraction thereof, by which your velocity exceeds your jumping Move. Success means you take no damage and rebound with 90% of your impact velocity. If this doesn’t exceed your jumping Move, you can choose to stop instead; otherwise, you must bounce. Failure means you take normal damage and stop (“Splat!”). +50%.

Maneuverable:
　You can make midair course corrections. Calculate distance and “hang time” as usual, but while airborne, treat your jumping Move as air Move, exactly as if you had 「飛行」. For instance, if you can jump 100 yards at 20 yards per second, you can “fly” at Move 20 for five seconds before landing. Maneuverable is mutually exclusive with all of the special limitations below except Planetary. +50%.

■追加特別限定（New Special Limitation）s
Full Power Only:
　You must always jump your maximum distance when you use Super Jump. The only way to make shorter hops is to jump without using this advantage. -10%.

Horizontal Only:
　You can only increase your horizontal (broad jump) distance. Your ability doesn’t benefit high jumps, and has no special effect on falling damage. -25%.

Lighter Than Air:
　You jump by becoming lighter than air. For each second you’re airborne, your landing zone drifts a yard in the direction the wind is blowing per 5 mph of wind speed. For instance, if you’re in the air for three seconds in a 20 mph wind from the west, you’ll land 12 yards east of your intended target. -10%.

Planetary:
　You jump by “pushing off” against a planet’s gravitational or magnetic field. Your ability is useless in the absence of a planet. -5%.

Projectile:
　You can only launch yourself directly at your objective.
You’re an unguided missile, spinning out of control! You can do nothing while airborne, and have no active defenses. Make a DX or 跳躍 roll on landing. Failure means you collide with your target or the ground -- unless you intended to do so, in which case you miss and crash into something nearby. In either case, you suffer full normal collision damage. -20%.
Vertical Only: You can only increase your vertical (high jump) distance and reduce falling damage. Your ability doesn’t benefit broad jumps. This is mutually exclusive with Horizontal Only. -25%.

■パワーアップ（Powering Up）
Any power that explains 「飛行」 as levitation --elemental (e.g., Gravity or Magnetism) or supernatural (most often 「サイコキネシス」) --could justify Super Jump as a lower level of the same ability. Air, Fire, and other elemental powers might generate “jump jets.” Body-control powers are a third option, be they chi-based (“body lightening”) or biological (an adrenaline burst). 才能 adds to DX and 跳躍 rolls to take off and land, and to rolls to hit with jumping slams or kicks while using this ability.
