Crystal
During the study of this POKéMON, it was discovered that its components are not found in nature.
Ruby
VOLTORB was first sighted at a company that manufactures POKE BALLS. The link between that sighting and the fact that this POKéMON looks very similar to a POKE BALL remains a mystery.
Sapphire
VOLTORB is extremely sensitive - it explodes at the slightest of shocks. It is rumored that it was first created when a POKé BALL was exposed to a powerful pulse of energy.
Emerald
It bears an uncanny and unexplained resemblance to a POKEBALL. Because it explodes at the slightest shock, even veteran TRAINERS treat it with caution.
FireRed
A life-form whose identity is unknown. It is said to SCREECH or suddenly SELFDESTRUCT.
LeafGreen
Usually found in power plants. Easily mistaken for a Poke Ball, they have zapped many people.

Voltorb: Usually seen only in power plants, it is sometimes seen in towns, apparently using the power lines to travel.
The user attacks uncontrollably for five turns; this move's power doubles after each turn and also if Defense Curl was used beforehand. Its power resets after five turns have ended or if the attack misses.

All Pokemon in the user's party receive 1/2 damage from Special attacks for 5 turns. Light Screen will be removed from the user's field if an opponent's Pokemon uses Brick Break. In double battles, both Pokemon are shielded, but damage protection is reduced from 1/2 to 1/3.
Almost always goes last; if an opponent strikes with a Special attack before the user's turn, the user retaliates for twice the damage it had endured. In double battles, this attack targets the last opponent to hit the user with a Special attack and cannot hit the user's teammate.

All Pokemon in the user's party receive 1/2 damage from Special attacks for 5 turns. Light Screen will be removed from the user's field if an opponent's Pokemon uses Brick Break. It will also last for eight turns if its user is holding Light Clay. In double battles, both Pokemon are shielded, but damage protection is reduced from 1/2 to 1/3.
Power is determined from the speeds of the user and the target; stat modifiers are taken into account. Max power, 150 BP, is achieved when the user is much slower than the target.
Almost always goes last; if an opponent strikes with a Special attack before the user's turn, the user retaliates for twice the damage it had endured. In double battles, this attack targets the last opponent to hit the user with a Special attack and cannot hit the user's teammate.
This move is temporarily replaced by the target's last move; the replacement move will have 5 PP and become part of the user's moveset until the user switches out or the battle ends. Mimic copies attacks even if they miss or the user has immunity toward their type; it cannot copy itself, Struggle, Transform, Sketch, Metronome or moves that the user already knows, and it will fail if the target has yet to use a move.
The user takes one-fourth of its maximum HP to create a substitute; this move fails if the user does not have enough HP for this. Until the substitute is broken, it receives damage from all attacks made by other Pokemon and shields the user from status effects and stat modifiers caused by other Pokemon. The user is still affected by Tickle, Hail, Sandstorm and Attract from behind its Substitute. If a Substitute breaks from a hit during a multistrike move such as Fury Attack, the user takes damage from the remaining strikes.
Almost always goes first. The user is left with at least 1 HP following any attacks for one turn, but the move's success rate halves with each consecutive use of Protect, Detect or Endure.
The user attacks uncontrollably for five turns; this move's power doubles after each turn and also if Defense Curl was used beforehand. Its power resets after five turns have ended or if the attack misses.
Does nothing if the user is awake. If the user asleep, it randomly performs one of its attacks. Rest will fail if it is selected. Sleep Talk's generated attacks do not cost PP, but it cannot generate moves with 0 PP, itself, Assist, Bide, Disabled attacks, Focus Punch, Metronome, Mirror Move, Uproar, or attacks with a charge-up turn like Fly or Skull Bash. (Moves with a recharge turn like Hyper Beam can be generated.)
