Convergents and paradoxes

Klik - The Gear Pokemon - is a Grass-type Pokemon that lives near riverbanks. It uses sunlight to power itself and slowly rotate. It eventually evolves into Klak, the Gear Pokemon.
When it finally evolves into Kliklak, the Waterwheel Pokemon, it gains the Electric-typing. This Pokemon has the special ability Flowing Current, which causes it to gain a power boost to Electric-moves if it is raining or the terrain includes a water source.

Iron Stomach, the Paradox Pokemon, Normal/Steel-type.
Iron Stomach resembles a cleaning device said to have come from the future. Anything that enters it's stomach is broken down and used to power the machine further. The only issue is that due to an error in it's code, Iron Stomach has difficulty telling between trash and things it shouldn't eat.

Leaping Dragon, the Paradox Pokemon, Water/Dragon-type
This fearsome beast is said to be a super-ancient relative to Magikarp, certainly it is far stronger.
Leaping Dragon is a vicious predator and hunts constantly for it's next meal. Though it's jaws are strong, it's thick scales provide unparalleled defence capabilities. Supposedly, the specimens alive today have survived for over a million years.
