Totodile
The Big Jaw Pokémon
Type: Water
Official Registration #: 158
Entry: One of three pokémon traditionally offered to new trainers at the beginning of their journeys in Johto. A small but hardy alligator pokémon, totodile possess jaws strong enough to crush the front bumper of a car. Although it is frequently advised by experts to take caution when handling this pokémon, even those experts sometimes have difficulty avoiding injury from a totodile bite. So, logically, certain Johtonian researchers have reached the admirably sage conclusion that this is the perfect pokémon to offer to young and heavily inexperienced trainers.

Croconaw
The Big Jaw Pokémon
Type: Water
Official Registration #: 159
Entry: The evolved form of totodile, by battle experience. Croconaw’s primary form of attack is to use its huge, powerful jaws to bite down onto its opponent. Once latched on, it never lets go until it loses its teeth, which grow back harmlessly within a day. So to the young and inexperienced trainers mentioned in the previous entry, rest assured that your croconaw’s teeth will grow back shortly after they lose them, which should be one less thing to worry about as you seek medical attention for the reason why your pokémon lost its teeth in the first place.

Feraligatr
The Big Jaw Pokémon
Type: Water
Official Registration #: 160
Entry: The evolved form of croconaw, by battle experience. Despite its bulky appearance, feraligatr is a swift pokémon, capable of rushing at an opponent with blinding speed. Once it corners an opponent, it tears into its victim with its massive jaws, savagely tearing them apart within seconds.

Which, in combination with the damage the other two evolution lines can do to a human being, should explain why the author is immensely curious as to how a certain professor gained permission from the Johto League to hand out starters.
