Gatorclaws inhabit the Safari Adventure area of Nuka-World. They were created by Dr. McDermot for security purposes, using a combination of alligator and Jackson's chameleon genetic material, along with brain cells from a super mutant. The gatorclaw is coincidentally close in name and appearance to the deathclaw.
Identical in posture and general anatomy to a deathclaw, gatorclaws have minor external traits that reflect their alligator genetics. They have an elongated, sock-like head and no horns. Their back and tail are protected by heavy platelike scutes, lined on either side by dull spikes. Their claws are very short and more robust than their untampered counterparts. Their skin is a dull forest green, contrasting sharply with their pale greyish underbellies. They can sometimes be seen lying flat in the same manner that alligators do.
Strangely enough, they have no tongue. They have the same animation as deathclaws when they 'taste' the air with their tongue, but the Gatorclaw appears to just sniff the air. It has a glottis like a deathclaw, but the tongue model appears to have been excluded.
Their overall behavior is the same as that of the deathclaw, including walk cycles, attack animations, and idle animations. They still use their claws to attack, despite having an ideal jaw structure for biting attacks. They also do not appear to have any grabbing attacks seen in deathclaws, likely due to the decreased motor skills their stubby claws and heavier hands afford them.
Once their related quest is fulfilled, it's no longer possible to spawn any more, as the cloning machine will endlessly spawn Gazelle with no chance to end the process.
The most common and weakest variety of the gatorclaw, many can be found inside Safari Adventure and outside of Safari Adventure. The gatorclaw shares strong resemblance to the deathclaw in the base game of Fallout 4.
