I think that Lafitte has a Siren-model fruit.
Laffite and the Alluring Sirens
Probably the most mysterious and in turn the most intriguing member of the Blackbeard Pirates, Laffite seems to be heavily inspired by the
Sirens. In Greek mythology, Sirens (not to be confused with Harpies or Mermaids) are described as humanlike beings with “alluring voices” which would “hypnotize” the sailors into jumping overboard. This matches the ability Laffite demonstrated when he hypnotized a bunch of Marines to open the Gates of Justice for the Blackbeard Pirates to crash Marineford.
The appearance of the Sirens wasn’t originally described in their first mention (Homer’s
Odyssey), but the first visual description has them appear as “
part woman and part bird”. The exact ratio of woman to bird varies, from just birds with women’s heads to something like a human with bird feet and bird wings; something like what Laffite looked like during his assault on Whitebeard....
And lastly, in Christianity, the word for “Sirens” is translated as an “Owl”; a bird which is famous for how quiet it is when flying. Laffite is noted to be completely silent when infiltrating the Marijoas, undetected by even the likes of Sengoku and Mihawk, the latter of which is known as “Hawk-Eyes”.
