Japanese name origin
The French name origin lists "aiguillon", meaning stinger, as a French name origin. Considering that the Japanese name is "Agoyon", and considering the word and Pokemon in question, I think "aiguillon" is a valid name origin for Agoyon. --Celadonkey 16:20, 4 January 2018 (UTC)
Speed Stat Trivia
If Naganadel's speed stat were 151, a prime number, its stats would total 570 like the other fully evolved Ultra Beasts. Seems interesting, like maybe it was originally supposed to have 151 speed, but someone would probably delete it immediately for being 'hypothetical' or something if I put it in the trivia section, so I'm putting it here.

Early design
KiranTheWitch from the forums asked James Turner about any revisions Naganadel had gone through before its design was finalized. He mentioned that at some point, Naganadel was supposed to have legs. Does it warrant mentioning in the article? https://twitter.com/KiranTheWitch/status/1080657917370494978?s=09 here's their conversation in question. Kikugi (talk) 10:29, 3 January 2019 (UTC)
Japanese Name Origin
Might it be more likely that 顎 means "barb" in this case, as a reference to it's many barbs/needles? 顎 can mean jaw but that doesn't seem likely given what we know about this Pokémon. Thoughts? Landfish7 05:13, 26 June 2020 (UTC)
