哪

This reading is locked to one word - 哪吒, the boy deity. Nowhere else. The syllable né here is a transliteration choice (the name traces back to a Sanskrit source, Nalakuvara, shortened over centuries), so 哪 was repurposed purely for its sound. If you see 哪 anywhere outside the name 哪吒, it's the question word nǎ, not né.

Nezha is a rebellious child-deity from 封神演义 and 西游记 - wind-fire wheels, fire-tipped spear, the cosmic ring 乾坤圈. The 2019 animated blockbuster 哪吒之魔童降世 made him a pop-culture flagship of the 国漫 (Chinese animation) revival.
