Aurorus not having Aurora Veil was mentioned before given the name and Aurora mentions in its dex entries, and the fact that it remains an Egg Move is bizarre for Gen 8, compounded by the fact ABOMASNOW can get it normally as a Level 1 move but not Aurorus. It has Reflect and Light Screen (moves they've been quite picky about since Gen 8+ movepool re-evaluation) so I don't see what flavor it's missing even beyond the Snow Warning Aurora-themed Pokemon like Ninetales. I bring this one back up like 5-7 years later because it baffled me for that long and we know Aurorus isn't in Gen 9 so it continues to go unaddressed.
Also Aurorus, the Specially-focused Fossil Pokemon characterized by Diamond-Shaped Crystals all over its body, has yet to be allowed to learn Power Gem in any form. A visible Gem Stone, Ore, or just something "organic" with a strong glow seems to be the main criteria for natural learning (which they play loose with in cases like Corsola, Nihilego, and Miraidon), and yet Aurorus isn't allowed to have it even via TM or Egg Move (they gave it to Nacli in Gen 9 of all things!) after 3 Generations in the game, one in which the move was a TM as noted
