Both UBs
Both are Ultra Beasts
The Both UBs connection is one of the special groups rules in the daily PokéWired Pokémon puzzle. Two Pokémon are linked by it when this holds: Both are Ultra Beasts.
It's not directional: it works both ways, so it doesn't matter which Pokémon goes on the left and which on the right. You'll meet it in Normal puzzles, and it can also show up in the Unlimited and Chain modes.
Special-group connections ask whether two Pokémon share a rare label — legendary, mythical, starter, fossil, baby, paradox and more — so they test your deeper Pokédex knowledge.
