This also means that they can also mega evolve which opens up a lot of posibilities

Wow, mythical megas now where have I seen this?

no its a ultra beast

What

Zeraora is a mythical Pokémon.

ok update your right apparently huh guess they made a mistake in their video as well, sorrry saw this from the vid from Nintendo then a few minutes later I saw a reaction video talking about this being a ultra beast

the irony is I corrected them in the comments that solgaleo and lunala arn't ultra beast

Sorry Abel my fault

Although this could mean mega for other mythicals personally I would do a Mega Genesect and have technoblast become a stronger version of tri atack and have 170 base power and work like body press but deal all drive damage so fire, water, ice and electric damage (which ain't op cuz of mega zygarde)

which means megas could be possible for:
Nihilego (UB-01 Symbiont)
Buzzwole (UB-02 Absorption)
Pheromosa (UB-02 Beauty)
Xurkitree (UB-03 Lighting)
Celesteela (UB-04 Blaster)
Kartana (UB-04 Blade)
Guzzlord (UB-05 Glutton)
Poipole (UB Adhesive)
Naganadel (UB Stinger)
Stakataka (UB Assembly)
Blacephalon (UB Burst)
Necrozma ("UB Black") {No official name for it this UB Black is just from the Anime}

Necrozma is a legendary but he is also a UB it’s just some people get confused about that and he’s actually the god of light so I feel like in your legends region he would be (UB light)

well that complicates things with another mon I made (this was a long time ago considering it was my 2nd one so ye) imgflip.com/i/a6b9d3

never did make the dex entry for it or give it name its name was kinda like Xurketree (circuit and tree) and combined eel and light somehow I don't remember what it was called tho
