If it’s the canon god of the Pokémon world it’s pretty underwhelming. If that’s just a myth in Sinnoh then it works okay. I like its gimmic with the plates and I like when mythicals have a clear link to other legendaries in some way (Mew, Darkrai, Arceus, and Keldeo).
Didn’t appreciate back in the day but like it more now ever since Let’s Go used Arcanine to replace the bike. Have thought about using it in Sword since I never really got far with one in the actual story.
