>>44201605>Solar blade>solar beamMy point still stands. They're collecting sunlight and converting into energy like a plant's photosynthesis, which is why it's grass-type instead of fire. This is why they both get a boost from sunny day.
Castform and weather ball become fire-type in its sunny form. Sunlight also boosts fire types by 50%. Groudon, a pokemon with a lot of fire-type moves in its move pool, has ability that brings about sunlight. Not to mention that primal groudon, which is a fire type, has an even more enhanced version of that ability.
Sun is definitely associated with fire-types, anon.
