The bulk update request #11854 is pending approval.

create alias omega (1) -> omega_(disambiguation) (0)
create alias omega_(character) (2) -> omega_(disambiguation) (0)
create alias omega_(artist) (4) -> omega_(disambiguation) (0)
change category omega_(disambiguation) (0) -> invalid

Reason: Lots of tags under the name "Omega."

Not sure if omega_(character) should be included since I found one I could not disambiguate already.

yeah disambiguate omega_(character) as well.

Adding omega_(artist) too.

The bulk update request #11857 is pending approval.

create alias omega_(sonic) (0) -> e-123_omega (250)
create implication e-123_omega (250) -> sonic_the_hedgehog_(series) (129466)

Reason: tangentially related, since this character has the most populated tag of a character with this name, and a portion of usages of omega (12/256, ~5%) were posts with this character.
