Many times when creating a creature, I take apart the stats, making small adjustment to AC, dmg, skills, etc. Not for the Pink Unicorn, I just wanted to update their magic to better enable them to fight/face lawful creatures, especially ones that try to change others will especially thru magic.

SPECIAL ABILITIES
Magic Circle against Law (Su) This ability continually duplicates the effect of the spell. A unicorn cannot suppress this ability.
Magical Strike (Ex) A unicorn's gore attack is treated as a magic weapon for the purposes of damage reduction, It is equivalent to a +1 magic weapon. If the horn is removed, it remains a magic weapon. It takes a unicorn a month to regrow a new horn. The removed horn retains its magic for 1d100 days.
Wild Empathy (Su) This works like the druid's wild empathy class feature, except the unicorn has a +4 racial bonus on the check, +8 vs chaotically aligned. Unicorns with druid levels add this racial modifier to their wild empathy checks.
Magical Light Spray is an at will ability. It can either shoot a beam of light out to 150 ft from its horn alternatively they can change any magical light into a kaleidoscope of bright multi-coloured display out to 50 feet. Lawful creatures in this kaleidoscope suffer a -2 to attacks, saves and skill checks. Non-lawful creatures with at least +5 skill ranks in dance gain a +2 to attacks, saves and skill checks if in the magical light.
Negate Charm: Any creature under the effects of charm is freed from the compulsion. (DC 26)
A Pink Unicorn is a sylvan legend, a unicorn with pink streaks of hair and a bright pink horn. It is a charming figure, always looking to make allies to help it in it's tasks, but makes sure that they help it willingly. While their standard kin seems focused on hunting evil, the pink unicorn is devoted to ensuring lawful forces cannot hurt or weaken others. They enjoy acting spontaneously, free to their whims and despise when others enforce their will on weaker creatures. They are welcomed among their sylvan kin, since there are few lawful faeries. Couples in love are sometimes blessed with the appearance of a pink unicorn during moments of coupling or marriage, their appearance foreshadows happiness and good fortune for their future.
