Fiendish creatures are extraplanar creatures (typically an outsider, elemental, or magical beast native to another plane) with different alignments that can be summoned using various Summon Monster spells. This is in contrast to the various Summon Nature's Ally spells which summon natural creatures who are all of a neutral alignment. Warlocks have the ability to summon fiendish creatures.[1]
