A neutral character (also called "true neutral") is neutral on both axes and tends not to feel strongly towards any alignment, or actively seeks their balance. Druids frequently follow this dedication to balance and, under Advanced Dungeons & Dragons rules, were required to be this alignment. In an example given in the 2nd Edition Player's Handbook, a typical druid might fight against a band of marauding gnolls, only to switch sides to save the gnolls' clan from being totally exterminated.
Most animals were originally considered true neutral, because they lack the capacity for moral judgment in general, guided by instinct rather than conscious decision. The 4th edition introduced an additional alignment called "unaligned" for creatures not sapient enough to make decisions based on alignment, even that of neutrality; this alignment is also used in the 5th edition.
