Li'l Boo

Li'l Boos are smaller Boos that appear in the game Super Mario RPG: Legend of the Seven Stars. They are found in the alternate dimension of Smithy's Factory. Li'l Boos are stronger than their weaker counterparts, but they share the same attacks. They even have a similar stat layout, with both having high Magic Defense, low Defense, and middling Magic Attack. However, unlike the weaker variation of Boos seen earlier in the game, Li'l Boos' Attack stat matches that of their Magic Defense.

Their name outside of Japan is perhaps purposefully ironic, as despite being smaller than other Boos they are much stronger. This irony is further cemented by the fact that Boos in the American version are known as "The Big Boo". Despite this, their Japanese name is simply High Boo, implying that they are if a higher status than other Boos and thus would likely have more power.
