CREATE TABLE power
( 
POWER_id INT NOT NULL AUTO_INCREMENT, 
name VARCHAR(255) NOT NULL, 
description TEXT NOT NULL,
CONSTRAINT POWER_PK PRIMARY KEY(POWER_id)
);

CREATE TABLE superheroPower

powerID INT DEFAULT(0) NOT NULL, 
CONSTRAINT SUPERHEROPOWERS_SUPERHERO_FK FOREIGN KEY(superheroID) REFERENCES superhero(id), 
CONSTRAINT SUPERHEROPOWERS_POWERS_FK FOREIGN KEY(powerID) REFERENCES power(id) 
);
