Although Lion-0 has the body of an adult, his accelerated growth means that his physical strength has outpaced his emotions, and he still has a lot of growing up to do before he can achieve the kind of maturity that every leader needs. Luckily, a seasoned warrior is ready to help him master his temper with some painful combat lessons! In the aftermath of the Third-Earth-shaking events in the first story arc, Cheetara takes center stage for 'Training Day,' a special standalone issue written and drawn by guest author STEPHEN MOONEY (The Rocketeer: The Great Race, Half Past Danger), who also contributes a cover for the issue together with series stalwarts DAVID NAKAYAMA, LUCIO PARRILLO, DECLAN SHALVEY, JAE LEE & JUNE CHUNG, and IVAN TAO!
