S2E9 Multi-Tails

After a setback in a confrontation with Eggman, Tails grapples with feelings of inadequacy. Despite being the intellect of the team, he doubts his ability to support Sonic and the others effectively. Determined to change this, he invents a device that allows him to create multiple clones of himself, forming what he calls a "brain trust." However, the question remains: will Tails and his duplicates possess the collective intelligence needed to overcome Eggman's relentless schemes?
