After several of the Chaos Emeralds disappeared, Tails teamed up with Knuckles to set a trap for them. Reluctantly, he took apart his prized Tornado and rebuilt it into a trap. The thieves soon appeared and sprung the trap, but proved able to break out of it. Tails then watched in horror as Knuckles engaged the attackers only to be defeated by their leader and dragged off. Realizing that he couldn't handle this problem alone, he set out to get help from Sonic, Amy, and G.U.N. (StH: #191)
