Prior to the series' events, it was revealed by Ja'em Mk'rah that Makino's next target was Earth. Ja'em went to Earth and there he created N-Tek alongside with Forge Ferrus, Molly McGrath and Miles Dread. The organization's main goal, as revealed in Earth Under Siege Part Two, was to prevent Makino from absorbing Earth and destroy its population with his Alphalink, which is a large weapon almost the same size as a planet used by him to absorb planets.
During an undetermined around of time, Makino attacked Earth with countless Ultralinks. At first, N-Tek was losing the battle, until Ja'em and Steel arrived and managed to defeat Makino's troops and save the day. According to Jim in The Wrath of Makino, Earth remained in peace during sixteen years until Makino attacked it again.
During Season 1's finale, Earth becomes vulnerable thanks to Dread, who betrayed N-Tek a long time ago and became Makino's ally. He manages to disable the shields around Earth, thus making it vulnerable to Makino fully absorb it. Makino sent its second fleet to conquer Earth, but Maxwell McGrath (Jim's son) and Steel managed to defeat the Ultralinks once again.
After its crushing defeat, Makino stayed months without attacking Earth and waited until he could send four evil Ultralinks on a meteor shower. When the Ultralinks were defeated by Max Steel and N-Tek, Makino started to send more Destroyers and other minions, but they were once again defeated by Max Steel. Makino then found a way to fight Max Steel by himself. After he arrived on Earth, he created a plan consisting in turning Forge Ferrus into an Ultralink so he could take down N-Tek with a large fleet of Ultralinks and Dread Naughts and in meantime Makino would fight against Max and Steel.
Eventually, Steel was captured by Makino and his plan was being very well executed. By creating a wormhole, Makino would manage to bring the Alphalink to absorb Earth. However, Makino was ultimately defeated by Max Steel with his brand new Turbo Mode. After its crushing defeat, Makino got angry and even angrier after discovering about Dread's betrayal and decided to go to Earth in full speed. This took around forty days.
In meantime, N-Tek prepared itself for the biggest battle yet by building a platform named Daedelus, but they ultimately decided to use the Turbo Star, a weapon created by Jim McGrath sixteen years ago capable of launching powerful rays of concentrated T.U.R.B.O. Energy.
