The beginning

Am onslaught began when an alien force called Dricutis, attacked, firstly they came to earth pretending to be good,but when they noticed that the humans had the energy, arcro, within them ,they decided to trade the arcro with technology

But the humans disagreed because they found out that the Dricutis had evil plans for the arcro,the Dricutis then started the war.

The humans fought back but the Dricutis were too strong to defeat, the war then lasted for three years with the humans always losing.

Suddenly, a group of humans discovered a new way to cultivate arcro which resulted in a new energy, steorix energy, but not all humans were strong enough to wield the steorix energy

Some tried but died, others were either lost in inter-dimensional portals or shrink to parasite level, those who were able to wield it came together and became Z-steo guardians and with the new energy they created new abilities.

The Dricutis struck again but this time the guardians fought back which after defeating them created a magical barrier preventing the return of the Dricutis.

Years later

After the death of the guardians, the steorix energy was forgotten but the new abilities were not. Because no-one else was able to wield the steorix energy ,they created stero-bots, small elemental robots about three feet tall with the ability of transforming into armour- like suit for their possessor, also every stero-bot's demeanour was in line with its possessor's ability.

And that was how the humans survived battles since, the death of the guardians, but not everyone was certified to have a stero-bot....
