Sentinel 752

Sentinel 752 is a dark gray/light black colored humanoid robot composed of small segment-like pieces composed of incredibly strong metals. It can absorb other metals and turn them into its own metal. Its segments can independently detach and reattach as well as float and fly using Zeta Magnetism. It has no mouth, but a holograph display showing audio bands from its voice, which it seems to emit electronically. Its eyes are glowing holographic eyes. He has the ability to form energy weapons such as swords and lasers.

Origin
Three thousand years before present day, the Precursors initiated the Sentinel Project to help them fight a three hundred year war with the Tachyons. 1,000 Alpha Sentinels were made, each of them different test models. Each of them were powerful soldiers, but they fell one by one until only Sentinel 752 and his squad were the last one alive. He was drastically stronger than the others. Together, 752 and his squad faced an army of Tachyons and cut them down with ease. However, they sustained heavy damage in battle with their general, who had a Tachyon crystal. His squadmates were swept aside easily. When Sentinel 438 caused a powerful explosion, it damaged the General's armor enough to allow 752 to finish him. Upon contact with the crystal, 752 absorbed it and became even stronger.

2500 years later, Sentinel 752 crash-landed on Earth in modern-day Nevada. His presence attracts aliens to the location frequently. Someday, he will rise up again to fight a new threat...
