Helios

As Samus ventured into the second Leviathan, she found it's guardian: Helios. This Mechanoid looks like a small round sphere with 4 tentacle-arm like appendages. Helios had 6 forms, but (save the 5th, and the 6th only appears when Samus beat another form) can appear in any order. The first form has Helios in the center of a large sphere of swarmbots. Samus avoided the rolling attack until Helios switched forms again. The second form was when Helios spreads out his swarmbots and lets them charge up blasts, these blasts were then released at Samus with lethal accuracy. The 3rd form, Helios formed a disk with 5 red points on it, Samus then blasted those points with seeker missiles. If Samus wasn't fast enough, the red points disapeared and Helios spun the disk at her. After Helios had taken a little damage, it would enter a tornado form. This form simply tried to tackle Samus, who in turn droped morph ball bombs, after Helios missed. After Helios has lost 2/3 of its health, it would create a humanoid form. Samus shot joints on it to knock Helios over. After being shot after its forms were crippled, Helios would enter his Final form. Samus could only truly damage Helios while it was in this state. While Helios' core was exposed, Samus fire Phazon bursts into it. Helios would defend itself with a slashing attack. After Samus beat Helios, she found the Hyper Missile.
