Gone To Seed

With the Seed's shield destroyed, you can now fly to it and attempt to destroy it. After bypassing the locks in the hallway, you'll come out to the center of the Seed, and the next boss fight.

Boss Fight: Helios

Helios is a small robotic entity that's been corrupted by phazon and being used to guard the Leviathan seed. He uses swarmbots to protect himself, but with a little perserverance you can bust through his shield and take him out.

Helios has a lot of different phases that he'll use to bust you down. The only one in which you can really hurt him, however, is when he sheds all of his swarmbots and opens his chest and comes after you. Switch to Hypermode in this case and blast him; you'll need to do this at least three times to completely wipe him out.

(Note that thanks to the Wii's great three-slot save system, we accidentally saved after beating Helios but before recording a video of him. So no video! Sorry! Note also the phases listed below are in no particular order.)

Phase One: Swarmbot Ball

At the beginning of the fight, Helios will summon his swarmbots and make them into a protective sphere around him, then drop down to the ground and begin rolling around, attempting to smash you. Fire away at the shield here, aiming for Helios himself. If you hit the swarmbots, you'll periodically cause them to pop and drop some health, but your goal is to hit Helios and make him flash yellow. While it won't do any damage, you'll get him closer to the part of the fight where you really can hurt him.

Phase Two: Swarmbot Disc

This is a bit of a longer session. Helios will periodically move all of the swarmbots out to form a circle around him. If you give him time, he'll eventually turn into a sawblade of sorts, whizzing around the air and attempting to cut you with the swarmbots. Every so often he'll slow down and materialize five red engines in the air between him and the swarmbots; he'll charge them up and attempt to use them to fire on you. If you can, lock onto the engines with your swarm missiles and hit all of them at once (they'll periodically phase out of existance and be immune to missile fire, so you'll have to get lucky on the timing). If you manage to do so, the circle will bend out of shape and you'll be able to fire on Helios directly again.

Helios has numerous forms that he'll use on you.

Phase Three: Swarmbot Lasers

The swarmbots will detach from Helios and form small pods, like they do when you encounter them in the wild. They'll charge up slowly and will eventually begin firing on you. It's easiest to just avoid damage here by shifting to Hypermode and firing on the pods as they begin to turn white; that'll disperse them and prevent them from hitting you.

Phase Four: Tornado

Helios drops to the ground and sends the swarmbots above him to create gusts of air. Roll up into your ball form and use bombs on him when he pauses to cause damage and disrupt this form.

Phase Five: Robot

The swarmbots support Helios by forming two legs and arms for him. He'll periodically attack you by summoning huge balls of energy onto his "hands" and throwing them at you. You need to shoot the arm joints out here first; they're easiest to hit just before the balls are launched at you. After the arms are shot off, you can try to take off one of the legs by shooting through the swarmbots at the leg joints. If you can get one of the leg joints to fall off, then the form will dissipate, letting you shoot Helios himself for a few moments.

Finish The Fight

Helios' individual forms aren't too bad; just try to continue to hit him in the body with your normal shots. If he's flashing yellow, then you're making progress towards the point of the fight where his body breaks open and he's vulnerable; at those points, shift to Hypermode and unload on him. A few rounds of that and he'll perish, netting you the Hyper Missiles.
