I've got Rawk's three upgrades, and will have some character development for him when he gets them.

[b]The King:[/b] When Rawk gave up his Cyber Swords and most of his Psychic abilities, he gained a scepter instead. This scepter makes Rawk like a Chess King. He has even greater control over his Pieces, and can use the scepter for attacks that are between a Bishop and Queen's in strength. He can fire them at a rate of five per second, or can shoot a potent blast by charging for two seconds.

[b]Bishop:[/b] Rawk can now summon Bishops to aid him in battle.

[b]Checkmate:[/b] A tandem attack between Rawk and his Pieces. Rawk maneuvers an enemy so he is surrounded, before the enemy is hit by a barrage of blows. If any allies are in range, then Rawk can include them in the attack as they see fit.

Also have Link's upgrades.

Silver Gauntlets- Allows Link to lift very heavy objects as if they were nothing. He still has a discernable limit, but he can lift objects up to the size of a small house without any negative effects.

Fire Arrows- Link fires arrows that are lit on fire. The fires are nearly inextinguishable.

Iron Boots- Allows Link to increase his weight by about a ton. He is nearly immovable with them on, but loses the ability to jump above water. He is severely slowed, but he can move normally underwater.
