Zero's regular form. In this, he has a cape which enables him the power of flight.
Zero Custom, the Knight of Silver WingsEdit
After nursing Fenn to full health, Zero discovers that his friend's true form is that of the powerful Feather Dragon, one of Lacroa's most powerful spirits. By merging with the matured Fenn, Zero becomes the much more powerful Zero Custom, the Knight of Silver Wings. In this form Zero wears angel-like armor and has access to a Twin Buster Sword which can split in two. He also gains a number of powerful new attacks, strongest of which is the mighty Infinity Winds.
A Knight Gundam sworn to protect Lacroa and its royal family, Zero was spirited away to Neotopia two years ago in the hopes he would find a way to combat the Dark Axis occupation. He ultimately hooked up with Neotopia's own Gundam defenders when the Dark Axis launched a campaign there. Flamboyant and noble, Zero sees himself as something of a gentleman and has an ego to match. He's also a sucker for women, especially damsels in distress. When out of combat, he often uses his magic to produce magical flowers to annoy his team mate Bakunetsumaru, usually on the tip of his swords. Despite this Zero is an important figure in Lacroan mythology, which regards him as the 'Chosen One' who will save Lacroa.
When Lacroa first got invaded by the Dark Axis, Zero and the rest of the Knight Gundams went into war with them. However the battle went badly, with only five Knight Gundams remaining (counting himself). When the Dark Hole's prophecy revealed that Zero would save Lacroa, he along with Princess Rele were escorted to the Garden of Wisdom. Despite wanting to stay and fight, the other Knights reassured that they would do their part and that he should do his as well.
