Appearance: Tundra, as might be gathered, is an ice Navi. His body is mainly comprised of bluish, semi-transparent ice, and where there isn't ice coverage a dark blue undersuit can be seen. Most of his face is covered by an icy mask, slightly spiky with a few holes for vocal communication on the Net. The mask continues up to his eyes, which are essentially glowing blue polygons between the mask and helmet. Tundra's helmet is sleek yet still serves as the base for many icicles which jet upwards and back. His chestpiece is also adorned with icicles, and the 'armor' continues to modest icy pauldrons and icicles protruding from both his kneecaps and his elbows. Tundra is not a bulky navi, but his armor gives his profile a bit of thickness -- especially the spikes.
Personality: Tundra is driven. Not to avenge his family or to become the most famous Navi on the net, but driven in the areas of self-improvement and the betterment of all around him. He battles mainly in self-interest, but won't hesitate to step into a conflict if he feels something is truly wrong (or important). He rarely "loses his cool," instead choosing to keep anger in check until it's useful to him. Tundra also dislikes letting his ego rule him, but he is by no means a humble Navi. In short, Tundra is no paragon, but but uses his skills so as to grow stronger and keep to his values.
Custom Weapon: Usually, Tundra uses an ice blade which protrudes from his wrist; basically, a sword carved from a hunk of ice and attached to his right arm. When he wants to use battlechips or change the form of the sword, it shatters and the new weapon (i.e. a Cannon) slides forwards from his arm. The weapon is then coated in a shimmery film of ice from where it touches Tundra's arm forward. It can be either translucent ice (a shadowy form under a coating of ice) or a hunk of ice made to look like the weapon.
