2. Who knows why.

Lol, Spink.
Kenji Armor Descriptions:NormalColors: Navy Blue (Main body), Black (Armor plates, other extras), Orange (trim/designs)
Shape: Shoulders are rounded off in a half-octagonal style (Ex: Sado's right arm <-Link); Metal plates cover lower arms; Twin spikes that stretch halfway down his back, opens to reveal short distance jet boosters (Kenji doesn't realise this for a good while); Helmet is very similar to a BMX helmet; Kanji for "samurai" appears on chest armor, appearing like this (<-Link). If there were an Alt. Kenji somewhere out there, the trim would be in red instead of orange.
Weapons: Same as normal. Ki katana glows orange rather than blue when Ki is flowed through it. More Ki turns the glow brighter rather than darker.
Activation process: Does some kind of action pose/move, then says "Activation."
Inactive form: Metalic wristband on right arm (Armor extends from there) (Color: Navy Blue)
CorruptedColors: Same as above, except the blue turns dark turquoise and the orange (or red) becomes duller.
Shape: The shoulders become less blocked off and instead become covered in spikes. A spike forms on the back of Kenji's boots. The helmet becomes more streamlined, and spikes form on the back.
Weapons: Nothing different, except the color of the Ki when being charged turns duller.
Activation process: Another action pose, then the word "Corruption."
UltimateShape: Curved blades form on the forearms, extending a couple inches past the elbow. The armor around the wrists grow thicker (See weapons), and a 5" horn extends from the helmet. A large jetpack forms on his back, shaped in a similar way to the Av-matoran of '08. Despite this, the hidden jet boosters are still usable with the jetpack, although they now function as afterburners. Boosters are also added to his feet.
Weapons: The katana and cleaver are both retained, and the curved blades are formed. The thicker armor on the wrists are actually Ki cannons that are activated at will. They will extend over the hand and past that a couple inches, allowing Kenji to ampifly Ki blasts beyond usual. The downside to this is that it takes a couple seconds to activate/deactivate these, leaving the hand unoccupiedfor that span of time. Also, they can't be used if the hand is holding something. The horn can be used in conjunction with both arm cannons to create a Ki tri-blast. On it's own, it's useless.
Activation process: An action pose, followed by "Ultimate."
Corrupted UltimateNote: this form can only be used if:
A) Kenji goes ultimate while being in corrupted mode
B) Corrupted Kenji
somehow crosses with another Kenji, who is in Ultimate mode.
Color: See Corrupted.
Shape: Portions of both armors are used. The spikes on the shoulders and streamlined helmet with spikes are retained from Corrupted mode. The horn, jetpack, and boosters are kept from Ultimate mode, along with the curved blades. The curved blades are shorter, however.
Weapons: Ki katana, cleaver blade, arm blades. He also gains small, 1" spikes on his knuckles.
Activation process:From Corrupted: Follows Ultimate Activation, but the words "Corrupted Ultimate" are added after the transformation.
Cross: A duo-action pose is made. The word "Cross" is said by both users, and the transformation is made. Both users then say "Corrupted Ultimate."
Armor crosses with othersDepends on the other person.
