The Shinobi is the first Paradox kit to have melee weapons instead of long-ranged weapons, like the Sorcerer and Space Marauder. The Shinobi was the last Paradox Kit to be released.
A traditional Shinobi is a covert agent or mercenary of feudal Japan specializing in unorthodox arts of war, otherwise known as a ninja.
The Shinobi, along with the other third specialty kits, was released in the August 9, 2011 update, named the "Power of the Nexus Force" update.
Sutoro Hatto in Nexus Tower can be seen wearing Shinobi gear.
The Shinobi seems to have a rather slow attack speed, which allows some attacks to get through.
The Shinobi rush is similar to a shield slam attack.
The Shinobi's shuriken are called the Shuriken of Kintamo.
It is the only Paradox kit to have two-handed non-Valiant weapons (Rank 2 and 3 only).
On January 2nd, 2012, a mythran handed out the rank 3 shinobi kit along with other kits from all four factions (one each.)
The Left-handed Shinobi weapon Proxy was given out in a give away on Jan 25. It gives no stats, but it lets the player use the Shinobi Rush attack, and any faction could use it.
The Shinobi's weapons are known in real life as Hook Swords, an exotic Chinese weapon traditionally used as a pair, as shown in the in-game Shinobi's weapon.
