Summoning Triad

With the powers of his Rinnegan, Irikuchi summons of a trio of animals, beasts. Each a master of the basic ninja fields. The red beast: a master of Taijutsu. The yellow, a master of Ninjutsu. And the blue, an adept avatar of Genjutsu.

Each master cannot be defeated by what they control, showing absolute supremacy in the field they control. It is useless using taijutsu against the red dragon, and so on.

Drawbacks
This technique can be beaten rather easily. If the beasts are attacked by anything rather than their field of mastery, as long as it can destroy a massive summon, they cannot defend against it, unless it is stopped by another of the triad. Also, the triad can work together if Irikuchi commands but cannot launch attacks or jutsu at the same time, it cannot be done.

Trivia

 * This technique's drawbacks come from Buddhism. Animals in that religion don't like anything unusual to them, resulting in their defeat in other ninja fields. This is also why they cannot work together exactly.
