Added some description, etc. as per your post. I think I covered most of the major emotions, if another one comes up in battle I can describe then what happens? It's all very circumstantial, so I'd elaborate as needed in battle.
SIGNATURE MOVE APPLICATION
Terra (Female)
Ability: Steadfast
Experience: -none yet-
Approval: Starting Team
Signature Move: Aura Manipulation (Unless I think of a better name later)
Description:
Terra taught herself how to do intensify Pokemon's emotions, as a defense against dangerous Pokemon. It is already within most Riolu's power to sense the auras of others, she realized that it is possible to affect a Pokemon through their aura through necessity; as a young Riolu in the wild she was always in danger of attack from some Pokemon or another, so she developed the ability to distract them for long enough that she could run away.
Aura Manipulation lets Terra sense the emotions of a Pokemon and intensify them to be used against the Pokemon. Rage becomes 'blind fury', they are so mad that they simply lose their grip on reality for a time. Sadness becomes depression, effectively rendering a Pokemon immobile due to instilling a 'why bother' feeling. Confidence intensified can cause Pokemon to put themselves in more danger than is necessary. Nervousness, obviously, makes the Pokemon very afraid and not wanting to have anything to do with the battle. Attraction intensified causes a Pokemon to be totally enamored, unable to hurt the Pokemon to which it's attracted AT ALL. Confusion intensified causes severe dizziness, inability to move in a straight line or see straight, etc. (kinda like being veeeery drunk)
However, there are some emotions that simple can't be turned against someone. Determination, for example. This will only cause the Pokemon to become more determined Or happiness, most of the time. This will simply mean that a Pokemon is even more content. However, happiness in a 'everything is so wonderful etc. etc.' way can make the Pokemon not want to hurt anyone. Calm, if intensified at low strength, simply makes the Pokemon more calm and level headed, though at high strength can make them uncaring about what happens, so they don't bother to defend themselves.
If Terra uses it first thing in a round, it will be more powerful, but will leave her exhausted and unable to attack for the rest of the round. The strength at which she uses it determines how long the effect lasts and how taxing it is. It is very taxing in general to use it though.
Terra concentrates deeply for a time, meditating and developing a slight blue glow as she looks through her 'other sight', the aura sensing sight. The blue glow intensifies as the effects come into play.
Type: Psychic /
Stat: Special /
Accuracy: 100% /
Target: 1+ Pokemon /
Energy: 8%+ /
Duration: Depends on strength, at least 2 actions and as much as 2 rounds
Effects:
Intensifies the strongest emotions of a Pokemon, causing confusion/depression/whatever is the extreme of the emotion.
The energy usage begins at 8, this being an effect that lasts only a couple actions, only intensifies an emotion a little (ex. sadness just becomes a 'sigh, this is bad' feeling, not full blown depression), and only targets one pokemon. in general the energy usage increases by 1 point per extra action it lasts, 2 points per extra enemy, and as for intensification level, at it's strongest the energy use increases by 6 points from the weakest.
Usage Gap: Can only be used once per battle.
