You can activate one of Ajani, Nacatl Avenger's loyalty abilities the turn he enters the battlefield. However, you may do so only during one of your main phases when the stack is empty. For example, if Ajani, Nacatl Avenger enters the battlefield during combat, there will be an opportunity for your opponent to remove him before you can activate one of his abilities.
Ajani, Nacatl Pariah // Ajani, Nacatl Avenger
You don't choose a target for Ajani, Nacatl Avenger's second ability when you activate it. Rather, if you control a red permanent other than Ajani, Nacatl Avenger, a second "reflexive" ability triggers when you create a Cat Warrior creature token this way. You choose a target for that ability as it goes on the stack. Each player may respond to this triggered ability as normal.
If an opponent doesn't control any permanents of one of the types, they'll still choose the permanents of the types they do control.
