Kingdom Hearts II How do I make Terra loop?

I've been trying to find out how since I got to the battle.

 

It's really hard on him,he is unpredictable sometimes.
It depends on the move he begins the fight.

 

Yeah, I noticed that, but what move does he have to start on? Also, I did get him to loop once, but it was his DM.

 

For me it's easier when he starts with the "Rising Sun" attack or the canon.

With Rising Sun is easy,you just need to do three combos with 1 finisher(and the finisher should be Explosion)after he stops,then he will use it counter you with Rising sun(He will use it Twice and then use the Whip attack) or he will just use the whip attack and then stop again,but after sometime,his counter will change.

As for the canon,he will just keep using the Arrow move,and if you don't attack he after it,he will use the canon,it's easy,since he only uses these two moves(Unless you do more than three combos,if you do he might counter).
The problem is if you stay much time using this metod he will eventually cast Magnega to catch you when he is using the arrow attack.

 

Magnega? I didn't know he could use that.

 

He can,and it's unpredictable,he just do what usually does and the Magnega appear next to you.
And he can use together with other moves besides the one i said.

 

I'm going to move this to the Help section so that it might be more addressed and it belongs there.
