Actually the fusion was created after Nektann had already allied his army with Teridax. Plus, the Skakdi warlord organizing the event stated that they were doing it to make a name for themselves, and not have to follow Teridax's rule. So whatever influence Terry had, it was all behind the scenes.
I thought it was a bribe to get the Skakdi (and Nektann) on his side. If he could make their dreams come true, then they would do what Teridax wanted in exchange for the dream being granted.
Also, since Zaktan was controlling the fusion, he likely would be okay with following Teridax. He did talk to Teridax before when he was in that glass case, and to Zaktan's knowledge Teridax hadn't betrayed them. In fact, what Zaktan wanted was a part of the Plan, and Teridax was finally giving him what he wanted. I think it adds up.
Also, I don't think it was ever proved that Zaktan controlled the fusion... was it?

Their mission here was as simple as it was perilous. The Order had learned that Nektann, a powerful Skakdi warlord, had allied with Makuta Teridax and led his army on a journey south. Now it was vital to find out if any of the other warlords were going to follow his lead.
On top of that, there was a mystery to be solved. Following the widespread destruction on Daxia, the sea snakes that were once the evil Piraka had vanished. It had been believed they were just buried in the rubble, but rumors were flying they had been rescued and spirited away to Zakaz. For what purpose, no one could say.
I thought this was that Teridax told Nektann how to build the fusion - and perhaps, what it would do - and Nektann agreed to an alliance.
“For too long, we have been penned up on this island, by the will of the Brotherhood,” the warlord continued. “And now one of their number controls our universe, and believes he controls us, as well. But we will show him he is wrong!”
“Okay, well, it doesn’t sound like he and Teridax will be playing kolhii together anytime soon,” said Jaller.
“And I think he’s just getting warmed up,” said Hahli.
“Let our salvation now rise,” shouted the warlord.
“Here it comes,” said Nuparu.
Now I'll concede this point - he does make the speech. But then again, he's in the middle of his troops, and is likely to say whatever they will go along with. Skakdi historically don't like Makuta, so he probably said what would make them happy in terms of opposing them in order to get the fusion made.
The illusion/lie could be kept up, seeing that Teridax has faked defeats before.
With that said, it's possible, technically, that Nektann thought he was opposing Teridax by building the fusion, and that Teridax duped the Order into thinking that he had an alliance with Nektann and sending the Toa Mahri down there, but I think that Occam's Razor might apply (one deception of the troops instead of two), thus leading me to believe that the former explanation is more likely.
It is virtually confirmed that Teridax was involved, though, since he would be involved in sending Zaktan there at the very least, if not all of the Piraka.
