Question about Titan: Does he get an extra phase in Hard Mode?

I noticed in the story mode version, he had a kind of pattern in what he started using. Phase 1 was simply Stomp Tremor and Arm Smack, Phase 2 he had Line Shockwaves, Phase 3 was Heart+Gaol, and then Phase 4 was the little gravity well AoEs (they looked very crystal clear, like fine quartz or the like).

I also noticed he carried (with the exception of the Heart) each attack that he used from prior phases into the phase after it. So in Phase 4, he used Tremor, Shockwave, and Gaol as well as his new attack. My question is: Is there something else that I didn't see during that fight that will be present in HM Titan? And if so, what exactly is it?
