Ben 10: Infinity Theme Song

Season 1 Theme
It first shows Ben saying, "It began once again, I had to be a hero. But now, it's different. This is Ben 10: Infinity."

Then it's the Ben 10 Alien Force Theme showing all of Thomas' Fusions.

At the end Ben presses the Infinitetrix appearing the Logo.

Season 2 Theme
Our World's about to break. Tormented and Attacked Lost from when we wake With no way to go back I'm Standing on my own. But now I'm not alone (Avengers Assemble).

Always we will fight as one, Till the battle's won with evil on the run we never come undone

Assemble, we are strong Forever fight as one Assembled we are strong Forever fight as one
