In the ROTF flashback exposition the Matrix floting a Prime's hand then the Fallen snatches it telekinetically. Later in that movie the Fallen messes up the almighty US military by himself. Levitating them then dropping them. In DOTM we find out that the Matrix naturally floats. Our assumption was the original Primes all had that telekinetic ability. Given what we saw in DOTM it sort of justifies that the Fallen was more powerful than his brothers. If he was the only Prime with that ability.
