Hyperion might have had a major collision which blew part of the moon away. Its eccentric orbit makes it subject to gravitational forces from Saturn which have set it tumbling out of control.

Hyperion -- In Greek mythology, a Titan, son of Uranus and Gaea. Husband of Theia and father of Eos (the Dawn). A handsome wanderer, his name is said to signify height or superiority.
HYPERION
Hyperion is one of the 18 moons of Saturn. Hyperion is the largest-known irregular-shaped body in our Solar System. It has a variable rotational period. Craters mark the surface. Iapetus has a radius of about 180x140x112.
Saturn's moon Hyperion is the only object in the solar system that is known to lack a geographic north pole. It rotates chaotically due to a combination of its irregular shape and tidal influences from nearby moons.
Hyperion (NASA Thesaurus / NASA SP-7, 1965) A satellite of Saturn orbiting at a mean distance of 1,481,000 kilometers. hyperkinesia (NASA Thesaurus) Excessive exercise, that is often accompanied by uncontrollable muscular movement.
The satellite pairs Mimas-Tethys, Enceladus-Dione, and Titan-Hyperion are in stable dynamical resonances, in the sense that they interact gravitationally in a periodic fashion so as to preserve the regularity.
With the same instrument, he further detected, on the 19th of September 1848, Hyperion, the seventh of Saturn's attendants, and, on the 24th of October 1851, Ariel and Umbriel, the interior moons of Uranus.
The strangest motion of all is that of the moon Hyperion, which orbits between Titan and Iapetus, at a distance of 1.5 million km from the planet. Unlike most of Saturn's moons, its rotation is not synchronous with its orbital motion.
By increasing proximity to Saturn, the middle moons are Iapetus, Hyperion, Titan, Tethys, Dione, Rhea, Enceladus, and Mimas.
Why are other ice moons of Saturn such as Phoebe and Hyperion not behaving in this lopsided fashion? According to Tilmann Denk of the Freie Universitat in Berlin, Iapetus is in a unique situation.
The outer satellites Hyperion and Iapetus also consist mainly of water ice. Iapetus has a very dark region in contrast to most of its surface, which is bright.

The next three moons are Hyperion, Iapetus, and Phoebe. Hyperion looks like a hamburger, and has a crater that covers one third of its bottom side. Iapetus has one side that reflects light, but the other side is covered in a pitch-dark material.
The relatively large Hyperion is locked in a resonance with Titan. The remaining regular moons orbit near the outer edge of the A Ring, within G Ring and between the major moons Mimas and Enceladus.
It rotates on its axis every 9 hours, unlike the other moons of Saturn (except Hyperion) which always show the same face to Saturn. It has a radius of about 110 km and mass of 4 x 10 18kg. Phoebe orbits at 12,952,000 km from Saturn.
This sharing of orbits had not been seen before the detailed investigation of Saturns system. Hyperion rotates chaotically because of the influence of Titan's gravity and a highly eccentric orbit.

Hyperion, a smallish, tumbling moon that looks like a sponge;

No further discoveries of significance were made until 1789 when William Herschel discovered two further moons, Mimas and Enceladus. The irregularly shaped satellite Hyperion, which has a resonance with Titan, was discovered in 1848 by a British team.

Saturn's known moons are (from nearest to furthest from the planet): Pan, Atlas, Prometheus, Pandora, Epimetheus, Janus, Mimas, Enceladus, Tethys, Telesto, Calypso, Dione, Helene, Rhea, Titan, Hyperion, Iapetus, and Phoebe.

During the four-year Saturn Tour, Cassini will complete 74 orbits of the ringed planet, 44 close flybys of the moon Titan, and numerous flybys of Saturn's other moons Dione, Iapetus, Enceladus, Mimas, Tethys, Hyperion, Rhea, and Epimetheus.
When it was old enough to bear the weight, the young phoenix lifted the nest from the tree and carried it to the temple of Hyperion, the Titan who was the father of the Sun god.
