The Planet-Eater, The Chaos-Bringer

Unicron, planet-mode.
Dead End sits in a recess above Unicron's jaws, and the large orange
pincers can be moved to make the jaws close. Minicons can be attached
to Unicron's outer ring and to the missile pods at either side.
In planet-mode, Unicron can carry up to 27 Minicons...
...which is almost all of them.

Unicron's chest houses his Ultimate Weapon, fired by plugging any
Minicon into his back...

The firing mechanism works well; the chest opens as the
missile pod is deployed, and when the missile fires,
Unicron's eyes light up.
