Protoform X

Protoform X is an experimental Cybertronian form from the Transformers universe.

Physiology
being the only one of his kind it safe to assume that Protoform X stands over 10 feet tall if not more.

Rampage as he is otherwise known as, has an experimental spark that is almost indestructible and can only be damaged or destroyed by an Energon blade.

even if he is damaged to the point when he is in several pieces aslong as his spark is undamaged, he will rebuild himself.

This invincebility is gifted to him at the cost of his sanity, as he is sycotic in every way. Unlike all other transformers he feeds on the emotions of others, especialy negative ones like pain (both emotional and physical) and fear, he is also a cannibal having eaten his creators (an entire colony of Maximals).

History
After his creation and the slaughter of his creators he was eventualy subdude and transported to a space station to be executed, there it was found that most conventional weapons prooved inoffective against him and was later quireed weather or not his spark could be terminated.

He eventualy broke out of there too, killing and eating many of his captors before again being captured by Depthcharge and put into staces.Deapthchagre took him before the Maximal high counsil and requested to personaly end Protoform X's existance but the council denied this and stated that he be cept in permanent staces.

He was placed onboard the Axalon a Maximal scientific vessel. but was inadvertently released from his slumber when the Predacons attacked.After a series of events in which he blasted his way through both factions without signs of stopping and ate Tarantalus (or bits of him atleast), he was blown of a cliff face and lay unconchous until Megatron (The Predacon leader of no relation to the Decepticon) cut out a portion of his spark using an energon knife and renamed Protoform X as Rampage (after his actions on the day).

Under Megatron (who held him prisoner, crushing the portion of the spark whenever Rampage showd signs of disobedients) Rampage fought many battles with the Maximals.Until a grudge bearing Depthcharge (who had freinds on the station where Rampage broke out of staces) arived.

The two had many battles of thier own, both of them serviving massive damage including rampage being impaled and depthcharge have a peice of his back ripped off. Eventualy Rampage was killed by Depthcharge when he grabbed a solid shard of energon and stabbed Rampage Through his spark, although the resulting explosion killed them both.
