http://www.furaffinity.net/view/5597658 is evolving into Fenris! Your B button is jammed however so best run for the hills after piddling yourself.

Name: Fenris (Technically Sinefir but he boasts this new name, claiming he's become something way past a mortal being)

Species: Hybrid, his echidna attributes having been supplanted with wolf ones.

Sex: Male

Height: 6'1'' (a solid shrinkage from his fully-engorged Adult form's 8'!)

Abilities: He has all of Sinefir's abilities, but now has some extras added on:

-His deadliest capability is he can suck all of the negative energies of the world directly into himself, making him nay-unstoppable. He can do this from any location, no longer needing to energise people at all.

-Accordingly, near-unlimited reserves of power allow him to do just about anything

Weaknesses:

-Despite his seeming invincibility, he has one fatal weakness: the only energy permanently absorbed comes from the most corrupt souls, who he has directly integrated into himself. If one was to remove all the others in some way...

History:

Just as Sinefir appears to be on his last legs, he reverals that he's been bluffing his "final" form all along to get his enemies to lower their guard. With a quick absorption, he upgrades to his true final state, making himself practically unstoppable. Will Veinsufin's ambitions finally be realised?!

Physical Changes:

All his spines have been shed, instead, rock-hard protrusions have erupted from his knees, shoulders, elbows, and head. The horn-like protrusions on his head, if all seven are counted, look almost like a literal Crown of Thorns, a testament to his perverse ideal as a cleanser of sin. Some large spikes have erupted from his back, slightly replacing the many spines he lost.

His tail becomes more wolf-like, while his fist-spikes now are on each knuckle as opposed to being between them, having returned to his four-fingered state.

His fur patches have repositioned themselves, so his torso almost appears to have a draconic shape in the fur.

His clothes have evaporated, now only possessing a loincloth with many symbols - mainly the Omega - on it.

His height has drastically gone down, 3/4 of his previous form's height, but still large compared to most people. He still retains intense musculature.

Most prominently, he now has "wings." These are not used for flight, but as additional weapons. They manifest as balls of light forming the basic shape of the wings, with streams of light forming between them. He can actually use these as weapons to shoot and impale enemies.
