Yin-Yang to Sinistra (despite both being Antagonists)

Billions of years old

No concept of gender, seen as male

Acigokon, God of Antimatter; The Anti God

Eldritch

Red

eight metres

A reptile like creature covered in hard, charcoal grey plates. Size may vary. A shell is present upon his back, and his head is very beak like. Red lines for eyes, though some of it must be markings. Somewhat shorter arms but not T. Rex short arms. Long, crocodile like tail.

Ton and a half.

Normal size is around 5 metres. During his first battle against Sinistra, he was around 302 metres. Can change size.

Generally laid back but similar to Sinistra, he is an opportunistic predator. He takes pleasure in causing misery to her/it especially but just about anything will do.

Acigokon is a lot more aggressive than Sinistra. He has little to no mercy. However, he is not outwardly aggressive, and this only applies to fights. Overall, he is generally calm and patient.

Unlike Sinistra, Acigokon may be willing to work with others and leave them alive.

Acigokon is an incredibly aggressive fighter, focusing on a run and attack style; he runs at his foes, attacking them in a flurry of movements, then retreating, again and again. In his 'Eldritch form,' the stakes are still the same, but he's more of a long arrow piercing his prey in that form.

Living up to the name, 'God of Antimatter,' he can control it. He rarely uses that ability, so it's debated whether or not he should keep that name. When normal matter touches his antimatter though, it becomes a weapon to be feared on the battlefield (as when it touches each other, they destroy each other and send off a lot of gamma radiation.)
