Very creative and thought inducing, Anoni, very interesting to, sounds different. I'm liking these ideas!
I made up a back story for Isscarus. He was born as an immortal God in the Galaxy Acropalypse, Acropalypse was Isscarus's father, and he found the Galaxy, so he named it after himself.
Isscarus was the strongest out of his brothers, and the oldest, besides Isscarus, his other brothers were (from youngest to oldest): Bruno, Lith, Solace, Velwind, Shiros, and Gongyss, who all had godly powers just like Isscarus, however each of them had different strengths and weaknesses.
For example, Bruno, the youngest of the family, was superior in speed than most of his brothers despite being the youngest, and Shiros was powerful in magic and spellcasting, Solace was helpful as he boosted his brothers strength and abilities,making him very supporting, Lith was a healer and used restoration powers to heal wounds on his allies and hurt feelings, and Velwind was an illusion master and could trap his enemies in alternate dimensions or send them to other universes.
And Isscarus had sheer strength and power, he was also very intelligent, being both the muscle and the mind of the bunch, and as being oldest, he has to protect his brothers with his life.
Isscarus has very impressive feats, even with his power suppressing armor, he was able to destroy a planet with his ultimate attack, he has also survived attacks from gods WAY stronger tgalaxym, he's survived being thrown through planets, his greatest durability feat is just barely and I mean BARELY surviving a supernova, he didn't survive the actual explosion, only the blast wave, but then again a blast wave of a supernova can destroy planets.
His best strength feat is being able to stop a planetary collision with his bare hands, however even though Shiros has better energy projection, Isscarus isn't far from him.
His best energy projection feat is being able to blow up a galaxy, but remember, even though this is an extremely impressive feat, he had his armor destroyed, unleashing his power, he was also using his full power and was in his ascended form, and he nearly killed himself destroying the Galaxy, so he should probably never do it again.
So yeah, he's a galaxy buster at full power, but then again, you guys probably have stronger God than mine.
I'll tell you some more of the backstory in a little while.
