Alright, first off I'm never getting to Soma's PC form most likely, so if anyone wants to take care of that they can go right ahead.
I would like to address one thing about Soma's PC form though. He can technically be completely invincible with the Chaos Ring and Iron Golem soul. The Iron Golem soul makes him completely invulnerable to absolutely everything, and the Chaos Ring gives him insane enough MP regeneration that he will literally never revert unless the enemy somehow takes his MP away by force. In other words, this combination makes it impossible for anyone who doesn't have a move that reduces your MP to zero or prevents you from using spells from beating him. Furthermore, even if you can get his MP to zero, the Chaos Ring would get him ready to be Iron Golem again within a turn or two, so it's pretty futile unless you can OHKO him or can survive a few turns of physicals from Iron Golem (he's restricted to his normal physical as Iron Golem). So, as if the Chaos Ring wasn't bad enough as it was, Soma's completely broken if you let him use it with Iron Golem. The Chaos Ring is pretty hard to get though, so when you combine that with crazy effect it has, I'd say it's probably best to just not let him use it.
I love acting like Soma's going to ever be in the actual DL or something.
