Okay the first one is too powerful. (The titan has super strength. The strength equivalent to a lietenant ranked shinigami) It would be like having a second character fight with you. And also combine that with the ability to merge, and makes it even more insane. I like the idea, but tone it down a little.
Also hell's angel, boosting his speed to quick step speed is a no, that would be like a shinigami, shunpoing constantly, never being visable(cause your moving so fast)
The demon gate is unnecessary, that's what makes shinigami, and arrancar/hollow unique, you can make a gate, like urahara, but no portable portal.
What is super strength?
Having a display of vital data is fine, like power level, physical status(heart rate, fatigue, etc.) but no showing, past conversations, movements, and abilities (besides movement how would you track/discover those anyways)
Tone the golem some, He's meant to be a fighting companion, not a second character
Lower the suits power alot, and give it a drawback to using it, like you have to put it on at home, or something, you can't carry it with you , just think of something.
