Act On You?
As is the case with all shinigami, Aizen has the ability to sense unnatural/supernatural energies. In theory this could include demonic, divine, spiritual/etc energy, but it's mostly focused on spiritual power/pressure.
For the purposes of
scorched, he can also sense other types of unnatural/supernatural energies, such as chakra (Naruto), yoki (Claymore), etc, although he isn't as good at reading alien energies as he is at reading reiatsu.
In any case, this can be done over rather impressive distances, and larger energy sources can be read from longer distances.
SO:
01. Can Aizen sense anything with your energy?
02. And if so, how powerful is your energy?
Obviously 02 is fairly rough - a good idea of how strong the character is in the context of their own canon should be good enough, although if you want to give me more information, that's fine too! Any blockages will be written off as the mist messing with her.
Act On Me!
[OOC]
Backtagging: Maybe. Generally, if you're replying to a network or voice mail comment that's more than a day or two old, I won't reply. This isn't definitive though - if it's a significant thread (important for bonding or plot, or just intense or deep) I will probably reply. I'm much more willing to backtag with logs, especially full prose logs. However, please note that taking days between comments (especially network or voice mail replies) is habitual for you, I will probably stop check out of our threads/be reluctant to go indepth with you. This doesn't mean I'll check out/stop replying if you're busy for a day or a week, etc, but if it's constant then I probably will.
Threadhopping: I love threadjacks. Do it. Please.
Fourthwalling: Technically this game doesn't allow it at all. Please don't.
Offensive subjects (elaborate): I'm pretty tough to offend. If you intend to do a graphic description of child abuse, necrophilia or bestiality... well, please don't. Otherwise, I probably don't care.

Hugging this character: You can try, but odds are that he won't allow it.
Kissing this character: You can kiss his hand and call him God. Otherwise, he probably won't allow it.
Flirting with this character: Flirt all you want. There's a good chance he'll ignore it look at you in a disdainful manner.
Fighting with this character: I don't mind, but it requires some plotting to make Aizen actually fight, himself. Usually he just sends in minions to do his dirty work. Now that said, before you go and pick a fight with Aizen, bear in mind that he's not the most infamous godmode in recent manga without cause.
Injuring this character (include limits and severity): If you can hit him? I don't mind at all, he regenerates anyway.
Killing this character: MAYBE? If the plot calls for it, and the setup makes sense.
Using telepathy/mind reading abilities on this character: It's hard to say since Bleach doesn't really have much telepathy going on... but his will is exceptionally strong and I don't want his plots getting out, so ask me first.
Energy Sensing: By default, Aizen does absolutely nothing to hide his energy so go ahead and sense him unless I indicate otherwise. As for what that feels like, by default it drives lieutenant level shinigami's bodies to go limp and when he releases more than his default, it forces captain level Hollows to their knees. Even before his enhancement via Hogyoku he is known to have at minimum twice the reiatsu of a normal Captain, and ultimately he's revealed to have personal power in excess of all ten Espada (who are roughly captain level) combined. So we'll go with "vast."
Warnings: He looks down on you. :|
