Before I suggest anything, there are some things on the profile that needs fixing. 4-B is Solar System level, not High 4-C, so buff him up to that.
Since your character power scales to Kingdom Hearts, I don't think you need a reasoning for the AP, though it would probably be good to say (Comparable to "insert 4-B KH character here"), or something similar to that.
Also, the power between Solar System and Galaxy level is
very broad,
as seen here. Tanking attacks from a 4-B does
not mean your character is Galaxy level, and we don't know the power of the laser cannon's beam unless you tell us. This means you have no proof of your character being Galaxy level in durability, and is probably more towards "At least Solar System level", since they're able to tank attacks from another 4-B.
Also if I seem a bit harsh here, I'm sorry. I just don't want your character to be innacurate and possibly deleted, which mine almost were. Funny, when I first joined this wiki I was given the same critiques, though it was from an admin, and after a few offenses I nearly got my characters deleted. Good times...
