>> Good Lord... Now I know how Milady feels... Where to start?
Okay, I'll begin with the Strengths and Weaknesses. His only listed strength is rather vague,
As for the Appearance, I have no idea how Chrono looks, and I doubt I'm the only one. In fact, I don't even know what "Chrono" you speak of. For all I know, there could be dozens of them spread throughout the anime/manga universe. I naturally assume you're talking about the main character from Chrono Trigger, but I still don't know what he looks like. He was a sprite, anyway. Please provide a graphic description of what the character looks like. Remember, the Appearance is the third most important thing about a character.
The second most important thing about a character is the biography. Remember, there is nothing wrong with being long-winded with a bio. Be as descriptive as you can, and remember to avoid revenge stories at all costs. >< No offense, but the "I'll avenge my dead family" plot is the most overused cliche in the history of literature.
Now for the most important part: Personality. Knowing how a character looks is important in many cases, but knowing how they will react to something is
imperative to role-playing...especially when power-playing is so common. ("Power-playing" is the controlling of others' characters.) Look deep into Irako's psyche, and think about what he's truly like. Nearly all people have a multi-faceted personality; they can't be described in two simple sentences.
Go all out, and remember to enjoy writing your character's profile. The more you enjoy it, the better it will be. 'Tis an unspoken law of the written word: the secret ingredient is love. ^^
