Here's some information about Pit.
Pit acquires five bars of health total throughout Kid Icarus. Each bar does not take one hit to get rid of. It simply goes down, kind of like if you had a straw in your cup of soda and you were to suck in the soda. The soda is the cup would lower. It works something like that. Anyway, you can collect a Bottle in Kid Icarus. This restores one bar. However, if you acquire the Barrel, Pit can hold eight Bottles. Moving onto the items that you use at the last level to fight Medusa, Pit has a Mirror Shield. It's actually bigger than the one in Brawl. It protects Pit from attacks. I suppose you can see it in some way like Link's Mirror Shield. (Or should I say Link's Mirror Shield resembles Pit's?) Pit also has Light Arrows, which pierce through enemies. It looks like a laser, kind of. Pit can also fly with the Wings of Pegasus. Also, with the Silver Armor, damage is cut in half. So, um, where is Pit at on the tier list, and why is he there?
