Just to follow up:
1) Yep, that is definitely Glamdring (from the movies, at least). One of the top three most badass weapons in Middle Earth.
2) Just verified that he is carrying Skeletor's staff, the Havoc Staff, from the newer, more intelligent, badass and lethal version rather than the 80s version. According to the Wiki, he can use it to fire beams of mystical force or to focus more powerful forms of magic.
3) Shredder's bracer: Don't think it has any special powers, other than being vicious. From the original black & white TMNT comic Shredder (who was brilliant and unrivaled in his martial arts abilities save for Splinter).
4) Parson's Bracer: Do we know if it has any abilities other than Mathamancy/Predictomancy?
5) Other accoutrement: No idea whether the cloak & helm possess any special properties...
But...questions: If he can use the Havoc Staff, does that mean he can channel innate magical abilities? Does it require a caster to function?
Overall, he is carrying a minimum of four items which symbolic of highly intelligent, highly competent BAMFs. Parson has not taken a level in badass, he has taken multiple levels. If he can wield each of those items to their fullest, well...it will be a very bad day for Jetstone, et al. A combination of ranged (magical, from the Staff) and melee (Glamdring and Shredder's bracer) should make the Lord Hamster a force of nature in his own right.
