A section of a Gundam AGE poster showing a beam lariat for the Gundam AGE-1T Titus. It looks like a beam energy lasso surrounding the Titus's wrist. Now the Gundam AGE-1T Titus was described as being a boxer / wrestler type mobile suit, so perhaps this beam lariat would enable the Titus to lashes out in some sort of melee attack.
Gundam AGE is scheduled to air on Oct 9th in Japan (channel: TBS/MBS). It has not been confirmed whether the series would be airing one season or two.
