After Seth defeats Linne in his Arcade ladder, he proceeds to restrain her... by wrapping her up in a bamboo mat and hanging her in a tree. At the end, he just leaves her there, as she shakes around trying to break free.
Eltnum's entire Arcade story, where she lampshades the hell out of her status as a Guest Fighter, and completely obliterates the fourth wall.
When Mika enters a fight, she trips and falls on her face, before nonchalantly getting back up and getting the first round started.
If she wins a match, Mika will accidentally toss one of her giant gauntlets into the air, causing it to fall on her head, causing her to suffer a Cranial Eruption.
