More running gags to come, for starters the displayed powers are already whacky on their own.
1) Evan is a litter bug: he tosses stuff on the ground frequently. This includes his swords/blades (made from his spit), he just tosses them when finished with battle (as he can always make more).
2) Evan tries to turn monsters into swords
Evan's 1st battle he found luck converting a monster worm into a sword. As he continues to explore his abilities, he tries to make swords from other monsters he encounters but no luck!
(this worm-sword was a total red herring, bec he parades into the 2nd battle with it, lost it within seconds of the fight> leading him to discover his true abilities)
And a few episodes after he says about another monster:
3) Big There's also another gag hinting Evan has 'a massive sword of another kind'.
4) left behind - when the battle is over/place is clear, Evan has a habit of leaving his lil bro, Owen behind
