It's finally revealed what happen to Phil who was first and last seen back Ben 10 Season 2 Episode 1 "Truth" after 6 years.
Ben mentions losing his hand in the Null Void once. This happened in the Ben 10: Alien Force episode "Single Handed."
Big Chill: That's two times I've saved your butt today, Rook. But who's counting? Oh, that's right: I am! One, two!
Ben: (after Rook saves him) Too ya long enough! I had this jerk telling me his whole life story, trying to buy time before you waltzed in!
Rook: I.. do not know how to waltz. However, my Earth culture texts did tell of a dance called-
Ben: Skip it.
Rook: I do not know how to skip either. Oh, Earth expression?
Ben: (touches his nose) Bingo.
(Rook touches his nose)
Ben: Also an expression.
Ben: Get ready to throw down with... Humongousaur! (changes into Rath)
Rath: Lemme tell you something, so called "Greatest Hunter in the Galaxy". Rath may not be Humungousaur, but he's gonna make you Humungousorry!
Khyber: You would do well to show respect to the greatest huntsman in the galaxy.
Ben: If you're so great, how come it took you five years to capture me, huh? It took Vilgax like, five minutes!
Ben: So, uh, Khyber, is it? Love what you've done with the place. Who knew alien skulls had so many uses?
Among Khyber's hunting trophies are Grimlock's fire sword and Lockdown's hook arm, from showrunner Derrick J. Wyatt's previous work, Transformers Animated.
Rath and Khyber's "Khyber season"/"Appoplexian season" arguement mirrors Bugs Bunny and Daffy Duck's "Duck season"/"Rabbit season" arguement in the Looney Tunes short "Rabbit Fire."
Rath: Khyber Season!
Kyber: Rath Season!
This is a very direct reference to the classic Warner Bros cartoon "Duck! Rabbit! Duck!" in which Bugs Bunny and Daffy Duck keep saying "Rabbit Season!" "Duck Season!"
