@Mr Quest

Owen, Izzy and Zeke appeared in TDAS because they seem to be considered the mascots of cameos by FreshTV, given their particular antics and roles.

Zeke camoed several times as "the monster of the day" (to use an X-files expression) and the mutated Wawanakwa looked as the perfect settlement to keep him having this role. He always appeared to be defeated in a single episode since TDWT. That's why he didn't appear in Pahkitew, think about it.

Owen is the MASCOT and top favorite character of Tom Mc Gillis, so he HAD to at least appear in TDAS. (They replaced him with Sam just to not waste him as a fodder and justify his return in RR without annoying the fandom).

About Izzy, in the first three seasons the writers have been very inconsistent with her, so they recycled her as the cameo-pet for ROTI and TDAS to please her fans (that were many in the past, I don't know nowadays). If Noah and Geoff returned for RR, I expect Izzy to return in the 6th season as a contestant or cameo again.
