Finally got around to making a height chart of all the Ben 10 ocs I have placement for / will forever keep.
Split into two sides, Annos' & Llewellyn's due to their two different aus and timelines.

On the Left we have:
Annos - Highbreed - Male
Soul - ?? Space fish-cat alien - Female
Zaveck - Lentesorite - Male
Hunter - Ectonurite - Female

The on the right is:
Makenzie - Human - Male
Billy - Lentesorite sona - Male
Llewellyn - Human/Osmosian - Male

I cannot take credit for Soul or Hunter's designs, both ocs I adopted and their credits can be found on their Toyhouse pages, I did design everyone else though.

I have both Annos & Llewellyn [w/ the sona friend] uploaded to Artfight this year and I really hope to get some more art of both of them, it's Annos' second year on their and Llewellyn's first. I absolutely adored some of the art I got of him last year and as two of my biggest comfort characters right now I'm excited to see what else they could get.
Also working on some non-canon / slightly-au Annos concepts so that Llewellyn and Annos can interact cause they'd have a lot to bond over by being seen as outcasts even by their own families.

UPDATE:
Finally came up with my canon design for Llewellyn's half-brother Makenzie, though I feel if people think hard on his name they'll fall into the lore I have of him and have not been sharing lol.
Alas though, them hanging out in these designs will be non-canon for now, rip their sibling relationship at least Llewellyn's getting to live his best life rn.
