Did a whole piece and a doodle to celebrate!! This show means so much to me, so I want to go all out for it!!
Here is an alternate version of the doodle I did, I'm not really fond of it 💀 I wanted to include as much as many characters as I could but, I was rushing 😭 Hope you all like it tho :')
How tall would you say the main characters and the main antagonists (that DON'T change shape thank you very much) are?
Well, the only thing that stays consistent is the order of their heights. The ratio fluctuates a lot, like how sometimes Kimiko is close to Omi's height and sometimes she's close to Raimundo's. And it switches back and forth, so unlike Jermaine, Kimiko's not just because of a growth spurt. And Clay is sometimes barely taller than Raimundo, and sometimes a full head taller.
But as a baseline, I think Chase is around 5'8'', maybe a little less. He's not tall.
And I think Clay is either the same height as Chase or slightly taller. The ratio between Clay and Chase the few times they're on equal grounds is never consister, but I use this scene as my basis.
Sibini is visibly slouching here, but he and Chase are at eye-level.
So I think Clay is 5'9''-5'10'', give or take, maybe a bit taller. But Daddy Bailey's at least 6' with how he towers over Clay, probably like 6'5'', so Clay's probably due for a growth spurt still. (You know, Clay looking shorter than he is a lot can probably be diagetically explained by Clay slouching, specifically because he's a bit insecure about how much taller he is than his friends. He probably only stands up straight properly in his dad's presence.)
Kimiko's 4'-something. Maybe 4'4''?
Raimundo's probably a foot taller than Kimiko, so around 5'4''. And Jack is a bit taller than that at 5'4-and-a-half''.
Omi's... canonically 20 pounds, that is lighter than a 1-foot toddler is supposed to be. And Omi's ratio next to the others easily fluctuates the most. But we'll say he's... about 3' ?
Wuya stands almost level with Chase. Tip toes adds about 2 inches, maybe 2.5, so I think her real height would be about 5'5.
If she stood flat on her feet, she and Jack would probably be about the same height.
This is my first time trying to do height headcanons, so these are very rough estimates. But it'd come out to something like this (Daddy Bailey added to reference with Clay)
