I just notice while watching The Suite Life on Deck (I like mature shows over than kiddy shows), Cody is almost identical to Donghae (don't even bother ask why my blog is almost Donghae because he is my bias now though he used to be 5th bias when Kyuhyun was 1st before now).

Facts: 

1. Both are younger than older members though Donghae is a bit older than Siwon, Ryeowook, Kyuhyun and Henry.

2. In one episode of season 2, Cody dressed as a chef which almost illusion to Donghae played as Go Seung Ji in Panda and Hedgehog (Both look cute in chef uniform).

3. Both can be very emotional at times.

4. Another episode in season 2, Cody is a bad boy, once again, almost illusion to Donghae played as Shang Jieyong in Skip Beat. (They can be y when they are in bad boy mode)

I almost thought that Cody in various episodes a illusion to Donghae's future roles in drama. 

Kichen Casanova (Chef Cody) - Panda and Hedgehog (Seung Ji)

Bermuda Triangle (Bad Boy Cody) - Skip Beat (Shang Jieyong)

Cody being a regular student - It's Okay, Daddy's Girl (Wook Ji)

Cody doing towel job - God's Quiz Season 4 (Shi Woo)

Exception with the movie roles Donghae has been there, they are almost identical to each other though I kinda want Donghae to meet Cole Sprouse.

Gifs or Picture of them being similar:

Both are being so awkward 

Both can get very emotional (since both actors do cry at times) 

Both can be very angry to other people at times 

Their smile is so cute and adorable 

Both of them being bad boy are y and hot

Both can cook well (though Donghae is not really good chef) 

Both doing their jobs (Cody being towel boy while Donghae being doctor)

Both can be unsatisfied sometimes
